Scanned Signature Cleanup: legible ink with the scan noise quieted
Bring an older scan with gray paper, dust, or ruled lines into a focused workspace. Check tiny loops and pressure changes before asking the mask to remove more. Preview the cutout, make small edge edits, and export a legible ink with the scan noise quieted for archives, retyped letters, and legacy paperwork.

Scanned Signature Cleanup for archives, retyped letters, and legacy paperwork
This workflow is tuned for an older scan with gray paper, dust, or ruled lines. Check tiny loops and pressure changes before asking the mask to remove more. The first pass runs in your browser; model files may be cached locally, while the selected image stays on your device. Compare a light and dark preview before downloading, and use the result only when you have permission to handle the signature.
How to quiet shadows and dust in a scanned signature
1. Start with an older scan with gray paper, dust, or ruled lines
Choose a sharp image, keep the full mark in frame, and leave a little breathing room around the handwriting.
2. Check the ink against the paper
Compare the original with the result on contrasting backgrounds. Check tiny loops and pressure changes before asking the mask to remove more. Use the small erase and restore controls for the last pixels.
3. Export a legible ink with the scan noise quieted
Choose a transparent PNG, keep the proportions, and place a copy in the intended document.
Prepare an older scan with gray paper, dust, or ruled lines for this pass
Start with an older scan with gray paper, dust, or ruled lines. Keep the camera parallel to the page, use even light, and crop away stamps, ruled lines, fingers, and desk clutter before processing.
Check tiny loops and pressure changes before asking the mask to remove more. A clean source usually beats an aggressive setting, especially when repeated JPG saves or screenshots have added pale halos.
Check the edge: check tiny loops and pressure changes before asking the mask to remove more
Use the dark preview to find gray scan noise and the light preview to check fine loops before increasing cleanup strength.
Use a transparent PNG as a reference while you work in small passes. Erase only obvious background specks and Restore only the strokes you can confirm in the source image.
Save legible ink with the scan noise quieted for archives
Export a legible ink with the scan noise quieted in a transparent PNG. Keep the original beside the cleaned copy so you can revisit a difficult edge or resize the mark without starting from memory.
A transparent image is a visual asset, not a formal electronic signature. Keep authorization and document review with the file.
Scanned Signature Cleanup: practical questions
Is scanned signature cleanup free to use?
Yes. Scanned Signature Cleanup is free to use in a modern browser; there is no account, payment step, or watermark.
Does scanned signature cleanup upload my image?
The selected image is processed in the current browser session. Site or model assets may download, but your image is not sent to an image-processing server.
What source gives scanned signature cleanup the cleanest edge?
Use an older scan with gray paper, dust, or ruled lines with even light, a clear edge, and no nearby marks that could be mistaken for part of the signature.
Which file should I download for a document?
A legible ink with the scan noise quieted in a transparent PNG is the practical choice here. PNG and WebP preserve transparency; use JPG only when you deliberately need a solid background.
How do I fix a faint stroke or a leftover edge?
Preview once on a dark background and once on a light one. Lower the removal strength for pale ink, then use Restore for a clipped stroke or Erase for a paper fleck.
