Compress PDF: frequently asked questions

Is Compress PDF free to use?

Yes. Compress PDF is free to use in your browser with no signup required.

What files can I use with Compress PDF?

Compress PDF accepts PDF files. The maximum upload size is 50 MB per file.

Will the content of my document change?

Optimization tools keep the visible content of your pages. Compression may lower image resolution to save space, so choose a lighter level if image quality matters most.

What if my PDF is damaged or won't open?

Try the Repair PDF tool first. It rebuilds the internal structure of the file, after which other tools can usually process it normally.

Are my files safe?

Files are processed on demand for your request and working files are cleaned up automatically. We never look at your content, and we don't sell data.
