Compress PDF online - the best tools

2pdf.com.

2pdf.com is a comprehensive tool containing a set of utilities for processing PDF files. You can compress, merge, convert and perform other actions available in the menu:

The interface is multilingual, which is already a good thing. Obviously, to start the process you need to click on the red button to select or drag and drop items from your computer to the work area of the site.

After uploading to the server it is necessary to specify the degree of compression. For each mode there is an explanation. We will test the standard parameters to get a good quality. If you need to convert without loss, select "Low":

When the procedure is complete, it shows us how much the weight of the document has decreased by percent and immediately offers to save it to the PC. In this case the size has changed almost three times - to 279 Kb. The text remained readable, images became slightly grainy, but not much worse than the original.

If you want to compress PDF online by 5 times, you should resort to the "Maximum" compression.

SmallPDF

The appearance of the site is slightly different, but the operating principle is similar to the previous service. It is impossible to get confused in the management.

After a few seconds you will see the totals, and under them a few buttons to download, upload to the "cloud". Alas, you can't choose the compression level. As you can see, we got a file weighing 288 Kb.

As for "readability", it's quite high, though the pictures have some blurring around the edges.

SodaPDF

Quite a functional solution that offers a lot of tools. But let's sort out what's inside the pretty package.

Slightly annoying popup ads, but it is not critical. We download the file, indicate the degree and at the end of processing, we are offered to specify the e-mail to send the object. But it is better to choose below to view and download in the browser.

Alas, the size of the document is not very reduced - 754 KB. And the quality of images has suffered greatly.

Among the pluses of the service is the availability of an extension for Google Chrome, to get faster access to the toolkit Soda:

PDFcompressor - the best way to compress PDF online

Among the advantages - the ability to process multiple files simultaneously (no more than 20). Then you can download them separately or together, as an archive in one file:

The final size was 317 Kb. But I was very pleased with the quality. Let the weight and more than in the first two services, but otherwise all just great.

JinaPDF

The solution is in English - this is a minus. But there are more than two dozen functions for converting different types of documents. This is a plus. I won't show any screenshots, but I'll share the not quite outstanding figures right away - 381Kb.

PDF2Go.

This is where it gets interesting. Many modes are available, allowing you to compress PDF online for free without loss of quality, or compress the data as much as possible to minimize weight.

Leaving the default settings (Screen, high quality), I got an item with a weight of 457Kb. Wrong coat!

CleverPDF

A simple looking resource that has an interesting feature. After loading the data, you can specify the compression value from 1 to 100 (1-bad quality, 100 - high quality) in the parameters, in addition to the standard patterns:

Online converter works quickly and for free, and the report on the procedure is as follows: tried several settings, but even at the "Maximum" degree of compression, the file took about 700 KB. That's why I can't recommend this site. But you may like it.

Conclusions

At first I thought it would be difficult to make a decision, all resources will be almost at the same level. But of all the options I considered, PDFcompressor is the clear leader.
