How to Sign PDF Online with Format PDF

Printing a document just to sign it and then scanning it back in belongs in the past. Format PDF lets you sign directly inside the PDF, right in your browser, whether it's a single contract or a stack of files that all need your signature before the end of the day.

Draw your signature once, place it wherever it's needed, and download the finished document. No printer, no scanner, no extra software sitting on your computer.

Why Sign PDFs Online Instead of by Hand

Paper signing slows everything down. You need access to a printer, a scanner, and enough time to shuffle physical pages back and forth, and that's before you factor in mailing or emailing the scanned copy. An online signature skips all of that. You open the file, sign it on screen, and it's ready to send within a minute.

It also holds up better for records. A digitally signed PDF looks the same on every device, doesn't fade or get lost like a paper copy can, and is far easier to search through later if you need to find it again.

Step by Step: How to Sign PDFs

Upload the document. Add the PDF you need to sign from your device or drag it into the tool.
Create your signature. Draw it with your mouse or your finger on a touchscreen, or type your name and pick a signature style if you'd rather not draw one.
Place it on the page. Drag your signature to the exact spot it needs to go, and resize it if necessary. You can add it to as many pages as the document requires.
Download the signed file. Save the completed PDF to your device, with no watermark added and nothing left behind on any server once you're done.

The process works the same on a laptop, a tablet, or a phone, so a document that needs a signature doesn't have to wait until you're back at your desk.
