Signature Background Remover
Turn a phone photo of your signature on paper into a clean signature on a pure white (or transparent) background - the shape most forms actually accept.

Why a photographed signature gets refused
You sign on white paper, photograph it, and the portal rejects it. The reason is almost never the signature — it's the paper. A phone camera turns white paper grey or yellow, and adds a shadow down one side. This lifts the ink off the page and puts it back on a genuinely clean background, which is what the form is actually checking for.

Common questions
Parts of my signature vanished.
Push the slider to the right. It's deciding what counts as ink versus paper, and a light pen or a faded pencil stroke sits close to the line. If that isn't enough, re-photograph it in better, even light — near a window works well — with no shadow across the page.
Should I choose white or transparent?
White, for almost every form — portals expect a normal JPEG on a plain background and some reject PNGs outright. Transparent is for when you're placing the signature on top of a document, for instance in the Sign PDF tool.
Can I use this on a coloured or lined sheet?
It'll do its best, but lined paper is genuinely hard — the rules are ink too. Plain white paper takes thirty seconds to find and gives a far better result than any amount of processing afterwards.
