What makes a signature scan hard to cut out
Paper is never one white
A scan of white paper is not a single value. Shadow near the fold, warmth from the scanner lamp, and JPEG compression spread it across dozens of near-identical greys. That is why the tolerance here starts at 35 rather than the 20 a clean graphic needs.
Tolerance decides how much paper goes
Matching runs in Lab colour space, which measures difference the way the eye does. Raise tolerance until the last grey around the strokes disappears. Push it too far and the thin ends of the pen strokes start dissolving, because faint ink is closer to paper than it looks.
It has to be a PNG
Transparency lives in the alpha channel and JPG does not have one. A transparent signature saved as JPG comes back with a solid white box around it, which is exactly the thing you were trying to remove.
Nothing is uploaded
A signature is a legally meaningful mark, and this one never leaves your machine. The transform runs on a canvas in your own browser, so no copy of your signature is sent to a server to be processed.
Photograph or scanner
A flatbed scan at 300 dpi or more gives the cleanest result because the lighting is even. A phone photo works, but shoot it in flat daylight rather than under a lamp, since a bright hotspot on one side of the page makes a single tolerance value fit one half of the image and not the other.
How to transparent signature maker
Upload the signature
Drop in a scan or a photo. Sign in dark ink on plain white paper for the cleanest cut-out. Scanned to PDF instead? A single-page PDF works as well — page 1 is turned into an image in your browser.
Knock out the paper
The paper colour defaults to white. Raise the tolerance slider until the background is fully transparent and only the ink remains.

Where a transparent signature is needed
Contracts and agreements
Drop your signature straight onto a PDF or Word document without printing and rescanning.
Email signatures
Add a real signature to a mail footer where a white box would look pasted on.
Letterhead and invoices
Sign templates once and reuse the file across every document you send.
Certificates
Place an authorising signature over a designed background without hiding the design.
Or just ask
Describe the edit in your own words
Type what you want changed and the assistant does it on the canvas — each step lands as a layer you can reopen, so nothing it does is baked in.
