Sign a PDF online

Signing a PDF online means you can return a signed contract, form or letter without printing, signing by hand and scanning it back — the whole round trip collapses into a few clicks in your browser. Open your document, create a signature by drawing it with a mouse or finger, typing your name in a handwriting style, or uploading an image of your real signature, then drag it to the exact spot on the page and size it to fit. You can place it on any page and add a date or initials alongside. When you download, the signature is part of the finished PDF, ready to email back. Doing this online is convenient on a managed or borrowed computer where you cannot install software. Crucially, this tool runs entirely in your browser, so a sensitive agreement is never uploaded to a server — your document and your signature stay on your device, which matters a great deal for anything legal or financial.
