Frequently asked questions
How do I get a transparent background from a photo of paper?
Upload the photo and adjust the ink threshold. The tool measures the brightness of every pixel and turns the paper transparent while keeping the dark ink, fading through partial transparency at the edges so the stroke stays smooth rather than jagged. Raise the threshold if parts of the stroke are missing; lower it if the paper or a shadow is coming through.
My form wants the signature at exactly 140 × 60 pixels.
Choose that box from the list. The signature is scaled to fit inside it and centred, so you get the required file dimensions with the handwriting still the right shape — resizing straight to those numbers would stretch it, which is what makes a signature look forged.
Is a signature made here legally valid?
It is an image of your signature, which is what upload forms are asking for. That is a different thing from a cryptographic digital signature, which binds a document to a verified identity — if a process requires that, it will say so and will tell you which certificate authority to use.
How do I photograph a signature so it comes out well?
Sign on plain white paper with a dark pen, then photograph it straight on in even daylight — not at an angle, and not under a single overhead lamp that casts a shadow across the page. Fill the frame with the signature. Almost every poor result comes from the photo rather than the tool.
Is my signature stored or uploaded?
No. Everything happens in your browser and nothing is kept once you leave the page — which matters more here than on most tools, given what a signature is.
