Open a PNG, JPG, or WebP with a solid background
Choose a PNG, JPG, or WebP image. Look for a mostly uniform background that differs from the subject. The sample is a useful way to learn the controls before editing your own file.

How to use the chroma key remover online
02
Choose a custom chroma key color and refine the edge
Use the eyedropper on a representative patch of backdrop. Raise tolerance until the screen disappears, add a little softness, and use spill reduction if green or blue reflections remain.
03
Download your image as a transparent PNG
Compare the original and result around hair, logos, and small props. Keep the background transparent for a PNG cutout, or choose a color or image for a finished composition.
Remove green, blue, or a custom background color from an image
Chroma keying builds transparency from color differences. This is useful for portraits filmed against a screen, a product photographed on a flat backdrop, or a graphic with a distinct background color. The tool supports green, blue, and custom colors; it does not need a particular shade of green.
The selected color matters. A sample from a shadow or bright hotspot can be less representative than the main screen color. If the subject contains the same hue, a broad tolerance may remove that detail too. Start conservatively and use the comparison preview while adjusting.
Refine chroma key edges before saving a transparent PNG
Tolerance expands the range of colors removed. Softness changes the transition at the edge, while spill reduction reduces excess green or blue near the keyed hue. Adjust one control at a time so you can see which problem it solves.
Inspect the cutout over both light and dark backgrounds. A detailed replacement scene can hide a leftover fringe that becomes obvious when the PNG is used elsewhere. If the source has strong shadows, heavy compression, or matching subject colors, improving the photo can help more than increasing every slider.
What to know before using this chroma key remover
- This tool removes a color, not a person or object using AI segmentation.
- A busy backdrop or a subject matching the key color may not separate cleanly.
- Animated images are treated as a still image; animation is not preserved.
PRACTICAL ANSWERS
Chroma key remover questions and answers
Formats, useful settings, and the details that affect your result.
Can this image chroma key remover remove a custom background color?+
Yes. Choose a custom key color or sample it with the eyedropper. The background should be mostly uniform and distinct from the foreground.
Why does increasing tolerance remove parts of my subject?+
Those pixels are close to the chosen key color. Lower tolerance, choose a more representative backdrop sample, and check whether your subject shares the background's hue.
What is the difference between softness and spill reduction?+
Softness smooths the transition in transparency. Spill reduction changes excess green or blue near the keyed edge. One blends the outline; the other reduces a color cast.
Does converting JPG to PNG create a transparent background?+
Changing the format alone does not remove a background. Apply the key, choose a transparent background, and export PNG to keep the newly transparent pixels.
Can I download the chroma key result as a transparent PNG?+
Yes. After removing the selected background color, choose a transparent background and PNG output. The checkerboard only previews transparent pixels and is not drawn into the downloaded image.
Is my source photo uploaded for chroma key processing?+
No. The editor reads and processes your selected photo in the browser. Hosting still receives ordinary requests for the website and its assets.
