Highly compress the pdf file. Compress and reduce PDF files

In this lesson 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 services for working with PDF files (that is, 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 - not compressed file"big_file.pdf" and compressed PDF file "small_file.pdf":

With this service for compressing PDF files “SMALLPDF.COM” the 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"Compress PDF files" home page 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 via email or uploading to the server.

It’s probably not news to you that the pdf format is widely used in all areas of activity due to its “weight” and its image quality. Why did I focus on “weight”? Because usually this file weighs a lot due to the many colored, bulky and bright graphs and so on. Therefore, today we will look at the question: “how to reduce the size pdf file”, since most people have questions about this very issue. Some people even prefer to use other programs because of this problem. Compression pdf file ov is a process that requires the use of special software. To reduce the file size, you can use the following programs: Adobe Acrobat, using standard Windows compression. Adobe Acrobat can be downloaded from the developer's website.

How to compress a pdf file?

Method using Adobe Acrobat

In order to reduce a pdf file, open Adobe Acrobat, then click on the “File” - “Open” tab in the main menu - these actions give us the opportunity to open the file required for compression. Then repeat the steps “File” – “Open” – “Save as another” – “ Reduced PDF file size" In the window that appears, select the version compatibility setting and click “OK”; in order to apply the settings to several files, click “Apply for all”, to save you need to click “Save As”.

Method for reducing file size in Adobe Acrobat using PDF optimizer

As you noticed, Adobe Acrobat makes it possible to reduce the file size in a convenient way for us. First, you need to select the documents that need to be reduced in size. To do this, we need to click on the “File” – “Open” tab in the main menu. Then we repeat the same steps, then click on “Save as another” - “ Optimized PDF file" Then you need to adjust the settings to your taste and save the file by clicking on the “Save As” button.

Method for reducing the weight of a pdf file according to OS Windows standards

In order to achieve best quality And lightest weight, OS Windows developers strongly recommend using standard file reduction before starting work on it. This can be done by pressing right click mouse on the file you created – “Properties” – “General” – “Other” – then you need to check the box “Compress...”. This procedure takes no more than one minute and is one of the most effective.

Compressing PDF files is not as complicated a process as it might seem at first glance. There are a number of programs with which you can perform these actions easily and quickly. They will be discussed in this article.

Advanced PDF Compressor provides the user with the ability to reduce the size of the required PDF document. Here you can clearly see how much this file has been reduced. Also, thanks to Advanced PDF Compressor, you can convert images into one or more such documents, or group any number of PDF files into one. A significant difference from other similar programs is the ability to create profiles with different settings, which, in turn, simplifies its use by several people.

Free PDF Compressor

Free PDF Compressor is a free software tool that is only capable of reducing the size of a specified PDF document. For these purposes, there are several template settings that can be selected based on the required quality. Thus, the user is able to give the PDF file the quality of a screenshot, e-book, and also prepare it for color or black and white printing.

FILEminimizer PDF

FILEminimizer PDF is a simple and easy-to-use program that does an excellent job of compressing PDF files. For these purposes, the user is offered four template options. If none of them suits you, you can use the settings and set your level. In addition, it is the only product that provides the ability to export a compressed document directly to for later sending by email.

CutePDF Writer

CutePDF Writer is a free printer driver that is designed to convert any document into PDF format. In addition, the program is capable of compressing PDF files. To do this, go to the advanced printer settings and set the print quality to be lower than that of the original. Thus, the user will receive a PDF document with a significantly smaller size.

The article contains the best software tools with which you can significantly reduce the size of the required PDF document. Unfortunately, none of the programs reviewed have been translated into Russian, but despite this, working with them is very simple and convenient. All you have to do is decide which solution to use, because each has its own unique capabilities.

Why compress a PDF file at all? I understand, pictures, videos that weigh tens, if not hundreds of megabytes, the same music. They need to be squeezed. In fact, files also need to be compressed, because in some cases they can be more than a couple of kilobytes. This often applies to books and large articles with pictures.

Fast compress file pdf document can be sent by mail, where the downloaded file size is set to a fixed size. When uploading to your website or other resource where you want to save space. There are many options for why this should be done, so in the article I will reveal all the known methods.

In the article about PDF definition I wrote about its benefits. The format can be opened on any computer and operating system and the appearance of the document will not change. The only drawback is the size.

How to compress PDF online using services

Compressing a PDF document via the Internet is the most popular and convenient way. There are many services to carry out the process, which I will describe in this article. Well, let's go?

pdfcompressor.com

The resource may not be the best, but working with it is easy and convenient. To load a document into the resource window, just move it there, or click the button "Download" and select a file on disk. Suppose I take a book on computer architecture that is 19 MB in size. Now I’ll upload it to the site and see how efficiently it compresses the document.

As a result, the book shrank by 49%, almost doubled, which means its size is now 9.7 MB.

