About Sign PDF
Sign PDF adds your name as a typed signature near the bottom of the first page, the last page or every page — a quick way to sign letters, forms and simple agreements.
How to use Sign PDF
- Add the PDF.
- Type your name as you want it to appear.
- Choose where to sign: last page only (usual for letters and contracts), first page or all pages (for initialling).
- Press Sign PDF and download.
Tips for better results
- Make all other changes — merging, page numbers — before signing.
- Check the signature doesn't cover existing text at the bottom of the page.
- If the other side asks for a certificate-based 'digital signature', use the service they specify instead.
Limitations
This adds a typed signature, not a certificate-based digital signature. In England and Wales an electronic signature is generally acceptable for many documents, but some — such as deeds that need witnessing or certain official forms — have extra requirements.
