eSign PDF
Sign a PDF by drawing, typing or uploading your signature and placing it on the page.
eSign PDF online, free and private
Signing a PDF used to mean printing the page, scrawling your name, scanning it back, and hoping the result didn't come out crooked. eSign PDF skips all of that: you create a signature once — by drawing it, typing your name in a handwriting-style font, or uploading a picture of your ink signature — and then drop it straight onto the contract, form, or approval that needs it.
Everything happens right here in your browser. The document is opened into memory, your signature is embedded and flattened into the page on your own device, and the signed file is handed back as a download. Your PDF is never uploaded to a server, so a private NDA, lease, or offer letter stays entirely on your computer.
How to esign pdf in your browser
- 1
Open your PDF
Click ‘Select PDF file’ or drop the document onto the page. It renders in the viewer so you can scroll to the exact page and spot where a signature belongs.
- 2
Create your signature
Choose how to make it: draw with your mouse or finger, type your name and pick a cursive font, or upload a transparent PNG of your existing signature. You can redo it until it looks right.
- 3
Place it on the page
Click the spot on the document where the signature should go. It drops in there, and you can reposition or resize it so it sits cleanly on the signature line.
- 4
Download the signed PDF
Press the download button. Your signature is embedded and flattened into the page in your browser, producing a finished PDF that opens the same way everywhere.
Why use PDFToolz for this
Your document never leaves your device
The PDF is read, signed, and saved locally with client-side JavaScript. Because nothing is transmitted, there's no server copy of your contract to cache or leak — which matters when the thing you're signing is confidential.
A clean, flattened signature
Your signature is embedded and flattened into the page with pdf-lib, so it becomes part of the document rather than a movable overlay. The rest of the file's text, fonts, and images are left untouched.
Three ways to sign
Draw a fresh signature, type your name in a handwriting font, or upload a PNG of your real ink signature. Whichever you pick, the result is placed exactly where you click on the page.
Free, instant, and offline-capable
There's no account, watermark, or usage cap. Signing runs on your own hardware in seconds, and once the page has loaded it keeps working even without an internet connection.
