How to use the signature pad
- Draw your signature in the white box â mouse on desktop, finger or stylus on touch screens.
- Adjust the ink color (classic blue or black) and pen thickness to taste.
- Made a wobble? Undo removes the last stroke; Clear starts over.
- Download as a transparent PNG â it layers cleanly onto any document â or with a white background.
Using your signature image
A transparent signature PNG is the most reusable format: insert it into Word or Google Docs above a signature line, stamp it onto a PDF with an editor's image tool, add it to your email signature, or keep it for invoices and quotes. Because the background is transparent, it sits naturally on top of lines and text instead of covering them with a white box. Sign larger than feels natural â a big, smooth signature scales down crisply, while a tiny one gets jagged when enlarged.
Benefits
- Draw with mouse, finger or stylus â smooth, pressure-free curves that look natural.
- Downloads as a transparent PNG that layers cleanly onto documents, or with a white background.
- Undo individual strokes instead of starting over.
- Completely private â the signature is drawn and saved locally, never uploaded.
Limitations to know
- It produces a signature image, not a certified e-signature â it carries no cryptographic identity verification.
- Nothing is stored between visits, so download your signature before leaving the page.
- Mouse-drawn signatures can look shakier than touch or stylus input.
Common mistakes to avoid
- Signing tiny â draw large and scale down for a crisp result.
- Downloading the white-background version and getting a visible box over document lines.
- Treating an image signature as sufficient for documents that legally require a verified e-signing service.
Alternatives
To place the signature into a document image, use Add Text to Image; to turn a signed page into a PDF, use Images to PDF.

Frequently asked questions
Is my signature uploaded or stored?
No â the pad is a canvas running entirely in your browser. Your signature never leaves your device, and nothing is saved after you close the page.
Is a drawn signature legally binding?
In many countries electronic signatures are legally recognized, but the rules depend on the document type and jurisdiction, and formal e-signing services add verification this simple image doesn't. For contracts of consequence, check what your jurisdiction requires.
Why download the transparent version?
It blends onto any background â signature lines, colored paper, PDFs â without a white rectangle around it.
Can I use it on my phone?
Yes â it supports touch and stylus input, and signing with a finger on a phone often looks more natural than a mouse.
