How to use it

- Adjust edge softness for smooth strokes, choose ink colour and enable auto-crop.
- Click “Make transparent” and download the PNG — it works on top of any PDF or document.
Frequently asked questions
How do I take a good photo of my signature?
Black or blue pen on plain white paper, phone straight above, no shadow across the paper. The tool then removes the paper automatically.
Can I use this on official documents?
That depends on the document. Many organisations accept an image signature; some require wet ink. Check the recipient’s rules — the tool makes the image, not the legal decision.
Will the signature stay sharp?
The PNG is generated at the full resolution of your photo, so it stays sharp when scaled down. Auto-crop removes empty margins so it aligns nicely in documents.
Why is my result patchy?
Uneven lighting creates grey areas. Re-take the photo with even light, or lower the threshold and increase softness to bring strokes back.
Is my signature uploaded?
No — and this matters for signatures. The image is processed entirely in your browser.
