Off: full color inversion (photo negative). On: invert luminance only, preserving hues.
AT USE Invert Colors lets you flip every pixel in any photo or graphic to its mathematical color opposite — creating an instant photo negative effect. Toggle grayscale-only mode to invert only pixels with equal red, green, and blue values while leaving color areas unchanged, ideal for flipping black-and-white elements. Transparency in PNG and WEBP files is preserved automatically. Supports JPG, PNG, WEBP, AVIF, BMP, TIFF, and HEIC up to 20 MB. Processing runs entirely on the server — nothing is stored after download.
Common use cases
- Create a photo negative — Invert a scanned photo to produce a digital negative, matching the look of analogue film negatives for darkroom-style effects.
- Prepare masks for design tools — Flip a white-on-black mask to black-on-white (or vice versa) before importing into Photoshop, Figma, or Canva.
- Dark-mode UI mockups — Quickly approximate a dark-mode version of a UI screenshot by inverting colors for a fast visual comparison.
- Flip grayscale images — Use grayscale-only mode to invert a black-and-white illustration or chart without altering any surrounding color tones.
Frequently asked questions
What does inverting image colors do?
Inverting replaces each pixel's color with its mathematical opposite on the color spectrum — bright areas become dark, dark becomes bright, and each hue shifts to its complement. The result is a photo negative effect, similar to analogue film negatives. Designers use it for mask creation, dark-mode mockups, and creative effects.
What is the difference between full inversion and grayscale inversion?
Full color inversion (the default) flips every channel — red, green, and blue — producing a classic photo negative. Grayscale inversion only inverts pixels where red, green, and blue are equal (true grayscale pixels), leaving colored areas unchanged. Use grayscale inversion to flip a black-and-white image without altering any surrounding color tones.
What image formats can I invert?
The tool accepts JPG, PNG, WEBP, AVIF, BMP, TIFF, and HEIC files up to 20 MB. Transparency in PNG and WEBP is preserved — the alpha channel is not inverted. Output is delivered in the same format as the original.
Does inverting colors affect image transparency?
No. For PNG and WEBP files with an alpha channel, only the RGB values are inverted — the alpha channel is left unchanged. Transparent areas stay transparent and semi-transparent edges remain intact.
Can I use color inversion for dark-mode UI prototyping?
Full color inversion is a quick way to generate a dark-mode proof of concept from a light-mode screenshot — bright backgrounds flip to dark and light text becomes dark. For production assets, use per-element dark-mode CSS; for fast visual mockups, inversion works well.
