Invert Image Colors
Swap every colour for its opposite — black becomes white, blue becomes orange — to make a photo negative, flip a dark-mode screenshot to light, or recover a scanned film negative. Processed on your device.

How it works
Inversion subtracts each red, green and blue value from 255, so a pixel at (10, 20, 200) becomes (245, 235, 55). It is exactly reversible — invert twice and you are back where you started — and it never touches transparency, so a PNG logo keeps its cut-out edges. Common uses: turning a scanned negative into a positive, previewing how a dark logo reads on a light background, making a white-on-black diagram printable, or creating a quick x-ray-style effect. One thing inversion is not: a dark-mode converter for photos. Skin and skies come out surreal because their hues flip too; for screenshots and line diagrams, however, it does exactly what you expect.

Frequently asked questions
What does inverting colours actually do?
Each channel becomes 255 minus its value, so light turns dark and every hue turns into its complementary colour: red to cyan, green to magenta, blue to yellow.
Can I use this to turn a film negative into a normal photo?
Yes for black-and-white negatives. Colour film has an orange mask, so the result of a plain inversion has a blue cast — still usable as a preview, but a dedicated scanner profile gives truer colour.
Will inverting a dark-mode screenshot make it light mode?
Mostly. Backgrounds and text swap correctly; coloured icons and images inside the screenshot flip to their complementary colours, so expect a few oddly-tinted logos.
Does it keep transparency?
Yes. Only red, green and blue are changed; the alpha channel is copied through unchanged, so transparent PNGs stay transparent.
Is inverting reversible?
Completely — run the inverted file through the tool again and you get the original colours back (JPG will have gone through one extra save, which is not visible at high quality).
Can I invert only part of an image?
Not here; the whole image is inverted. Crop the area first, invert it, then paste it back in an editor if you need a partial effect.
Is my image uploaded?
No. The pixel maths runs in your browser tab; there is no server involved and nothing is transmitted.
Does it work on GIFs?
It inverts the first frame and saves a still image. Animation is not preserved.
