Edit & sign PDF

Draw, type or upload your signature, add text, dates, checkmarks and stamps, fill in form fields, and optionally add a digital certificate signature. Everything happens in your browser — your PDF never leaves your device.

Electronic signature

A drawn, typed or uploaded signature is a simple electronic signature — a picture of your signature placed on the page. It's fine for everyday forms and agreements.

Digital certificate signature

With your own .p12 / .pfx certificate, Morphio adds a cryptographic signature that PDF readers like Adobe Acrobat show as signed and that reveals any later change. It is as trustworthy as the certificate you use — Morphio does not issue certificates or add a trusted timestamp.
