When you need this

  • A scanned rental application is 38 MB and the landlord's mailbox rejects it.
  • A presentation handout full of photos should load quickly on a phone.

Frequently asked questions

What files can I use here?

As many files at once as you like.

What do I get back?

You get PDF.

Does the file lose quality?

Pages are rewritten and their images compressed again. Text stays sharp, photographs inside the document lose a little.

When does it not work?

Password-protected files cannot be opened.

Does the text stay searchable?

Yes, and compressing keeps it that way too: by default only the embedded photos are recompressed, while text, fonts and layout stay untouched. Merging, splitting and adding images move the pages as they are. Only the second compression method redraws every page as an image — then the text becomes part of the picture, and the tool says so before you start.

Can password-protected PDFs be opened?

No. A PDF locked with a password cannot be read in the browser, and the tool says so rather than producing an empty document. Remove the protection in the program that created the file first.
