Practical guide
Swap one image color for another with a tolerance you control
This tool compares every pixel with the source color you pick and rewrites the pixels whose red, green and blue distance falls inside the tolerance you set. A small tolerance changes only near-exact matches, while a larger tolerance also catches compression noise and soft edges around the target area.
Steps
- Choose one JPEG, PNG or WebP image up to 8 megapixels.
- Set the source color to the exact value you want to remove.
- Set the replacement color and adjust the RGB tolerance.
- Compare the original and result, then download the PNG.
Settings and output
- Source color
- The color the tool searches for; read it from the image first if you are unsure.
- Replacement color
- The color written into every matched pixel, with the original alpha preserved.
- Low tolerance (0–20)
- Changes only near-exact matches; good for flat logos and screenshots.
- High tolerance (60+)
- Also catches shading and JPEG noise, but can spill into similar nearby colors.
