- 1. Sign on plain white paper with dark ink (black or dark blue works best).
- 2. Photograph it straight-on in even daylight, or scan it at 300 DPI or more.
- 3. Drop the image above — the AI erases the paper and keeps only the ink strokes.
- 4. Download the transparent PNG and insert it into Word, Google Docs, a PDF form or your email signature.
Why a transparent signature PNG?
- No white box around your signature on documents and PDFs.
- Looks genuinely “signed” instead of pasted on.
- Works over letterheads, colored backgrounds and forms.
- Reusable forever — sign once, use on every document.
Tips for a clean cutout
- Use plain, unlined white paper — no texture or printed logos.
- Avoid shadows across the signature; light from the side.
- Crop tight around the signature before processing.
- A felt-tip or fountain pen gives thicker, cleaner strokes than a pencil.
Where to use your transparent signature
Digital contracts and agreements, PDF forms, invoices and quotes, email signature blocks, cover letters, and internal approvals. Need to resize the PNG for a specific form? Use the image resizer, or compress it before emailing. For product photos instead, try the white background maker.
FAQ
How do I remove the background from my signature?
Photograph or scan your signature on plain white paper, drop the image into the tool, and the AI erases the paper background. You download a transparent PNG ready to place on any document.
Does the transparent PNG work in Word and PDF documents?
Yes. Transparent PNGs drop cleanly onto Word, Google Docs, PDF forms and email signatures without the white box you get from a JPG.
Is my signature uploaded to a server?
No. The AI cutout runs entirely in your browser, so your handwritten signature never leaves your device — important for a biometric identifier.
How do I get the cleanest result?
Use dark ink on plain white paper, photograph it straight-on with even light and no shadows, and crop close to the signature before processing.
Can I make the signature transparent but keep the ink black?
Yes — the AI removes only the paper background. The ink strokes keep their original color, so black or blue ink stays exactly as written.
