Compress rtf file. How to Reduce PDF File Size Without Losing Image Quality
Now many computers already have hard drives ranging in size from hundreds of gigabytes to several terabytes. But still, every megabyte remains valuable, especially when it comes to fast loading to other computers or the Internet. Therefore, it is often necessary to reduce the size of files to make them more compact.
There are many ways to compress a PDF file to the right size to then use it for any purpose, for example, for transmission over email in a matter of moments. All methods have their pros and cons. Some weight loss options are free, while others cost a fee. We will look at the most popular of them.
Method 1: Cute PDF Converter
Cute PDF program will replace virtual printer and allows you to compress any PDF documents. To reduce weight, you just need to configure everything correctly.
It is worth remembering that a decrease in quality entails file compression, but if the document contained any images or diagrams, they may become unreadable under certain conditions.
Method 2: PDF Compressor
More recently PDF program Compressor was just gaining momentum and was not so popular. But then too suddenly she gained a lot negative reviews on the Internet, and many users did not download it precisely because of them. There is only one reason for this - watermark V free version, but if this is not critical, then you can download it.
The program compressed a file with an initial size of just over 100 kilobytes to 75 kilobytes.
Method 3: Save PDF at a smaller size using Adobe Reader Pro DC
Program Adobe Reader Pro is not free, but it does a great job of reducing the size of any PDF document.
The method is very fast and quite often compresses the file by almost 30-40 percent.
Method 4: Optimized file in Adobe Reader
For this method, you will again need the program. Here you will have to tinker a little with the settings (if you want), or you can just leave everything as the program itself suggests.
Method 5: Microsoft Word
This method may seem clumsy and incomprehensible to some, but it is quite convenient and fast. So, first you need a program that can save a PDF document in text format(you can search for it among the Adobe line, for example, Adobe Reader or find analogues) and Microsoft Word.
That's it in three simple steps you can reduce the size of a PDF file by one and a half to two times. This happens due to the fact that DOC document saved in PDF with the weakest settings, which is equivalent to compression through a converter.
Method 6: Archiver
Most the usual way compress any document, including a PDF file, using an archiver. For work it is better to use 7-Zip or WinRAR. The first option is distributed free of charge, but the second program expires trial period asks to renew the license (although you can work without it).
The PDF file is now compressed and can be used for its intended purpose. Sending it by mail will now be much faster, since you won’t have to wait long for the document to be attached to the letter, everything will happen instantly.
We have considered the most best programs and ways to compress a PDF file. Write in the comments which method was the easiest and fastest for you to compress the file, or suggest your own convenient options.
Hello everyone, my dear friends and guests of my blog. Today I'll show you how to compress pdf file for forwarding or uploading to the site using special programs And online services. I'm sure you work with PDFs often, but sometimes there are times when they take up so much space that they exceed the allowable upload size. What to do then? Don't be sad. All of these methods are absolutely free, so you don’t even have to worry about it.
First of all, I would like to show you how you can reduce the size of a pdf file using online services without installing programs. Naturally, not everyone wants to bet additional application, which will load the system, while one of these four services will come to our aid completely free of charge.
Small PDF
I'll start with my favorite service. It helps me out almost always, and it helps reduce the file size without losing quality. By at least it's not noticeable.
But I want to warn you right away that this does not mean that any size will be reduced by 5 times. How lucky. It all depends on various factors.
Well, for those who are not familiar with this service, I say - you can make no more than two transactions per hour. This is a limitation of the free version. But if you need to do more operations, then the price for an unlimited monthly lop will be simply ridiculous for you.
PDF Compressor
Another pretty good online service that has proven itself well.
Of course, the main disadvantage of this service is that it cannot work with very large files. When I tried to download previous file at 147 MB, then I got an error about the size being exceeded.
PDF2Go
Also a very cool service that helped me out a couple of times. I didn't have any complaints while working with him.
As you can see, this document has been compressed even more powerfully than in the first case. Not even 5, but 20 times. Of course, if you don’t particularly need such a small document, then you can set the quality to better, for example 150 or 300 dpi.
I talked more clearly about the three above services in this video.
PDFio
Well, the last thing for today I would like to consider is the Pdfio service.
But sometimes this service may give you a message that our file is already compressed incredibly well and will not further reduce its weight. This is the main disadvantage. Therefore, I would not recommend that you use this thing first.
Programs for working with PDF files
Well, now let's talk about individual applications, which you will have to install. Of course, not everyone likes it, but the program will always be with you, even if the Internet is turned off.
Adobe Acrobat
Let's start with official application from Adobe, which is the creator of the PDF format itself and is therefore completely aimed at working with it.
