Signing on Mobile, Done Right
The phone is where documents arrive and where it is most natural to sign β a finger on a touchscreen makes a better signature than a mouse ever will. Yet most mobile signing means installing an app or uploading the file to a service. This tool runs in the mobile browser: open the page, draw your signature, tap where it should go on the page preview, and save.
You can also type your name in a signature font or upload a photo of your real signature. Whichever you choose, the mark is embedded into the PDF on the phone itself, so a signed contract or form never has to be uploaded anywhere.
Private, No App Needed
Everything β drawing, placing and embedding the signature β happens in your mobile browser with pdf-lib. There is no upload and no account; the signed file is built on your phone.
