What does Sign PDF do?
Sign PDF is a free online tool that can stamp a text signature on the last page of a PDF. The PDF result from Sign PDF is a separate copy to inspect before you use it elsewhere. One possible use is internal drafts marked with a reviewer name.
The signature tool adds typed text near the bottom-right corner of the final PDF page. It offers a visible acknowledgment mark for a draft or internal file.
The default wording is Signed, which you can replace with the text you intend to show. This tool renders the pages and annotates the final page.
It does not create a certificate, timestamp authority record or cryptographic signature check trail. A name typed on a page can be copied like any other visible text.
It does not prove who entered it. Check whether the receiving party accepts this kind of mark.
Dates or titles must be part of the wording you enter. Keep a record of the review outside this file.
For visible sign-off text placed on an informational file, choose a copy whose source content suits that purpose. Keep a local source for another trial.

For Sign PDF, your browser uploads the source to our file-processing server. This is a server task, not local editing.
Files are due for deletion within 1 hour. Cleanup runs during normal service operation. Keep a local download for future use.
