What this tool does
Sign PDF lets you place a drawn signature or an uploaded PNG/JPG signature image on a PDF without uploading the document to a processing server. Choose whether the signature belongs on one page, all pages, custom pages, or different positions on different pages, then download a signed copy. It is designed for ordinary visual signature workflows such as approvals, acknowledgements, freelance paperwork, and forms where a signature image is acceptable. It is not a certificate-based digital signature service and does not replace dedicated e-signature platforms for regulated, identity-verified, or audit-trail-dependent workflows. The PDF and signature stay in your browser for this tool, so you can prepare a quick signed copy without putting the document through a file-upload converter.
How to use it
- Upload the PDF you are authorized to sign and review the page where a visual signature should appear.
- Draw a signature in the tool or upload a PNG or JPG signature image. A transparent PNG often gives the cleanest result.
- Choose whether to place the signature on the current page, every page, or a custom page list. Use separate placements when different pages need the signature in different locations.
- Position the signature carefully so it does not cover important text, dates, or signature lines.
- Apply the signature placement and download the resulting PDF.
- Open the downloaded copy before you send it. Check page placement and make sure the signature is readable at normal zoom.
Common use cases
- Sign a contractor agreement or routine approval form at home
- Place an approval signature on an invoice PDF before returning it
- Add the same visual signature to selected pages of a review packet
- Place signatures in different locations across a multi-page document
- Prepare an everyday signed copy before encrypting it for email
FAQs
- Is this a legally binding e-signature?
- This stamps a visual signature image onto the PDF. It is not certificate-based e-sign (like DocuSign). For regulated workflows, use a dedicated e-sign service.
- Does my PDF get uploaded?
- No. Signing runs in your browser. Your file and signature stay on your device.
- What image formats work?
- PNG and JPG. Transparent PNGs work best for a clean signature look.
- Can I sign multiple pages?
- Yes. Apply to this page only, all pages with the same position, custom pages (e.g. 1, 3-5), or save separate placements so different pages can use different spots—then apply once.
- Does this create a certificate-based digital signature?
- No. It adds a visual signature image to the PDF. It does not provide identity verification, a certificate, signing workflow, or an audit trail.
- Can I use a transparent signature image?
- Yes. A transparent PNG is often best because the page background shows through around the handwritten mark. JPG is also supported.
- How should I share a signed sensitive PDF?
- Review the signed download first. If a password is appropriate, use Encrypt PDF and send the password through a separate channel rather than the same email.
