Each channel is replaced by 255 minus itself. That is the whole operation, and it is exactly reversible — run a negative through this page a second time and you get the original back, pixel for pixel, as long as you export to PNG.
It is the same arithmetic a photographic negative performs optically, which is why scanning film and inverting here gets you a usable positive. It is not colour correction, though: real film carries an orange base mask that inversion alone leaves as a blue cast.
three steps
JPG, PNG or WebP. Scans of film negatives work as well as ordinary photos — the operation does not care what the image is of.
Inversion happens on the decoded pixels as soon as the file loads. There is nothing to adjust, so the preview is simply the result.
Export as PNG when you plan to invert again or edit further, since JPG would add compression artifacts to every round trip.
quick answers
No. It inverts the red, green and blue channels and nothing else. For grain, colour shifts and faded contrast, the photo filters page has vintage and faded presets that are actually doing that job.
Inverting gets you most of the way. Colour negative film has an orange base that survives inversion as an overall blue cast, so finish with the warm and cool tone tool to neutralise it.
Yes, exactly, provided you export to PNG. 255 minus 255 minus x is x. Round-tripping through JPG instead adds compression loss on each pass.
No. Transparency is left alone, so a transparent PNG keeps its cut-out edges and only the visible colours flip.
Inversion preserves contrast rather than adding it. A flat source gives a flat negative — raise contrast on the original first if you want the effect to read strongly.
No. Inversion runs locally in your browser and the page works offline.
