Why would you need an e-signature on a PDF?
Printing a document just to sign it and then scan it back in wastes time and often produces a lower-quality result. An e-signature tool lets you sign directly on the digital file — by drawing your signature or uploading an image of it — and get a clean, ready-to-send document in seconds.
How the e-signature is added to the file
Your signature, whether drawn by hand or uploaded as an image, gets placed as an element directly on the page you choose, at the exact position and size you want. Once you download the file, the signature becomes a permanent part of that page, just like it would be with a physical signature on paper.

Practical tips before you start
Before signing your document, keep these points in mind:
- Draw your signature slowly for a cleaner, more legible result before placing it.
- Resize and reposition your signature carefully so it lands exactly where it's expected on the page.
- For documents needing a signature in multiple places, add it separately to each spot.
- Check your local legal requirements if the document is an official or sensitive one.
Electronic signatures are recognized in many countries and transactions, but requirements vary — check with the receiving party for sensitive official documents.
