About Invert Image Colors
The Invert Image Colors tool replaces every colour in a picture with its exact opposite, turning blacks to whites, reds to cyans and creating the classic photographic-negative effect.
Drop in a JPEG, PNG, WebP or GIF and it is decoded, inverted and previewed entirely inside your browser using the Canvas API.
Inversion is more than a novelty filter.
It is the quickest way to read scanned film negatives as positives, to flip a light UI mockup into a dark one for a quick contrast check, or to make faint detail in X-ray-style scans and astrophotography pop.
Because the maths is a simple per-channel "255 minus value", the result is perfectly reversible — invert a second time and you are back exactly where you started, with no quality loss.
This tool also gives you a strength slider, so instead of a hard negative you can dial in a partial, solarized blend between the original and its inverse for a more stylised look.
The alpha channel is always left untouched, so transparent PNGs stay transparent.
Every step runs on your own device, which means nothing is uploaded, stored or logged, and the tool keeps working offline once loaded.
When the preview looks right, download a lossless PNG.
FAQ
Is my image uploaded anywhere?
No. The picture is decoded and inverted with the Canvas API inside your browser, so it never leaves your device.
Can I undo the inversion?
Yes. A full inversion is perfectly reversible — running the tool again on the result returns the original colours exactly.
Does it keep transparency?
Yes. Only the red, green and blue channels are flipped; the alpha channel is preserved, so transparent areas stay transparent.
