How to use this tool
Choose a file, click the colour to remove and adjust tolerance. Images wider than 900 pixels are reduced; inspect any foreground regions that share the background colour.
Results and examples
Selecting white at tolerance zero removes exact RGB matches. Raising tolerance includes nearby colours, so compare cleaner edges against unintended foreground loss.
Worked example
Selecting white at tolerance zero removes exact RGB matches. Raising tolerance includes nearby colours, so compare cleaner edges against unintended foreground loss.
Limitations
- Matching pixels are removed across the image regardless of their location.
- Hair, semitransparent shadows and complex backgrounds are not finely segmented.

Frequently asked questions
What does zero tolerance remove?
Selecting white at tolerance zero removes exact RGB matches. Raising tolerance includes nearby colours, so compare cleaner edges against unintended foreground loss.
Why can white foreground details disappear too?
Matching pixels are removed across the image regardless of their location. Hair, semitransparent shadows and complex backgrounds are not finely segmented.
