How it works
Add PDF
Drop one PDF file into the box above. It is read locally — nothing is uploaded.
Place your mark
Pick the page, click the preview where the signature goes, then draw, type or upload your signature.
Download
Hit Place signature & Download and get your signed PDF. Repeat for more pages.
Tips
- Draw slowly. A slow, steady stroke looks far more natural — hit Clear and retry as many times as you like.
- Upload looks most real. A photo of your ink signature on white paper beats any font for authenticity.
- It is ink, not a seal. This places a visible signature image — like signing a printout — not a cryptographic digital signature. It does not prove identity or detect later edits.
- Position precisely. Click the preview to drop the marker exactly on the signature line before downloading.
Frequently asked questions
How do I sign a PDF online?
Add your PDF, choose the page, and click on the preview exactly where the signature should go. Then draw your signature with your mouse or finger, type your name in a script font, or upload a signature image — and hit Place signature & Download.
Is this a legally valid digital signature?
This tool places a visible signature image on the page — like signing a printed copy. It is not a cryptographic digital signature, so it does not prove who signed or detect later changes. For contracts that require certified e-signatures, use a qualified e-signature service.
Draw, type or upload — which looks best?
Drawing with a mouse or finger (or uploading a scan of your ink signature) looks most like a real signature. Typing uses an elegant script font and is fastest, but looks less personal.
Can I sign more than one page?
One placement per download. To sign several pages, choose the next page, click its position and download again — repeat for as many pages as you need.
Are my PDFs uploaded to a server?
No. Your PDF and your signature never leave your device — everything happens locally in your browser, which is why the tool also works offline once the page has loaded.
Can someone tell if the PDF was changed after signing?
No. A visible signature is just an image on the page — it is not tamper-evident. Anyone with a PDF editor could move or remove it. Treat it like ink on paper, not a security seal.
