Drop in a phone photo or scan of a signature and get back a crisp image with a pure white background — no gray paper texture, no shadows — ready to paste into a POA, form, or letterhead.
Runs entirely on your device — your signature is never uploaded anywhere.
A signature photographed off paper almost always carries a faint gray or cream background, plus shadows and scan noise. Pasted onto a Word document or a Power of Attorney, that shows up as a dirty rectangle around the signature instead of blending in. This tool reads the background tone per pixel and pushes anything that isn't ink to pure white, so the signature drops cleanly onto any document.
No account, no install — the whole pipeline runs in JavaScript inside this tab.
JPG, PNG, WEBP or BMP — drag it in or click to browse. Nothing is sent to a server; the file is decoded locally in your browser.
Paper texture, shadows and scan noise are pushed to pure white while the ink stroke is kept (and optionally darkened for a crisper look). Blank margins are trimmed automatically.
A clean PNG or JPEG lands in your downloads folder, ready to paste into your POA, form, or any document that needs your signature.
Dexin's POA Generator merges applicant and trademark details into a ready-to-sign Form TM-M — paste your cleaned-up signature straight in.
