Image Invert Tool
Flip the colours of an image. The classic negative turns black into white and every colour into its opposite. The brightness-only mode is smarter: it turns light backgrounds dark and dark text light, but keeps a red logo red and a blue chart blue – perfect for screenshots, diagrams and documents in dark mode. Single-channel inversion is there for creative effects and technical tasks.

Image Invert Tool FAQ
What is the difference between the two main modes?
A negative inverts red, green and blue separately, so hues change to their opposite (red becomes cyan). Brightness only inverts the lightness and keeps the hue and saturation.
Can I convert scanned colour negatives?
A simple inversion gives a rough positive with a strong colour cast, because colour film has an orange base. Correct the cast afterwards with the temperature and tint tools.
Is transparency inverted?
No. Transparent areas stay transparent, so icons and logos can be inverted cleanly.
Does inverting twice restore the original?
Yes, for the negative and channel modes. Brightness-only can differ very slightly due to rounding.
Which formats can I use?
JPG, PNG, WebP, GIF (first frame), BMP and AVIF in; JPG, PNG or WebP out. PNG and WebP keep transparency; JPG gets a white background.
Are my images uploaded?
No. The images are processed in your browser and never leave your device.
Inverting colours
Inverting an image subtracts every colour value from its maximum. In the RGB model, white (255, 255, 255) becomes black, and pure red (255, 0, 0) becomes cyan (0, 255, 255). The result is a photographic negative, the form in which film records an image.
For screen graphics, a plain negative is often not what you want. A light screenshot inverted this way gets a dark background, but its accent colours flip too: a green success message turns purple and a company logo changes colour. The brightness-only mode converts each pixel to hue, saturation and lightness, inverts only the lightness and converts back. Backgrounds and text swap brightness, while colours keep their identity.
Inverting a single channel creates unusual colour combinations useful for art and design, and helps in technical tasks such as examining the content of one channel.
The alpha channel, which stores transparency, is never inverted, so transparent icons remain transparent and can be placed on dark backgrounds right away.
Accessibility is another reason to invert. Some readers with light sensitivity or certain visual impairments find light text on a dark background easier to read, and an inverted copy of a diagram or scanned page can be more comfortable to study on screen.
