Pick a pen color and a stroke width, draw your signature, and download it as a transparent PNG you can drop into a PDF, an email, or a document. The signature is drawn in your browser. The PNG is generated locally. Nothing is sent to a server — for sensitive documents, this is the safe option. ## How to use 1. **Pick a pen color and width** — Black, blue, and brown are the standard picks. Width 2-4 reads like a real pen on screen. 2. **Draw your signature** — Mouse, trackpad, or touch. Use the stroke for a natural rhythm — small movements produce smoother curves. 3. **Download the PNG** — Transparent background, ready to drop into a document or an email signature. ## Examples ### Email signature Make a handwritten-style signature for the bottom of your emails. Combine with the Email Signature Generator for a complete signature block. Input: ``` Draw your signature, pick a blue pen ``` Output: ``` A transparent PNG you can paste at the bottom of your email. ``` ### PDF signing Most PDF editors let you drop a PNG signature onto a signature line. Generate the signature here, place it on the line. Input: ``` A simple signature in black ``` Output: ``` A clean PNG signature, drop into the PDF editor on the signature line. ``` ### Document header or business card Drop the signature PNG into a design tool as a transparent overlay. It will sit on any background color or image. Input: ``` A wide signature in dark brown ``` Output: ``` A transparent PNG that overlays cleanly on any background. ``` ## FAQ ### Is my signature uploaded? No. The signature is drawn into a local HTML5 canvas, exported to a PNG data URL, and downloaded. Nothing is sent to a server. For sensitive documents, this is the safe option. ### What is the canvas size? The default is 800×300 pixels, which gives plenty of room for a flowing signature. The PNG export is the same size. For a tiny signature, use a smaller canvas; for a long signature with flourishes, the default is fine. ### Is the PNG background transparent? Yes. The export uses a transparent background so the signature drops onto any color or image without a white box around it. ### Can I sign on a phone or tablet? Yes. The tool listens for touch events as well as mouse events, so you can sign with a finger or a stylus on a touch device. ### Does it smooth my lines? Yes. The tool uses a quadratic-curve smoothing technique that connects the points you draw with smooth Bézier curves, so a slightly shaky line comes out looking natural rather than jagged. ## Related tools - [Meme Generator](https://uttir.com/meme-generator) — Add classic top-and-bottom text to any image, then download the meme as a PNG.
