Sign in seconds
Draw your signature and drop it onto the page — no printing or scanning.
Place and resize
Position the signature precisely and size it to fit the signature line.
Private by design
Your document is signed on your device and never uploaded.
Sign a contract without printing
Skip the print-sign-scan loop on a PDF agreement or NDA. Draw your signature with a mouse, trackpad, or touchscreen, then click the exact spot on the page to drop it. Drag it onto the signature line and resize with the corner handle until it lines up. Download a finished, signed PDF in minutes without owning a printer or scanner.
Initial and sign every page
Some agreements, leases, and consent forms require your mark on every single page, not just the last one. Draw your signature once and click to place it on page after page throughout the document. The counter tracks how many you have added, and each placement can be repositioned individually, so a 20-page contract gets initialed everywhere it needs without redrawing.
Sign on phone or tablet
A touchscreen gives you a far more natural signature than a mouse ever could. The pad accepts finger and stylus strokes directly, so you can scrawl your real signature on a phone or tablet, tap the page to place it, and drag it into position. The whole flow runs in your mobile browser, with the signed PDF downloading straight to your device.
