How to process multiple signature scans into a ZIP
Inspect the source before masking
Open a set of approved signature scans and crop out unrelated text while keeping a quiet margin around the ink.
Repair different lighting across files one area at a time
Compare the preview on a dark canvas, then brush away one-off marks on each page.
Export a folder of forms-ready signatures
Choose PNG transparency, download the result, and keep the original beside it for review.
Choose the right source for this workflow
For a set of approved signature scans, use even light and a flat page. Leave a little canvas around each stroke so the mask can follow its contour.
Avoid screenshots and repeated re-exports; they exaggerate different lighting across files and make fine ink harder to separate.
Tune the mask for different lighting across files
Preview against two contrasting colors to find one-off marks on each page. Make small changes and compare with the source after every pass.
If a stroke becomes pale, lower the tolerance and use Restore on that short segment rather than rerunning an aggressive removal.
Save a reusable asset set for related forms
Download transparent PNGs and label them with the signer, date, and intended use in a folder of related forms. Keep the source scans in a private folder.
The result is a visual image layer, so use formal signing or identity checks whenever the workflow requires them.
Different lighting across files: signature cleanup questions
Can this page handle a set of approved signature scans?
Yes. It accepts a set of approved signature scans and processes it in the current browser tab. A flat, sharp source gives the cleanest mask.
How do I remove different lighting across files?
Start with a conservative tolerance, inspect the edge at 100%, and use Erase only on one-off marks on each page.
What if the file includes marks beyond the signature?
Crop before processing, then use the brush for one-off marks on each page. The tool does not invent missing handwriting.
Where can I place the cleaned image?
A transparent PNG works well on a folder of related forms; check the signer and document authorization before sharing it.
Does batch or local processing change the original?
No. The original remains available in this tab and the exported copy is a separate file.
