Runs in your browser · No sign-up

This adds a picture of your signature (a visual electronic signature). It is not a certificate-based digital signature: it does not prove who signed or detect later changes. Check whether a visual signature is accepted for your document.

How to use

  1. Choose a PDF, then draw your signature, type your name in a handwriting style, or upload a photo of it.
  2. New signatures appear on the current page automatically. Drag to move and drag a corner to resize; click a saved signature to add another copy.
  3. Select Apply signatures and download the signed PDF.

Example

Open page 3, create a signature and drag it onto the signature line, then add today’s date beside it → both appear on page 3 of the downloaded PDF.

Details and limitations

The signature is embedded as a transparent PNG image at the exact spot you chose, including on rotated or cropped pages. The rest of the PDF is not changed.

Choose handwriting or regular fonts for the page language. The selected font is downloaded from Google Fonts; your name stays on your device. If loading fails, a notice explains the system-font fallback. Characters absent from a font use a local fallback.

FAQ

Is this a legally binding digital signature?

It is a visual electronic signature image, not a certificate-based digital signature. Many everyday forms accept it, but documents that require a qualified or certificate-based signature need a dedicated signing service.

Can I sign a PDF on my phone?

Yes. Draw with your finger on the signature pad, then tap the page to place it and drag the corner handle to resize.

Are my PDF and signature uploaded?

No. Everything runs in your browser and nothing is stored after you close the page.