- In order to compress a PDF file as much as possible, enter the program itself and open the document whose weight you want to reduce. To do this, click on the menu “File” - “Open”.
- Now click on the "File" menu again, but now select the option "Save as different" — "Reduced PDF File".
After this, you will receive a reduced size document. But Adobe Acrobat has one more feature. You can choose "Optimized PDF File".
The difference between these two functions is that here you can adjust various settings, so that you can see for yourself what you can sacrifice and what you can sacrifice to a lesser extent. For example, you can reduce the quality, remove active links from the document, which also affect the weight, optimize for quick view online.
You can even apply custom downsampling for color and monochrome images(forced reduction in the number of pixels). Thus, by lowering the quality of graphics in Adobe Acrobat, we also reduce the size.
Naturally, this is the most convenient way. True, its disadvantage is that you need to install a special paid program. Although, who am I kidding? More than 95 percent of our users (and even more) do not purchase a license. But in fact, the program can be downloaded from the official website and used for free for 7 days.
CutePDF
This is not really a program, but rather an add-on with which you can save a PDF file from Adobe Acrobat Reader, in which by default this function not available. If you still don’t have an Adobe reader, download it for free from Adobe website. Just be careful, as the installer imposes McAfee antivirus. Uncheck all boxes.
First you need to download for free CutePDF Writer from the official website, and then run the installer. Just don't try to find the program, it won't be there. Now follow the instructions carefully.
This add-on is pretty good considering that it's free. But of all the options I have proposed, I like it the least. The fact is that in this way it will not always help you compress a PDF file to minimum size. Sometimes it turns out that the volume, on the contrary, also increases, especially if it initially takes up less than 1 or 2 megabytes.
Archiving
Well, perhaps I’ll tell you about the most old-fashioned way, which helped us out at a time when there were no converters or online services. Many people forget that a file can be compressed using any archiver, for example using the free 7-zip.
If you do not have the 7-zip archiver, then you can download it from here, and then install it as a regular program.
In addition, many email clients cannot forward large files. But the archiver can split one document into several parts, which can be sent by mail and put together by regular extraction.
I just tried to reduce a file that weighs 420 kb, and in the end I ended up with an archive of less than 300 kb. That is, archiving copes well even with small volumes and after so many years, it does not lose its relevance. Naturally, this method is relevant for sending or sending by mail. And after the recipient receives the archive, he will unpack it and it will be in its original form.
You can read more about working with archivers.
Why do you need to reduce the size of documents?
Typically, these actions are carried out in three cases:
- For release disk space. You have seen for yourself how much space can be freed up.
- For forwarding. Many sites, programs and email clients do not accept large volumes for sending and are limited in some way maximum size. Compression can help us with this.
- Speed. The larger the document, the longer it takes to open. Sometimes, if the computer is weak, this can even lead to freezing.

PDF files are quite in demand today, but they are often too large size, that is, they take up a lot of space. If you are not satisfied with the size of the document, you can reduce it in several ways.
You can reduce the size of a PDF file using a special converting program. There are quite a few such services; let’s look at the example of the free program PrimoPDF. Download the service to your computer. It will install a PDF printer on your system that will convert the files. You can also use the CutePDF program. Once you install it on your computer, there will be a print function that allows you to save files in PDF format. To begin, open the PDF document in the reader you are using. Select File, Print from the menu. Specify a converter (for example, PrimoPDF) as the printing device.
The PDF file size can be large for two reasons:
- high quality of documents, for example, a high resolution was selected when scanning;
- a large number of pages in a document, while sometimes only one or a few pages are needed from the entire document.
How to save a single page from a multi-page PDF file
We will use the resource smallpdf.com. Upload your document to the site and select the pages that should be in the final document. The selection can be made using the mouse or simply pointing required numbers pages. Then click the “Split PDF” button and download the file with the result. This way you can remove one page and also leave one page in the document.
You can also just print required pages from the document on virtual PDF printer How to do this is described in detail.
How to reduce the size of a PDF file
Some people try to compress PDF files with archivers (an excellent article about that), but this does not give a serious result, since any images are almost not compressed, so you need to act differently - reduce the quality of the documents.
It is better to use the same site smallpdf.com for compression. Upload your document and click "Compress PDF". In most cases, the size of the original document will be reduced very significantly.
Sometimes the size can decrease several times, while the quality, of course, will deteriorate, but it is completely uncritical.

Question about reducing file size in pdf format often put active user computer. This is due to the large weight of the scanned images. Because of this, the document takes up hundreds of megabytes on disk. Let's look at the problem in more detail.
