About

About Signature Generator

Draw directly on the canvas with your mouse, trackpad, or finger - touch devices work out of the box. Pick an ink color from the palette, adjust pen width, and use Undo to remove the last stroke or Clear to start over.

When you are happy with the result, download the signature as a transparent-background PNG at 512, 1024, or 2048 pixels. Transparent backgrounds let you place the signature over documents, invoices, emails, or watermarks without a white box.

Everything happens locally in your browser - strokes are never uploaded or stored.

    Signature Generator FAQ

    Find answers to common questions about drawing and exporting handwritten signatures.

    Can I draw with my finger on a phone or tablet?

    Yes. The canvas supports touch and pointer input, so you can sign with your finger or a stylus on touch devices just like with a mouse.

    Why is the PNG background transparent?

    Transparent backgrounds make the signature easy to place over documents, PDFs, invoices, and emails. If you need a white background, paste the PNG into an editor and add one.

    Which export size should I choose?

    512px is enough for email and most documents. Use 1024px or 2048px for print or when you may need to scale the signature up later.

    Can I use the signature legally?

    The tool produces an image of your handwritten signature. Whether it counts as a legal signature depends on your jurisdiction and the document - many regions accept electronic signatures, but check local rules for binding agreements.

    Is my signature stored anywhere?

    No. Strokes exist only in your browser session and disappear when you leave the page. Nothing is uploaded or stored on a server.

    Can I redo a stroke I removed?

    Undo removes the most recent stroke. If you remove too much, there is no redo - draw the stroke again or start over with Clear.
