Questions
Something missing? Send feedback →Are my files uploaded?
No. Every tool works on your phone, and your PDFs and photos never leave it.
Is Sign a legal digital signature?
No. It places a picture of your signature on the page, like signing on paper. It isn't a certified digital signature: there is no certificate and no tamper-proofing.
Can I use a password-protected PDF?
Yes, if you know the password. Unlock it first with the Password tool, which saves an unlocked copy, then use any other tool on that copy.
Why didn't my PDF get smaller?
Compress shrinks the pictures inside a PDF, so scanned and photo-heavy PDFs shrink a lot and text-only PDFs barely shrink. If the result isn't smaller, the app keeps your original and saves nothing.