Compressing PDF format is not the only thing that can be done on the resource. It also converts images and ODT type to PDF format, PDF conversion to DOC format and vice versa, the same with HTML, PUB, ePub. The disadvantage of the service is that it is slow to upload a large file to the server, so you need to be patient and wait if you decide to compress the file to 100 MB.

ilovepdf.com

The next PDF compression option is the ilovepdf.com service. Also popular, but that’s not important to us, is it? You, as a user, are interested in the effectiveness of this service. We'll check it now.

Having visited the resource, you have two methods of uploading a file to the server - click the button "Select PDF file" or drag it there. I choose the same book about computer architecture weighing 19 MB. 3 compression options immediately appear in the window - low compression, recommended And extreme. Depending on the type you choose, the quality of the document will either not be affected or will suffer more. Let's try extreme compression.

We are waiting for the PDF file to download and the compression process to begin. According to my observations, loading occurs at a low level. Approximately 60-70 Kb/s, my Internet is not shit, which means this is a limitation of the service itself.

As a result, the document shrunk by 50%, as in the previous case and its size was 9.4 MB. We can conclude that ilovepdf.com and pdfcompressor.com do their job almost equally. It's up to you to choose which one is more convenient. By the way, the components of the document were not damaged, that is, images and text.

In addition to the ability to perform the process that we are currently implementing, the resource can do the following useful things:

• Merge and split PDF files;
• Compress PDF;
• Convert PDF to Word, PowerPoint, Excel, JPG and vice versa;
• Insert watermarks into the file;
• Remove security passwords;
• Flip the document at any angle;
• Uploading files from the Dropbox and Google Drive cloud.

Please note that an unregistered user can upload a file up to 160 MB; after registration, you can upload files up to 200 MB.

smallpdf.com

Almost no different from previous services, but who knows, maybe smallpdf.com can compress pdf better? This is what we will find out now.

I upload the book document in PDF format to the resource and wait for the process to complete. The result was almost identical to the previous ones - 9.6 MB.

Now the compressed file can be downloaded to your computer or saved to . By the way, the functionality of the service has the same capabilities as all other sites.

jinapdf.com

Right now, without further ado, I am uploading the book file to the jinapdf.com server. I hope that this compressor will be better than other options.

The result was much worse than the others: with 19 MB we were able to achieve compression of up to 17.4 MB. Therefore, I will not use this option.

Additional tools can be found on the website:

• Convert PDF format to Word, Text, JPG and vice versa;
• Convert image to text;
• Merge PDF;
• PDF extraction;
• PDF Splitting.

In short, nothing new and all services are eerily similar to each other.

pdfio.co

You can upload a document from a cloud computer or via a link, or by drag-and-drop. After downloading, wait a little and look at the result.

So, the beautiful and pleasant interface gave us the worst result - 18.2 MB. Probably worse could be the lack of any compression.

You can compress a pdf without losing quality, to do this you need to select “Low compression”, or slightly degrade the image quality by selecting the option “ High degree compression."

In addition to the “unique” functions that the resource has, you may have noticed the “Online text recognition” item. The top panel contains image compression options, various converters and converters from MP4 to GIF.

pdf.io

Very simple website with a big button "Select file" with which you need to select a PDF document. There are options for downloading from the cloud or via a link.

In this case, it was possible to compress the PDF by 37%, maybe someone will have a better result, I can’t say. Rather it depends on the document.

You can download the file to your computer or upload it to Dropbox or Google Drive.

pdf2go.com

Last hope guys. I move on to the last service on this list and voice my verdict. Then I'll move on to programs.

The result is 17.48 MB.

The conclusions are obvious, only the first two services from the list provide normal tools for compressing PDF files.

How to compress a PDF file using programs

Using programs is less convenient, since you need to find a worthwhile option, download and install. Luckily, I've put together a few options that are on par with their online service brethren.

Adobe Acrobat

Famous viewer PDF documents. For those who don’t know, you can use it to save a document at a reduced size. To do this, go to “File”, select “Save as Other” and click on the “Reduced PDF File” option. This feature is only available in the paid version.

The best way to view PDF is . I consider this the most convenient utility, but I did not find a compression function there.

Most effective way, compress a document of our format - run it in the online tools that I described above, and then compress it using an archiver, for example, .

Let's say I already have a compressed file. The same book in PDF format. I right-click on it to bring up the context menu and select the 7-ZIP > Add to archive option.

In the settings you set the same parameters as mine. You can play around, maybe you will achieve better results.

I achieved the following size after compression into the archive - 9.66 > 8.54. Not very much, but sometimes that's enough.

Results

We looked at a bunch of methods on how to compress PDF online or using programs. In fact, I did not consider some utility options here, since there is a lot of hassle with them. From all of the above, we have come to the conclusion that the most effective method compressions are:
