Good day!
PDF files seem to be good for everyone, but they have one cornerstone ... The fact is that the size of some PDF files is far from the "ideal", often, when they weigh even 100÷500 MB, sometimes it reaches 1 GB! Moreover, such a file size is far from always justified: i.e. it does not have some very high-precision graphics that take up so much space.
Of course, when dealing with such a size, it is difficult to transfer it to other PCs, tablets, phones (for example, the phone simply may not have enough memory for a dozen of these files!) .
In such cases, you can "somewhat" reduce the size of the PDF by compressing it. By the way, you can compress different ways. Actually, this is what today's article will be about ...
By the way! If you remove some pages from a PDF document, then you can reduce its size due to this. If this option suits you, then I recommend this note:
Method number 1: archiving
Perhaps the most simple and obvious is to add PDF files to the archive. Thus, sometimes, it is possible to significantly reduce the size they occupy. In addition, one archive file is much faster and more convenient to copy from one PC to another. (rather than a dozen or even a hundred PDFs) .
Addition! The best free archivers for Windows -
To send a file to the archive - just 1-2 mouse clicks are enough. For example, in such a popular archiver as 7-Zip (you can also find it at the link above) : just right-click on the file and select from the menu that appears "Add to archive..." . See screenshot below.
Actually, my file was compressed almost 3 times! An example is below.
Advantages of the method:
- after unpacking the archive, the PDF file does not lose its quality;
- ZIP archive formats can open most modern ;
- one archive file (in which there are hundreds of PDFs) is copied much faster than doing it with the same files without adding them to the archive.
The disadvantages of the method:
- to open a file, you need to extract it from the archive (and not all PCs/phones/tablets may have the required archiver installed);
- not all files compress equally well: one can be compressed very decently, another - by 0.5%...
- when choosing some archive formats, it may take a long time to pack the files.
Method #2: Compress with Downscaling (DPI)
DPI is the number of dots per inch. The more dots per inch - the higher the quality of the displayed image (and the more the file weighs). Naturally, when re-saving a PDF file, you can specify a new number of dots per inch (DPI) and thereby reduce the file size (along with its quality).
However, I’ll note right away that it’s far from always that with a decrease in DPI, the quality of the picture worsens (in many cases you won’t notice a difference by eye!).
It is possible to do such a procedure in many programs : Adobe Acrobat (do not confuse with Adobe Reader) , Fine Reader, Cute PDF Writer, Libre Office, etc. Here are a couple of free examples...
1) LibreOffice ()
Good and free office suite (I have previously recommended it as an alternative to MS Office). It has a DRAW program in its arsenal, which can easily and naturally make changes to PDF (including changing DPI). Let's take a closer look...
To launch DRAW - launch Libre Office, and select "DRAW Drawing" from the menu.
A window will open with many options for saving. Here you can change the compression quality, resolution (DPI) and other parameters. In general, I have highlighted the most necessary on the screen below.
After setting the parameters - click the export button to create a new file.
Fast, simple and easy! Is not it?
2) CutePDF Writer ()
This free program, after installation, "creates" a separate special line when printing a document (with the necessary properties for compression) ...
Those. install it, then open some PDF file, say, in Adobe Reader (you can also use any other program for PDF reader) and press "Print" (combination Ctrl + P).
Then choose instead of a real printer the line " CutePDF Writer", and open its "Properties".
Properties of CutePDF Writer
After you need to open the print quality tab and go to "Advanced".
Here you can set the print quality in DPI (and other parameters).
NOTE.
By the way, you need to install both files that are available on the official website of the program!
Pros of the method:
- do not lose compatibility (the file then remains the same PDF);
- the operation is quite fast;
- the operation "by changing the DPI" can be carried out by dozens of different programs.
Cons of the method:
- in some cases, the quality drops a lot (for example, if you are dealing with schemes and high-quality portfolios - most likely, this option won't fit).
