Sign a PDF
Draw your signature (or upload a photo of it), click where it goes, and download the signed document. A contract you're signing never leaves your device — which is exactly how it should be treated.
How it works
- Create your signature. Draw it with your mouse, finger or stylus — or upload a photo of your signature on white paper; the background becomes transparent automatically.
- Place it. Drop your PDF, click the spot where the signature belongs, drag to fine-tune, use the slider to resize. Repeat on as many pages as you need.
- Sign & download. The signature is embedded into the PDF itself and the signed file downloads instantly.
Frequently asked questions
Is my contract uploaded when I sign it?
No. The PDF and your signature are processed entirely in your browser — neither ever reaches a server. That matters for exactly the kind of documents people sign.
Is this a legally binding signature?
It places an image of your handwritten signature — a “simple electronic signature”, widely accepted for everyday agreements, forms and letters. It is not a cryptographic (qualified) digital signature; for flows that legally require certificate-based signing, use a qualified provider.
Can I sign in more than one place?
Yes. Click every spot that needs a signature — initials on each page, full signature at the end. Each placement can be moved and resized independently.
What makes a good signature photo?
Dark ink on white paper, photographed straight-on in good light. The tool removes the white background automatically and trims the edges.
