Online Signature Maker
Create a clean digital signature in seconds, free and entirely in your browser.
What is it?
Online Signature Maker is a free, browser-based tool that lets you draw a smooth, natural-looking signature using your mouse, trackpad, or finger on a touchscreen. The drawing engine uses bezier curves to smooth out the strokes as you write, so the result looks handwritten rather than jagged. Once you are done, you can download your signature as a transparent PNG for overlaying on documents or as a white-background PNG for simpler use cases.
How to use it
- Select your pen color and stroke width using the controls above the canvas.
- Draw your signature on the canvas with your mouse, trackpad, or finger.
- If you make a mistake, use "Undo" to remove the last stroke or "Clear" to start over.
- Choose your preferred download format: "Download PNG" for a white background or "Download Transparent PNG" for a clear background.
- Save the file and insert it into any document, PDF, email, or form that needs your signature.
Why use this tool
Whether you need to sign a PDF, add a personal touch to an email, or prepare a signature image for a document template, this tool handles it in seconds without any app to install or account to create. Because everything happens entirely in your browser, your signature is never sent to any server, so your handwriting stays completely private. The transparent PNG option makes it easy to drop your signature onto any background color without an ugly white box around it. Note that signatures created here are image-based and are not legally binding electronic signatures under laws such as eIDAS or ESIGN unless paired with an appropriate verification process.
Frequently asked questions
Is my signature sent to a server?
No. The entire drawing process and export happen in your browser using the Canvas API. Nothing is ever uploaded or stored anywhere.
What is the difference between the two download options?
"Download PNG" gives you a signature on a white background, which is ideal for printing. "Download Transparent PNG" removes the background entirely, so you can overlay it on any colored document without a white box.
Can I use this signature on PDFs and official documents?
You can insert the image into a PDF using a PDF editor, but this is an image signature, not a legally binding electronic signature. For documents that require legal validity, use a dedicated e-signature platform.
What devices does it work on?
It works on desktop and laptop computers with a mouse or trackpad, and on smartphones and tablets using your finger or a stylus.
Can I adjust the thickness and color of my pen?
Yes. Before drawing, you can set the pen color to any hex color and choose a stroke width that matches the look you want.
