The inversion happens instantly. You can see the negative of your image right away.
Adjust if needed
Some options let you invert individual color channels (R, G, B) for more specific effects.

When would you actually use this?
Good question. More often than you think, honestly. The most common practical use is dark mode work. If you have a UI screenshot or a design asset that looks great on white but you need to see how it holds up on a dark background, inverting gives you a fast approximation without rebuilding anything. It is not perfect, but it is instant.
Accessibility testing is another big one. Inversion is basically what high-contrast mode does on Windows and macOS for users with visual impairments. If your inverted image still reads clearly, it is a good sign the contrast and layout hold up in extreme viewing conditions.
Old film photographers will recognize this immediately. Film negatives are literally inverted images. You can scan a physical negative, drop it here, invert it, and get the positive back. Works surprisingly well for standard color negatives, less perfectly for slides or cross-processed film.
The math behind it (it is simpler than you expect)
Each pixel in an image has three color channels: red, green, and blue. Each channel is a number from 0 to 255. Zero means none of that color, 255 means full intensity. A pure red pixel is 255, 0, 0. A mid-gray pixel is 128, 128, 128.
To invert, you subtract each value from 255. So 255 becomes 0, 0 becomes 255, 128 stays 128 (roughly). A bright red pixel becomes a dark cyan pixel. A pure white pixel becomes pure black. That is the whole operation. It runs on every pixel in your image and takes about a millisecond in your browser.
The creative applications are genuinely fun. Inverted portraits look like something from a sci-fi film. Inverted landscapes turn a blue sky orange and brown earth blue, which looks like a completely different planet. Some graphic designers keep inverted versions of logos for use on dark backgrounds, since the inversion effectively gives you a matching contrast version without redoing the design from scratch.
One thing inversion does not do: it does not change brightness perception. A photo that is too dark will still be too dark after inversion, just with flipped colors. If you want to fix exposure, you need a different tool.
