Sign a document without printing it
The form came as a PDF. It needs your signature. The old routine: print it, sign it, scan it back, and hope the scanner doesn’t cut off the corner. Skip all that. Type or draw your signature here, drop it on the page, and download the signed file. Two minutes, no printer.
You get two ways to sign. Type your name and it renders in a handwriting-style script font, the closest thing to a real signature without a pen. Or switch to Draw and sign with your mouse, trackpad, or finger on a touchscreen, the way you’d scribble on a delivery pad. Either one becomes a clean signature image stamped onto your PDF.
Placing it where it belongs
Most signatures live in one of six spots, so that’s what you pick from: top or bottom, left, center, or right. Bottom right is the default because that’s where signature lines usually sit.
Then choose which pages get it. Just the last page (the usual case for a contract), the first page, or every page if you’re initialing a whole document. Hit Sign PDF and the signature lands at a sensible size with a bit of margin from the edge, so it doesn’t crowd the text.
It all happens on your device
Your PDF never gets uploaded. The whole thing runs in your browser with pdf-lib, so a sensitive contract or a tax form stays on your computer from start to finish. The signed copy downloads with -signed added to the filename, and the original is left untouched.
That local-only approach matters for documents you’d never want sitting on a stranger’s server. NDAs, offer letters, medical forms, anything with real information on it.
An honest note on what this is
This adds a visible signature to your PDF. It is not a cryptographic digital signature or a certified e-signature service with identity verification and a tamper-evident audit trail. For most everyday forms, permission slips, and internal documents, a visible signature is exactly what’s asked for and it’s accepted. If you’re closing on a house or signing something that legally requires a certified e-signature platform, use a dedicated service like that instead.
Common questions
Does my PDF get uploaded to a server? No. The signature is added in your browser with pdf-lib. The file stays on your device, and only you ever see it.
Can I draw my signature instead of typing? Yes. Switch to the Draw tab and sign with your mouse, trackpad, or finger. On a phone or tablet it feels closest to real signing. There’s a Clear button if you want a redo.
Is this a legally binding e-signature? It adds a visible signature, which many forms accept. It is not a certified digital signature with an audit trail. For anything that legally demands certified e-signatures, use a dedicated platform.
Can I put the signature on every page? Yes. Set “Apply to” to Every page. Handy when a document asks you to initial each page rather than sign once at the end.
Will it cover up the text underneath? The signature sits on top at a fixed size with a margin from the edge. Pick the corner that lines up with the signature field so it lands on the blank space, not the body text.
What if my PDF is password-protected? It can open many protected PDFs to add the signature, but a fully encrypted file may not load. Remove the password first, then sign.
