The fastest way to sign a PDF online
Signing a PDF online used to mean creating an account, hitting a paywall after one free file, or uploading your private contract to someone else’s server. PDFArena removes all of that. Open the page, choose your PDF, and you are already signing — no email, no credit card, no “free trial” that expires.
Because everything runs locally in your browser using JavaScript, your file is read straight off your device and never transmitted anywhere. That makes it ideal for signing sensitive documents like contracts, NDAs, offer letters, and tax forms where uploading to a third party is a real privacy concern.
Works on every device and browser
PDFArena works in Chrome, Safari, Firefox, and Edge on Windows, macOS, Linux, ChromeOS, iPhone, iPad, and Android. On a touchscreen you can draw your signature with your finger; on a laptop use your trackpad or mouse, or just type your name in a signature font.

No learning curve, no account setup — done in under a minute.
Add your signature
Draw it with a mouse or finger, type your name, or upload a signature image. Drag it into position on the page.
