How It Works

Removing background from a signature is for a PNG overlay. It is not a legally certified e-sign product — use your own signing process for binding documents.

  1. Upload your image. Drag and drop a JPG, PNG, or WebP file up to 10 MB, or click the upload zone to browse. Your original preview appears immediately on the right.
  2. Remove the signature background. Click Make background transparent to run AI cutout in your browser. A loading indicator shows model download and processing progress on the first visit.
  3. Refine and download. Use the before/after slider to inspect edges, then crop to the subject, add padding, a drop shadow, or a sticker outline. Download a transparent PNG or WebP.

Jump back to the remove background from signature tool anytime to process another file.
