Drop the file on this page, convert, and download. No sign-in. No email. Nothing is stored between visits.

Is this a legally binding e-sign?

It stamps a drawn signature image on the last page. That is what most people mean by “sign PDF online.” It is not certificate-based eIDAS or DocuSign.

Will the result look identical?

Image and page conversions keep the pixels you dropped. PDF compression redraws pages as JPEGs so size drops — pick a higher quality if you need sharper type.

What about large files?

Your device memory is the limit. Very large PDFs (hundreds of pages) may be slow. Nothing is queued on a server.
