The main reason why many people prefer these sites is that they work on almost every device and operating system.

Here’s what you need to do to compress a PDF file online:

There’re many free sites, but there’re also many alternatives, such as the PDF tool from Adobe, the company that invented these documents.
How to Compress PDF on Mac with Preview?
One of the most significant advantages of owning an Apple computer is the numerous free programs and tools with the operating system. Among them is Preview, a program that, from its name, only lets you view photos and documents but, in reality, is much more powerful.
With Preview, you can actually compress a PDF on Mac for free without installing any additional programs. Moreover, it’s the fastest and easiest way to reduce the file size:
- Open the PDF on your Mac by double-clicking on it
- Select the file and then export
- Select PDF in format input
- Click on the quartz filter field to open the drop-down menu
- Select ‘Reduce File Size’ and save the document to your desired folder
- A copy of the PDF will appear in the folder you selected with no loss of quality in a few seconds.
If you have an older version of macOS, the steps may vary slightly, in which case you can follow the official guide directly on the Apple website. You can also use third-party programs like PDFElement for Mac to provide tons of additional editing tools. But as long as you don’t need a specific feature, Preview does the job just fine.
Compress PDF on Windows PC
Unfortunately, Windows users can’t trade as quickly as Mac users and resort to third-party programs. Fortunately, the selection isn’t lacking at all; there’re many.
Among them, we recommend using Adobe and Free PDF Compressor. As we mentioned earlier, the first is the company that creates the PDFs. That’s why it’s among the best in its field but only accessible for the first 7-day trial. Then it would be best if you switched to a paid subscription. Free PDF Compressor, on the other hand, is entirely free and works well.
If you’re using other free programs, we recommend that you always protect your computer with an excellent antivirus to ensure the installation file is free of viruses.
One of the best free Adobe alternatives is Free PDF Compressor. Free as the name suggests, it’s a fast and easy-to-use program that does a great job. It is available for Windows; you can download it directly from the official website and install it without any problems.
After installing it on your PC, launch it to open the compression screen directly. First, click the ‘Browse’ button under PDF file and select the PDF you want to compress. Then select the target folder in the line below and the compression level in the ‘Settings’ section.
Here you have five different compression settings, the most effective. However, this comes down to the final document’s resolution at 72 dpi. Then there is the e-book setting, which is helpful for books and documents. The higher the dpi, the higher the resolution and the larger (less compressed) the final file.
At this point, click on compress and wait for the program to reduce the file size. You will find it in the folder we mentioned above when it is ready.
