Digital signature
Sign your PDF with your name, the date and a verifiable digital seal.
How to sign a PDF online quickly and securely
Need to return a quote, a purchase order, or a signed statement without printing? One2PDF lets you sign a PDF online for free, without Adobe Acrobat. Import the file, enter your name, choose the stamp position, then download the signed document.
Signing a PDF does not have to mean a pen and a scanner. The preview shows the stamp (name, date, reason) before export, on the last page or on every page. It is a practical way to sign a PDF in the browser, place a visible digital signature, or approve a file remotely.
Security stays at the center of the flow: the original is not kept, the signed PDF is available for download, then deleted. No account is required for occasional use. Sign your PDF now, check the stamp, and come back to One2PDF whenever a document must carry your name without being reprinted. The whole process takes only a few seconds, with no extra software on your computer.
