Type your signature, place it anywhere on the page and drag it into position. No printing, no scanning.
Printing a contract, signing it, scanning it back and hoping the result is legible is a ritual nobody enjoys. Sign the document where it already is. Type your name, choose a size and color, and place the signature anywhere on any page -- then drag it until it sits exactly on the line. The mark is written into the PDF as real content, so it survives being emailed onward, printed, or opened in a different reader. You can add a date, initials or a job title the same way, and every mark stays listed in a side panel so you can move or remove it before you download.

What people usually want to know before they upload a document.
That depends on your jurisdiction and on what the parties agreed, not on the tool. In many places a typed or drawn signature is accepted for ordinary commercial documents, while deeds, property transfers and some regulated filings need a qualified digital certificate. This tool adds a visible signature, not a cryptographic certificate -- if you need the latter, use a certificate-based service.
The web tool types the signature in a script face. If you want your own handwriting, sign a blank sheet, photograph it, and place it with the image tools before downloading.
No. It is placed at fixed coordinates on the page, exactly like the rest of the document's content, so it renders identically in every reader.
