Printing a document, signing it by hand, and scanning it again wastes time. A signature placed directly onto the PDF does the same job in under a minute.
The Sign PDF tool lets you draw your signature, type it, or stamp an image of it onto any page and position it exactly where it belongs. Your signature is added in your browser and is not sent to anyone.
How it works
There are different kinds of signatures. The one this tool adds is a visual or electronic signature: a picture of your signature placed on the page. A certificate-based digital signature, by contrast, is cryptographically tied to your identity. Many everyday agreements, forms and approvals accept a visual signature, but some authorities or contracts require a certified one, so always check what the recipient expects.
When this is useful
- Returning a signed contract, lease or quotation by email.
- Signing a consent form or application without a printer.
- Adding an approval to an internal document.
- Signing delivery notes or timesheets on a tablet.
- Initialling pages of an agreement.
Step-by-step instructions
- Open the Sign PDF tool and choose your PDF.
- Create your signature by drawing, typing or uploading an image.
- Click on the page where it should appear, then resize and move it.
- Save the signed PDF, and keep a copy for your records.
Tips for the best results
- Draw on a touch screen for a natural look.
- Use a high-contrast signature on a transparent or white background.
- Sign only the final version, because later edits can invalidate trust in the document.
- Protect the signed file with a password if it contains private information.
Common problems and how to fix them
The signature looks pixelated
Draw it larger and scale it down, or use a higher-quality image.
The recipient wants a certified signature
Some organisations require a certificate-based digital signature from an accredited provider. This tool adds a visual signature only.
