Invert Image Colors Online
This tool inverts every pixel in your image, replacing each color with its exact opposite to produce a photo negative. Black becomes white, red becomes cyan, and so on across the whole image. It runs entirely in your browser, so your picture is processed on your own device and never uploaded.

When to invert an image
Inverting colors has more uses than it first appears. The most literal is creating a photo negative or previewing a scanned film negative as a positive, so you can tell what the frame contains before a full conversion.
It is also handy for accessibility and dark-mode design. A black-on-white diagram or chart often becomes a clean white-on-dark graphic after a single inversion, which is far quicker than redrawing it. Artists use inversion too, as a starting point for surreal color effects or to check the tonal balance of an image with fresh eyes.
How the inversion works
Every pixel is made of red, green, and blue channels, each ranging from 0 to 255. To invert, the tool subtracts each channel value from 255, so a bright pixel becomes dark and a warm color becomes its cool complement.
All of this happens on a canvas inside your browser using your device's own processing. Nothing is sent to a server, which makes it safe for private scans, work-in-progress artwork, or any image you would rather keep off the internet.

Frequently asked questions
What does inverting colors actually do?
It replaces every pixel value with its opposite on the 0 to 255 scale, so a value of 30 becomes 225. The result is a color negative, the same effect you see on old photographic film.
Can I use this to read a scanned film negative?
Yes. Inverting a scanned negative gives you a rough positive preview so you can see the image, though a dedicated film workflow will handle color casts more accurately.
Does inverting twice return the original?
Yes. Inversion is symmetric, so inverting an already inverted image restores the original colors exactly.
Will inverting reduce my image quality?
No. The operation only remaps color values and does not add compression on its own, so detail and sharpness are preserved.
