Free PDF Compressor

Reduce the file size of your PDF while keeping it usable. Choose a compression level based on whether you need smaller size or higher quality. Free, no sign-up, files deleted immediately.

Which compression level should I use?

"Screen" gives the smallest file size, best for email attachments or quick sharing. "Ebook" is a balanced default suitable for most uses. "Printer" keeps higher image quality with more modest size reduction, best if the PDF will be printed.

Is my file safe?

Files are processed on our server and deleted immediately after compression. Nothing is stored, shared, or used for any purpose other than completing your request.

Is it really free?

Yes — this tool is free to use with no sign-up required. Fair-use limits may apply to prevent abuse.
