How to Sign a PDF Online for Free (Draw or Upload Signature)

Need to sign a form or document? You can sign a PDF online for free right in your browser — no app to install, and your file is never uploaded to a server.

Two ways to add your signature

• Draw: use your mouse or finger to draw your signature on screen.
• Upload: upload a photo or transparent PNG of your existing signature.

Steps to sign a PDF

1. Open the Sign PDF tool and add your PDF.
2. Draw your signature or upload a signature image.
3. Click "Place on page", then drag it to the right spot and resize it.
4. Click "Save signed PDF" to download.

Is it safe?

Yes. The signing happens entirely in your browser, so your document stays on your device. Nothing is sent to a server in normal use.

Tip for a clean signature

If you upload, a transparent PNG looks best because the background will not cover the document. A black signature on a transparent background is ideal.
