Can I unlock a PDF on my phone?

Yes. OneConvertly works in any modern mobile browser. Upload the PDF, enter the password, and download the unlocked copy.

Is there a file size limit?

Files up to 200MB are supported. Processing speed depends on your device since decryption runs locally in the browser.

Does unlocking change the PDF content?
