Frequently asked questions

How do I reduce the size of a PDF?

Drop your PDF into the compressor above. It is compressed automatically and you can download the smaller file straight away.

Is my PDF uploaded?

Yes — unlike our image tools, PDF compression runs on our server. Files are sent over HTTPS for processing; our image tools, by contrast, never upload anything.

Will compression reduce quality?

Text stays sharp. Embedded images are recompressed, which may slightly soften high-resolution photos.

Is it free?

Yes, with no watermark and no account needed.
