About this tool
Sign a contract, a form, or a permission slip without printing it or handing the document to a signing service. Draw your signature with a mouse, finger, or pen, or type your name in a script font, then click where it belongs on the page. Drag it into position, adjust the size, add it to as many pages as you need, and download the signed PDF.
The signature is embedded as an image in the document itself, exactly like a scanned signature, which is what most organisations accept for everyday paperwork. Unlike e-signature platforms, nothing is uploaded, no account is created, and there is no per-document fee.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your PDF file into the box above, or click to browse. Nothing is uploaded.
- Click the button and wait a moment.
- Download the result.
Frequently asked questions
Is this a legally binding electronic signature?
It is an image of your signature placed in the PDF, the digital equivalent of signing a printout and scanning it, which is accepted for most everyday agreements. It is not a cryptographic digital signature with a certificate; use a certified service if a counterpart requires one.
Can I add the date or other text?
Type the date as a typed signature using the Plain font and place it next to your signature.
Can I sign on my phone?
Yes. Drawing with a finger works, and the page preview scales to the screen.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
