How to sign a PDF online
- Choose the PDF. The last page opens in the preview (signature pages are usually at the end).
- Draw your signature with your finger or mouse — or type your name, or upload a photo of your signature on white paper.
- Tap where it should go and adjust the size.
- Press Sign & download.
Legal note: in the US, the ESIGN Act and UETA generally treat electronic signatures like handwritten ones for most everyday agreements, and the UK and EU have similar rules. Some documents (for example wills or notarized papers) have special requirements — check if unsure. This is not legal advice.
Sign a PDF FAQs
Is this a “certified” digital signature?
No. It places an image of your signature on the page, which is what most forms ask for. Cryptographic certificate signatures need special software.
Are my PDF files uploaded anywhere?
No. The tool runs entirely in your browser using open-source libraries (pdf-lib and PDF.js). Your file is never sent to a server, so it is safe for contracts, bank statements and IDs.
Can I sign more than one page?
Yes. Sign one page, download, then load the signed file and sign the next page.
