Image Inverter / Negative
Free online image inverter. Convert any JPG, PNG, or WebP to its colour negative instantly. Useful for film scans, dark-mode assets, and art. 100% private.
How to use

See the Inverted Result — The tool subtracts every red, green, and blue channel from 255 — producing a photographic negative.

Free Online Image Inverter (Photo Negative)
Convert any image into its colour negative directly in your browser. Upload a JPG, PNG, WebP, or GIF and instantly get the inverted version — every pixel's red, green, and blue channels subtracted from 255.
Why Invert an Image?
Recover the positive image from a scanned film negative
Create dark-mode versions of light icons
Produce dramatic artistic effects
Decode visual puzzles or X-ray-style imagery
Generate alternate poster designs
How It Works
The tool uses the HTML5 Canvas API: it draws your image into an off-screen canvas, reads every pixel's RGBA values, replaces each colour channel with 255 - value, and renders the result back. The alpha (transparency) channel is preserved.
Privacy
All processing is local. Your photos never leave your device.
It replaces each pixel's RGB values with their complement (255 - value). Whites become black, reds become cyan, and so on — producing a photographic-negative effect.
Is this the same as a film negative?
Visually yes — the colour relationships flip exactly like film negatives. Film negatives also have an orange mask, which this digital invert does not add.
Can I invert a photo and back?
Yes. Inverting an already-inverted image gives you back the original — the operation is its own inverse.
Is my image uploaded?
No. The image is processed entirely in your browser using the Canvas API. Nothing is sent to any server.
