Your files are processed inside your browser. Nothing is uploaded to a server.
How to use PDF Compressor
- Add your PDF file.
- Choose a compression level.
- Press Compress PDF, compare the sizes and download the smaller file.
How this compressor works
Each page is turned into an optimised image and rebuilt into a new PDF. This gives large savings on scanned documents and photo-heavy files. Text in the result is no longer selectable, so keep the original if you need to copy text.
Which level should I pick?
- Recommended: a good balance, clear on screen and in print.
- Strong: much smaller, still readable.
- Maximum: smallest file, best for upload limits when quality matters less.
If the file does not get smaller
A PDF that is already optimised or mostly plain text may not shrink. The tool tells you when that happens, so you can keep the original.
