Step 1: Make your signature
Use the Signature Maker to draw a signature, type it in a handwriting font, or upload a photo of your real signature. You get a transparent PNG that sits cleanly on any page.

Step 2: Place it on the PDF
- Open Sign PDF and add your document.
- Add your signature image and drag it to the signing line.
- Resize it, then download the signed PDF.
Is it legally valid?
This places a visual signature image on the page, like signing a printed document. It does not use cryptographic certificates, so it is not the same as a qualified digital signature. For informal forms and many everyday documents it is accepted, but for contracts always confirm what the other party requires.
Tips for a clean signature
- Sign with a dark pen on plain white paper if you are photographing it.
- Photograph in good light, straight on, to avoid shadows.
- Keep the final PDF small with Compress PDF before emailing.
Frequently asked questions
Can I sign a PDF on my phone?
Yes. The tools work in mobile browsers; you can draw your signature with your finger.
Is an image signature legally binding?
It depends on the document and country. Informal documents usually accept it, but contracts may require a certified e-signature.
Can I sign multiple pages?
Place one signature per pass, then run the result through the tool again for another page.