Using Adobe Reader
You can reduce the document size using the free version Adobe programs Acrobat Reader. The compression function is only available at checkout paid subscription. The utility is installed without any problems, so let’s get straight to work.From home menu go to the “File” tab. Click on “Open” and select the document. IN in this example We will use a textbook weighing 69.9 MB. It consists entirely of scanned pages of the printed publication. You can also open a document by clicking on it in file manager. Go to the menu shown in the screenshot.
Leave the default values in the called window. Select a location to save the compressed pdf. The example file now weighs 33.3 MB. The compression was carried out for about two minutes. The quality of the images has deteriorated. This may not be noticeable on a website or computer. However, after printing, the illustrations will be fuzzy or completely blurry. Disadvantage of this method: no flexible settings for the advanced user.
If installation is required additional parameters, then the optimizer will help. Open the document we need. Click on the button shown in the illustration below.
There are few settings, but they look difficult to master. Let's define the main ones. They are located in the left menu “Images”. Downsampling determines the resolution of images. To the right of the parameter you can set ppi (pixels per inch). Highly not recommended for printing. It is recommended when placing illustrations on the site. Below you can set the compression type. ZIP is used for simple images with a predominance of one color. JPEG - for any images. Its improved version is JPEG2000.
After setting, select a location to save the file. Let's compare the quality of the optimized document and the original. Left - source file, on the right - compressed.
Changes in quality are invisible even when the image is enlarged three times.
Using third party software
For the role free analogue PDF Compressor will do.
The intuitive interface and light weight of the program will appeal to any user. In the upper left part of the window, you must click the “Add Files” button to open the document. You can also drag the file directly into the program's work area.
To optimize, click “Start Compression”. The button is located at the top center. First you need to set the compression parameters by clicking the “Compression Settings” button.
After opening the settings menu, you will be notified about purchasing a license. She is needed for fine tuning compression. Click “Continue” and check the boxes in the “Compression” and “Optimization” tabs. Close the window and click “Start Compression”.
During the compression process, the weight of the example textbook decreased from 69.9 MB to 56.9 MB. Let's compare the quality. On the left is the document before optimization, on the right is after.
The result is worse than Adobe Acrobat Reader. Now in compressed file distortion is noticeable. The advantage of the program is that you can compress the file absolutely free. As a result - worse quality and larger size. The utility logo is also added to the first page.
Using WinRAR
WinRAR - free program with the possibility of purchasing a license. Designed to place files in an archive and then compress them. The quality does not change. The original can be retrieved from the archive at any time.IN work area utilities shown file system your computer. Select the folder to create the archive. Click on “Add”. The button is on the left top corner. Here is the archive settings menu.
We are interested in the “Compression method” drop-down list in the “General” tab.
Their names speak for themselves. High-speed is less time-consuming and also has a low compression ratio. Maximum has the opposite characteristics.
Documents are added from the “Files” tab.
The file from the example was compressed in a few seconds. The file weight has changed from 69.9 MB to 68.3 MB. Conclusion: WinRAR does not work well with pdf files. The advantage of the program is that the original is preserved unchanged.
Using the online service ILovePdf
A convenient solution is web services for working with pdf files. ILovePdf can not only edit the contents of a file, but also reduce its size.
We start by clicking the big red “Select” button PDF file s". An explorer will open where we specify the path to the pdf document.
After selecting it below, the compression settings will appear. They don't need any comments. Let's leave the recommended parameters. At the very bottom there is a “Compress PDF” button. Let's click on it.
After the compression process we get to new page and press the big red button again.
In the screenshot above we were also informed about changes in document weight. Instead of 69.9 MB, the textbook now weighs 55.9 MB. The result is similar to the result PDF applications Compressor. The difference is that you don’t need to download or install anything. Let's compare the quality. On the left is the optimized document, on the right is the original.
A slight loss of quality is noticeable; it does not affect the perception of information.
Using the SmallPdf online service
This service allows you to download files from Google Drive or DropBox. From a computer, documents are sent through Explorer or by dragging a file into a browser window.
Click on the big red button. To reduce the file size in pdf format, you don't need to click anything. It happens immediately after loading. Then download the document by clicking on the “Download file” button.
From the service, the document can be sent to Google Drive or DropBox (adjacent buttons). The illustration shows the volume of the compressed document. The file size has changed from 69.9 MB to 59.2 MB. Slightly more than the previous service. Let's check the quality. Left - compressed pdf, on the right is the original.
SmallPdf was able to compress the file with virtually no loss of quality. The downside of the service is the lack of compression settings.
To conclude, archivers do not work well with PDF documents, A best method compression are online services and standard tool Adobe.
