Common questions

What if my PDF cannot get under 500 KB?

Very long or photo-heavy PDFs sometimes cannot. We tell you the smallest size we reached. Splitting the PDF, or scanning in black and white, usually gets it under 500 KB.

Will the portal accept it as under 500 KB?

Yes. We aim under 5,00,000 bytes, so it passes whether the portal counts 1 KB as 1,000 or 1,024 bytes.

Is Compress PDF free?

Yes. Up to 50 tasks a day per visitor, with no sign-up and no watermark on your files.

Are my files safe?

Files are processed on servers in India, checked for viruses, and deleted automatically after one hour. You can also delete them yourself right after downloading.

Does it work on my phone?

Yes. It works in any modern browser on Android, iPhone and computers, with nothing to install.
