Step-by-step
How to prepare and inspect the result
Prepare a raster file
Select PNG, JPG, or WebP up to 40 MB. SVG, PDF, and other document files are not supported by the image input.
Start with color removal
Use Solid-color fast with the subject away from the corners. Try Crisp edge if thin ink or small lettering is being removed.
Inspect the details
Check letter interiors, thin lines, white details, and paper shadows. Download a transparent PNG when the preview is suitable.
Before you export
Limitations and checks
- White logo elements on a white backdrop can vanish. Color removal cannot tell which matching pixels belong to the logo.
- Detailed edges is an alternative to try, but small text and geometric marks are not guaranteed to be preserved.
- The output remains a raster PNG. The tool does not create SVG paths, sticker outlines, print bleed, or a legally validated electronic signature.
FAQ
Frequently asked questions
Does this authenticate a signature?
No. It changes image transparency only. It does not verify identity, consent, authorship, or the legal status of a signature.
Can it upscale or redraw a small logo?
No. The export keeps the source dimensions and does not reconstruct detail or create vector artwork.
