How to use Extract Color From PNG

What the tool does, how to run it, and what to expect from the result.

How to isolate one color in a PNG

To isolate a color, load one PNG, click the target color to sample it, then adjust tolerance and edge softness until the selection looks right. The Extract Color From PNG tool keeps that color range and makes everything else transparent, then exports the result as a PNG.

Tolerance controls how wide the sampled range is, so you can capture slight shade variations, while edge softness smooths the boundary for cleaner masks. An invert mode flips the behavior so the sampled range is removed and the rest of the image stays.

  • Click to sample the target color
  • Adjust tolerance for the color range
  • Set edge softness for clean edges
  • Use invert mode to flip the selection
  • Export a transparent PNG

Extracting a color vs. making one transparent

Making a color transparent removes the chosen range and keeps the rest. Extract Color From PNG does the opposite by default: it keeps the sampled color range and clears everything else, which is often better for building masks and prepping simple assets.

This works best on flat graphics, logos, simple icons, and other images where the target color is visually distinct. On photos with gradients or noise, results will be looser, but tolerance and edge softness give you room to tune the selection. The invert option covers the reverse case when you do want the color removed.

  • Keeps the sampled color by default
  • Invert to remove it instead
  • Best for flat graphics, logos, and icons
  • Tune with tolerance and edge softness
Tips

Getting a better result out of Extract Color From PNG

Specific settings and thresholds, not general advice.

  • This is the inverse of making a color transparent. Here, the matched color is what you keep and everything else is deleted, so the output is a PNG containing only the pixels that were within tolerance of the one you picked.
  • You pick the color by clicking directly on the image, which samples that exact pixel rather than making you guess a hex value. Zoom in mentally: the pixel you land on in a soft-edged area might be a blend rather than the fill color you meant.
  • Tolerance runs from 0 to 255 and defaults to 36. It is a straight-line distance in RGB space, where the largest possible distance between any two colors is about 441. So 36 is a fairly tight neighbourhood, and something like 120 will pull in a substantial slice of the color cube.
  • Edge softness, defaulting to 24, creates a feathered band beyond the tolerance where pixels fade out rather than being cut. It is what stops the isolated region from having a jagged, aliased boundary.
  • The invert switch flips the whole operation into a delete: the matched color becomes transparent and everything else survives. That makes this one tool for both isolating a color and removing one, which is worth knowing before opening a second tab.
Limits

What Extract Color From PNG does not do

The honest boundary, so you do not lose time finding it yourself.

  • PNG input only.
  • It matches by color similarity, not by region. Pixels of that color anywhere in the image are affected.
  • RGB distance is not perceptual, so a single tolerance value behaves differently in dark and light areas of the same image.
  • It cannot isolate a shape or an object, only a color.

Photos & videoColor gamutColor gamut is the range of colors a device, format, or color space can capture, store, or display. A wider gamut covers more saturated and vivid colors; a narrower one clips them to its nearest available shades.GeneralEditing & toolsTransparent backgroundA transparent background means part of an image has no color at all, so whatever sits behind it shows through. It relies on an alpha channel and must be saved as a format that supports transparency — usually PNG or WebP — since JPEG cannot store it.General

Ideal for

Isolating one color in a PNG while keeping the workflow transparent and export-ready

FAQ

Common questions

Short answers for the questions people usually have before trying a utility like this.

Can I invert the selection?

Yes. Invert mode flips the behavior so the sampled color range is removed and the rest of the PNG stays visible.

What PNG files does this work best on?

It works best on flat graphics, logos, simple icons, and assets where the target color range is visually distinct.

Does the export stay a PNG?

Yes. The result is exported as a transparent PNG directly in your browser.

Does this tool upload my image?

No. Extract Color From PNG runs entirely in your browser, so your image is never uploaded.

Is Extract Color From PNG free?

Yes. It is free to use, private, and fully client-side with no sign-up required.

What is this actually useful for?

Pulling one element out of a flat graphic. Isolating a single data series from a chart, lifting one color of a multi-color logo so it can be recolored, extracting the ink from a scan of line art, or making a mask from a color-coded diagram. It works because those images have deliberate, flat, distinct colors.

Why is nothing extracted when I click on my subject?

Almost certainly because the tolerance is too low for the image. Photographs, gradients, and lossy sources spread a nominal single color across hundreds of nearby values, so a tolerance of 36 catches only a small fraction. Raise it and watch the preview, but be aware that at high tolerance you start pulling in colors that just happen to be nearby in RGB space.

How does this differ from making a color transparent?

It is the same test with the opposite outcome. Make Color Transparent deletes the matched pixels and keeps the rest. This keeps the matched pixels and deletes the rest. The invert switch here gives you the first behaviour too, so you can flip between isolating and removing without changing tools.

What does edge softness do to the result?

It creates a band just beyond your tolerance where alpha ramps down gradually instead of dropping to zero. Without it, an antialiased edge is chopped at a hard threshold and the isolated region ends up with a jagged, stair-stepped outline. With it, the boundary fades and composites cleanly onto another background.
