Printing a document just to sign it and scan it back in is a step most paperwork doesn't actually require anymore — a signature placed directly on the PDF gets the same visual result without leaving your screen.
A form or agreement needs a signature today
Skip the print-sign-scan loop entirely by drawing or typing a signature straight onto the PDF.
The same signature is needed across multiple pages
A signature created once can be placed on every page of a multi-page document without redrawing it each time.
A quick visual signature is all that's needed
For everyday internal sign-offs and casual agreements, a drawn or typed signature on the page is often enough — it isn't a certified e-signature.
How it works
Upload
Add the PDF you need to sign. Nothing is sent anywhere at this step.
Create a signature
Draw it with your mouse, finger, or stylus, type it, or upload an image of it.
Place
Drag and resize the signature on any page, scrolling through the document to reposition it as needed.
Download
Save the signed PDF with the signature placed directly on the page.
Key features
Draw, type, or upload
Create a signature the way that suits you — freehand, typed text, or an uploaded image.
Reusable across pages
Place the same signature on multiple pages without recreating it each time.
Drag and resize
Position and size the signature freely on the page rather than being locked to a fixed spot.
Runs in your browser
The signature is applied to the PDF locally — your document never leaves your device.
No sign-up
Open the tool and start signing — no account, no email, no waiting.
Free
Sign as many documents as you need, with no watermark added to the result.
Who uses Sign PDF?
Freelancers

Frequently asked questions
Is this a legally binding e-signature service?
No — this is a simple visual signature tool for adding a drawn signature to a document, not a certified e-signature platform with identity verification or audit trails.
Can I use a touchscreen or trackpad to sign?
Yes, the signature pad works with mouse, touchscreen, and stylus input.
Is my document uploaded to sign it?
No. The signature is drawn and placed onto the PDF entirely in your browser.