Method number 3: converting to DjVU format
The DjVU format, on average, provides stronger compression than PDF. And I must admit that DjVU is one of the few formats that really competes with it.
To convert from PDF to DjVU, in my opinion, it is most preferable to use one small utility - PdfToDjvuGUI .
PdfToDjvuGUI
Of. site: http://www.trustfm.net/software/utilities/PdfToDjvuGUI.php
Note: Please note that the utility sometimes incorrectly reads the "names" of files written in Russian.
PDF to DjVU - a small utility
Using it is very simple: just add desired file(Add PDF), set the settings (you can not touch anything) and click the button "Generate DjVU". A "black" window should appear for a while, after which the program will inform you that the file has been converted.
By the way, Djvu file the program will place it in the same folder where the original PDF was located. See the screenshot below as an example. Without changing the quality (and the program allows you to change the DPI), we managed to reduce the space occupied by the file by almost 2 times!
PS
Below are a few more online servicesthat can do a similar conversion operation.
Advantages of the method:
- maximum file compression (i.e. saving disk space!);
- the file can be immediately opened in the reader, just as you do with PDF (i.e. it is not an archive).
The disadvantages of the method:
- large files require significant time to convert;
- quality may be "lost" during conversion (so check important graphics manually to see how they are compressed);
- DjVU format is supported by fewer programs than PDF.
Method #4: Using Online Tools
Great site for fast compression and conversion from one format to another. Files up to 20-30 Mb in size are processed literally within 10-15 seconds! The service does not touch the document markup, links, menus, and other elements. Compression occurs due to graphics (that is, the PDI parameter).
Another one-stop service for fast PDF conversion in DjVU, or for PDF compression without changing the format. The result can not only be downloaded to your PC, but also immediately sent to a cloud drive: Google drive Dropbox...
There are 3 compression levels available on the service: minimum, normal and extreme. It works very fast, it processes files up to 3-040 MB in 5-10 seconds. (at least that was the case with my dozen test files) .
The files have been compressed // Service "I love DPF"
I also note that on this service you can split a PDF file into several parts, convert it to other formats, merge several PDFs, etc. In general, a rather multifunctional service, I recommend it for review!
Advantages:
- there is no need to install any programs on your computer;
- services can be used even from mobile devices;
- as a rule, compression of small files on services is faster.
Flaws:
- confidentiality (I think not everyone will dare to send some of their documents to an unfamiliar service);
- the need to upload / download files to the service (if the Internet is not very fast and there are a lot of files, this will turn into a "headache").
Suggestions on the subject are welcome...
Have you created a PDF document, but it is very large? Are there too many documents on the media and taking up a lot of memory? Need to send a message, but the document is too large and takes a long time to load, or is it not possible at all due to the size of the document?
Today this problem will be solved, several solutions will be considered. Most of the methods mentioned below are possible only in the shell of the software - "Acrobat DC" from Adobe, which requires installation on a computer. This software paid, but it is possible to use the test version for 30 days. But other options will also be considered, ie without using Adobe's "Acrobat DC" software.
1. How to reduce the size of a pdf file using online services
If there is no desire to download and install anything, there is a great opportunity to compress a PDF file online. Compressing documents online is convenient, reliable and fast. There are many services on the Internet that can help you reduce the memory footprint of a PDF file for free. Below are some of them:
1.1. SmallPDF - online .pdf compression service
1. Open the desired file that you want to compress using Acrobat.
3. In the next "PDF Optimization" window, you need to select the "Estimate Space Usage" option to know which parts of the document take up the most space in the document. The calculation is carried out in percentages and bytes. Taking into account the information on the assessment of the occupied space, and making a conclusion about what needs to be compressed and what is not worth it, you can proceed to direct file compression. To do this, in the upper left part of the window, with the left mouse button, you need to select the parameter items, and in the upper right part, you need to change the settings themselves. After the end of all necessary settings the file should be saved.
The use and distribution of unlicensed software may create additional difficulties in the operation of your PC, beware of such programs and sites. Happy using!
