5 Free PDF Compressor Online (Updated)
Today, PDF files have become a popular and widely used file format. We always use PDF files for work and study. PDF files are reliable and compatible, and can be used across multiple platforms. Its characteristics make it a most suitable file format for transmission and sharing via email or online. However, files that are too large cannot be smoothly transferred and shared, because our emails generally have file size restrictions, and files that are too large are not conducive to sharing as it takes a lot of time for you and your friends to send and receive files.
To this end, we need a PDF compressor to optimally compress our PDF files without affecting the output quality so that we can share them with others. To solve this question, we have listed 5 online PDF compressors for convenience to compress files easily and quickly. Of course, we don't need to download any plug-ins and software to occupy our limited storage space.
#1. EasePDF (Recommended)
EasePDF Online PDF Compressor is an excellent online PDF compressor. Its rich and powerful features will not let you down. When we compress a file, we always value the output quality of the file.

#4. Foxit
Foxit Online Compressor is a free tool that I found accidentally. In fact, Foxit does not mainly work for online PDF tools, but for offline software. Therefore, the number of online tools provided by Foxit is limited, only a total of 7 tools including Compress PDF, but it has basically included the PDF tools that we usually use.
Its interface is simple. You will only see two buttons, one is Select your file and one is Compress now. For users who urgently need to compress PDF files, the simpler, the better. Unfortunately, only one file can be compressed at a time.
If you are interested, you can apply for a 14-day free trial of the desktop version and you will find that Compress PDF can also be very diverse. With Foxit, you can reduce PDF without losing quality, edit documents, create PDF files and use OCR technology.
