A browser-based signature pad that uses the HTML5 Canvas API for smooth, pressure-sensitive-style drawing. All processing happens locally — no data is ever sent to a server. Export your signature as a fully transparent PNG ready for overlaying on documents.
No. The Canvas Signature Pad processes everything locally in your browser using the HTML5 Canvas API. No data is transmitted to any server. Your signature stays entirely on your device.
Yes. The pad supports touch events natively, making it ideal for tablets and smartphones. For best results, use a stylus on tablet devices for more natural handwriting.
Select "Transparent" in the Background dropdown (this is the default). When you click Download PNG, the exported file will have a fully transparent background, perfect for overlaying on documents.
Copying as Base64 puts a data URI string on your clipboard that you can embed directly in HTML, CSS, or email templates — no external file needed. It looks like data:image/png;base64,...
Yes. The Undo button removes your last stroke one at a time. This lets you correct mistakes while keeping the rest of your signature intact.
This tool produces an image of a handwritten signature. For legal enforceability, you should use it within a compliant e-signature workflow (with audit trails, timestamps, etc.) as required by your jurisdiction.
A canvas signature pad is a browser-based drawing tool that allows users to create a handwritten signature using a mouse, touch screen, or stylus. Unlike traditional wet-ink signatures, digital signature pads capture the motion and pressure of your hand to create a realistic-looking cursive or printed signature that can be saved as an image file and used across documents, websites, and digital workflows.
Our Canvas Signature Pad is built entirely on the HTML5 <canvas> element, which means it runs 100% in your browser with zero server interaction. It supports mouse events on desktops and touch events on mobile devices and tablets, making it universally usable on any modern device without installing any software or app.

Behind the scenes, the tool uses the Canvas 2D rendering context to capture pointer coordinates at each frame. When you press and drag, it draws lineTo() paths using the Bézier curve smoothing algorithm — this gives strokes a natural, flowing appearance rather than jagged pixel-by-pixel lines. The pen size slider controls lineWidth, and the color picker sets strokeStyle directly on the canvas context.
Each stroke is recorded as a separate path. The Undo function works by saving a snapshot of the canvas state after each stroke using canvas.toDataURL() and restoring the previous snapshot when triggered. This gives you granular undo control without clearing your entire signature.
The most common use case is exporting a signature with a transparent background. When you select "Transparent" as the background option, the canvas background color is not painted — only your strokes are rendered. The canvas.toBlob() API then encodes the canvas content (including transparency) into a PNG file, which you can download directly to your device.
PNG format is ideal for signatures because it supports full alpha transparency. This means you can place your exported signature image on top of a document, PDF background, or email template without any white or colored box surrounding it. The signature integrates seamlessly with whatever is behind it.
The Base64 export option converts your canvas image into a data URI string. A data URI embeds the raw image bytes directly in a text string, starting with data:image/png;base64, followed by the Base64-encoded image data. You can paste this directly into an HTML <img> tag's src attribute, a CSS background-image property, or the body of an HTML email — eliminating the need to host the image file separately.
This is particularly useful for developers embedding a personal or placeholder signature in a static HTML document, for automated document generation scripts that need an inline image without file system access, or for including signatures in HTML email templates.
The pad listens to both mousemove and touchmove events, making it equally functional on desktop browsers and on touchscreen devices. When used with a passive stylus on iPad or Android tablets, the result closely approximates a natural handwritten signature. For the most authentic result on touchscreens, use slow, deliberate strokes and a stylus if available.
We also call event.preventDefault() on touch events inside the canvas to prevent the page from scrolling while you draw, ensuring a smooth, uninterrupted drawing experience on mobile.
Document signing: Generate a signature image to place on PDFs, contracts, or invoices created in Word or Google Docs. Export as PNG and insert as an image on the signature line.
Email signatures: Create a handwritten-look signature to embed in your HTML email template using the Base64 output. This adds a personal, authentic touch to business correspondence.
Web forms: Developers can integrate the signature pad concept directly into web applications by embedding similar canvas logic for end-user e-signature capture in checkout flows, consent forms, and legal agreements.
Branding: Artists and designers use signature pads to create a genuine handwritten logo or artist signature for watermarking digital artwork. Export with transparent background and overlay on your work.
Because this tool runs entirely in the browser with no server-side processing, your signature data never leaves your device. There is no account, no login, and no data retention. The canvas content is only accessible within the current browser session and is discarded when you close the page or refresh it. This makes the Canvas Signature Pad appropriate even for sensitive use cases where privacy is a concern.
