SignFit opens your PDF in the browser, lets you place a signature, text and checkmarks, then flattens and downloads it — all on your device. No upload, no account, nothing stored on a server.
Drop in a form and type into it. SignFit detects existing PDF form fields and lets you place free text anywhere else the form needs it.
Draw with a mouse or finger, type your name in a signature font, or upload a PNG of your signature.

Yes — signing and filling one document at a time is free. Pro (one-time) adds a signature library, reusable templates, and batch signing.
Never. Turn off your network after the page loads and it still works.
