A PDF signature tool for every document
Whether you need to sign a PDF for a new hire's contract, sign a PDF doc for a client, or create a digital signature for an internal policy, Sign Pdf handles it. Draw your signature, type it, or upload one — then place it anywhere in the PDF and finish. It works as a lightweight PDF editor for signature fields, initials, dates and text, so you never need separate software to prepare a document before signing it.
Draw, type or upload your signature
Add a signature to any PDF your way — sketch it with your mouse, type your name in a signature font, or upload an image. A true esign PDF experience, no scanner needed.
Signature, initials, date & text fields
Place exactly the fields you need on your PDF doc, assign each one to a signer, resize and reposition them with a drag.
Reusable templates
Save a field layout once and apply it to every new PDF document of that type in a single click.
PDF editor & signer — desktop or browser
Sign PDF documents fully offline with the Windows app, or sign a PDF online from any browser with the web app — your choice.
Full audit trail
Every upload, field change and digital signature is logged, so you always know who signed the PDF and when.
