Invert an image's colors with an adjustable blend intensity.
Upload an image to preview the inverted result.
Color inversion flips every pixel to its opposite on the color wheel -- white becomes black, red becomes cyan, and so on -- producing the classic "negative" look. This tool adds a blend intensity slider, so instead of only a full 100% inversion, you can dial in anything from a subtle color shift to the complete classic negative effect.

New Channel Value = Channel + (255 − Channel − Channel) × Intensity
At 100% intensity, this reduces to the classic full inversion (255 minus the original channel value) for each of red, green, and blue independently. At lower intensities, the result blends between the original color and its full inversion, giving a partial, more subtle color shift rather than an all-or-nothing effect.
Creating a quick "negative" style effect for a creative photo edit. Generating a dark-mode-friendly inverted version of a simple graphic or icon. Experimenting with partial color inversion for a stylized, less extreme visual effect than a full negative.
Take a single pixel with red 200, green 100, blue 50. At 100% intensity the formula gives 255 - 200 = 55 for red, 155 for green, and 205 for blue, a completely different color. At 50%, each channel moves halfway toward its inverse. For red, 200 + (255 - 200 - 200) x 0.5 = 200 + (-145 x 0.5) = 127.5, which rounds to a value near 128. Green lands at 127.5 as well, and blue at 152.5. Notice red and green end up almost identical at 50%. In fact, at exactly 50% every channel converges on about 127.5, so the image tends toward a flat gray. That is a known property of blending with the inverse, and a useful warning if you were hoping for a "half inverted" look at the midpoint.
Inverting a simple black-on-white graphic gives a white-on-black version, which can be handy for a dark-mode variant of a logo or diagram. Photos of people usually look unnatural when fully inverted, which is expected. Inversion is not the same as a true dark-mode conversion of a screenshot. Colors that were meant to stay recognizable, like a brand red, will become their opposite, so check the result before using it on anything public.
Inverted images can change contrast in ways that make text harder to read. If you use an inverted graphic on a website, test it against its background and consider whether the meaning still comes through for people with color vision differences.
100% produces the classic full color negative; 50% blends halfway between the original colors and their full inversion, producing a more muted, partial shift rather than the extreme negative look.
No -- only the red, green, and blue color channels are inverted; the alpha (transparency) channel is left unchanged.
At 50% intensity each channel is blended halfway with its opposite, which moves all channels toward the same middle value, so the image loses much of its color and contrast.
At full intensity, yes in principle, since the second inversion reverses the first. Saving and reloading a compressed format can add tiny differences.
No. The effect is applied to the whole image. For a partial effect, use an editor that supports selections or masks.
