Compress PDF files into one online. Compress PDF files
Nowadays, 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 downloading 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 desired size so that you can then use it for any purpose, such as sending 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
The Cute PDF program replaces a 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
Until recently, the PDF Compressor program 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
Adobe Reader Pro is a paid program, 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.
This is how you can reduce the size of a PDF file by one and a half to two times in three simple steps. This occurs due to the fact that the DOC document is saved as 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, after the trial period expires, 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.
In this tutorial we will learn how to compress a PDF file in various ways and with different quality (respectively different sizes PDF file)
Our task: reduce the size of an existing PDF file in order to send it by mail or if we simply need a smaller document size.
What we have in stock: the actual PDF files themselves or the file that needs to be reduced in size.
What we get at the end:
In our case, I suggest using online service ami for working with PDF files (i.e. all manipulations with PDF files will take place on the websites of the services we need).
From the large abundance of services and sites, I would recommend 2 of them, with the help of which we will reduce our PDF files to a minimum size with maximum compression or to “decent” compression but while maintaining the normal quality of photos in the PDF document.
So, I present 2 services for working with PDF files: and . In principle, one service would be enough (SMALLPDF.COM), but the PDF-DOCS.RU service has something that I will talk about a little later in this lesson;)
SMALLPDF.COM
Let's start with the SMALLPDF.COM service. By clicking on the link above we will see something like this:
This service has an intuitive interface, in my opinion, it won’t be difficult to figure it out, and you won’t be able to get lost in the functions. Therefore, in our case, this is an excellent solution to our mini-problem.
Let’s say we have a “compress PDF” folder and it contains all the files or one PDF file that needs to be reduced in size (I have 1 PDF file in the folder):
In order to compress the required PDF file, click the “Select file” button:
After selecting the PDF file we need, the file selection window will close and the service will begin manipulating the PDF file. The next thing we will see is the process of preparing and compressing the PDF file:
After passing the “100% Loading” stage, the page will refresh and we will see a block with the result of compressing our PDF file “big_file.pdf”:
From this data we learn that our original file “big_file.pdf” is compressed by 71% ( good result) and that now it “weighs” 2.84 MB, and was originally 10.14 MB. Below we are offered a link to download the already modified file:
Click “Download PDF” and the download of the compressed PDF file will begin:
Finally, in our “compress PDF” folder there are 2 files - an uncompressed file “big_file.pdf” and a compressed PDF file “small_file.pdf”:
With this compression service PDF files“SMALLPDF.COM” lesson is completed, let’s move on to the next service with its distinctive capabilities “PDF-DOCS.RU”.
PDF-DOCS.RU
So it goes to . At the time of writing this lesson « PDF Compression files" the main page of this service looked something like this:
Why did I choose this resource to solve our problem: in this service we can achieve higher compression ratio of PDF file compared to SMALLPDF.COM, but the quality of photos and images in the final PDF file (compressed) will be noticeably worse accordingly.
Let's start using the service. What we have at the initial stage: 1 PDF file in “raw”, uncompressed form:
First, we need to indicate to the service the PDF file that we want to compress. Click on the “Select file” button:
As a result of this, a new window will open in which we will indicate the path to the PDF file. In our case, this is the “compress PDF” folder and the file located in it “big_file.pdf”. Next, we need to set the compression level of the PDF file; for this, there is a special field in the “PDF-DOCS.RU” service:
We click on this field (I highlighted it in the figure above), we are asked to choose from three options PDF file compression ratio:
In our case (for maximum PDF compression) we use the “best compression” item. Now all parameters for compression are configured, click the “Forward!” button. and the service will begin downloading our source file and compressing it:
After clicking the button, the service will begin its work and a message will appear while the work is being completed:
After some time, after the “PDF-DOCS.RU” service has completed all necessary work above the compression of the PDF file, we are informed that the compression has been successfully completed:
Based on the data presented, we see that our compressed PDF file now weighs only 1.7 MB. This, in my opinion, is a very good result in terms of the quality of the drawings in the PDF file.
Now we need to download our compressed PDF file. To do this, click on the link below in the “Download file:” field. In our case, the link to the file will be called “new-314_big_file.pdf”, click on this link to download the file:
Clicking this link will begin the process of downloading the PDF file. In some cases, depending on the browser and settings you are using, clicking on the download link may cause it to open in the browser. If the file opens in a browser, simply save it to your computer.
As a result of our manipulations to compress the PDF file, we have 2 PDF files in the “compress PDF” folder:
As we can see, the source file weighs only 1.7 MB, which is very convenient for sending by email or uploading to a server.

You will need
- - Adobe Image Ready or any other program that supports editing animated images in gif format.
Instructions
