Frequently asked questions

Which level should I pick?

Strong suits most scanned forms, certificates and photo PDFs. Use Light if you need to keep text selectable, and Maximum to get under a strict upload limit.

Why can't I select text after Strong compression?

Strong and Maximum turn each page into a compressed image. That's what makes the file so much smaller.

How do I get my PDF under 100 KB or 200 KB?

Many application forms set limits like these. Try Maximum first. If it's still too big, use Split PDF to keep only the pages you need, then compress again.

It says the file couldn't be made smaller.

Some PDFs are already well compressed, usually text-only documents. Try a different level, or the file may already be as small as it can be.
