Frequently asked questions

Can’t find your answer? Contact us

Is Compress PDF free?

Yes. Compressing PDFs on PDFixed is completely free, with no sign-up and no watermarks.

Are my files safe?

Your PDF is compressed right here in your browser. It is never uploaded to our servers, so nobody else can see it.

How much smaller will my PDF get?

It depends on what is inside. PDFs with photos or scanned pages often shrink by half or more. PDFs that are mostly text are usually small already, so they only get a little smaller.

Will compressing make my PDF blurry?

Text and drawings stay perfectly sharp. Only photos and scans are reduced. Pick “Light compression” if image quality matters most.

Can I compress a password-protected PDF?

Not yet. Remove the password first, or send the file to one of our experts and we’ll handle it for you.
