Sign a PDF
Draw your signature with a finger or a mouse, place it where it belongs and fill in the blanks. Everything happens on your device.
⚖️ This is not a digital certificate. It places a picture of your signature into the document — the same as printing, signing and scanning, but without the printer. Nothing here proves who signed or stops the file being changed afterwards.
🔒 Your PDF never leaves your device.

Frequently asked questions
Does the text stay searchable?
When merging, splitting or adding images, yes — the pages are moved as they are. Compressing is the exception: it redraws every page as an image, so the text becomes part of the picture and can no longer be selected or found.
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.
Are my files uploaded to a server?
No. The whole job runs inside your browser, on your own device. Your file never travels over the network, so there is nothing for us to store, read or lose.
Does it cost anything?
No. There is no account, no trial and no upload limit tied to a plan.
Does this work on a phone?
Yes, on Android and on iPhone. The browser does the work, so no app has to be installed.
How large can a file be?
The limit is your device's memory rather than a rule we set. Very large files work on a computer and can fail on an older phone.
