Free Online Image Color Inverter
Invert image colors for negatives and creative effects.
100% creates a full negative. Lower values blend the inverted colors back toward the original.
This exchanges red and blue for a cool color shift instead of a true negative.
Alpha transparency is preserved. A 100% inversion is the same effect as a photographic negative; partial values are blended mathematically, not applied as a simple opacity overlay.
About the Image Color Inverter
Inverting an image flips every color to its opposite on the color wheel: black becomes white, red becomes cyan, and green becomes magenta. The effect is most familiar from photographic negatives, but it is also a quick way to create surreal artwork, high-contrast backgrounds, and dark-mode variants of diagrams. This tool inverts JPG, PNG, and WebP images in the browser and lets you choose anything from a subtle tint to a complete negative. No upload is involved, so even confidential screenshots can be processed safely.
Full and partial inversion
At 100 percent, each channel is replaced by its mathematical opposite using 255 − value. At lower
percentages the tool blends between the original and the negative, which is useful for toning down the effect
on portraits or keeping text legible. A setting of 25 to 40 percent often produces an interesting duotone
look without the harshness of a full negative. The preview updates continuously while you drag the slider.
Channel-swap mode
The optional red/blue swap is not a true negative. It exchanges the red and blue channels and leaves green alone, which shifts warm colors toward blue and cool colors toward orange. Combined with partial inversion, it can imitate cross-processed film or a synthetic night-vision palette. Because the operation is deterministic, applying the same settings twice does not return the original unless the inversion amount is zero.
Practical uses
- Restoring film scans: invert a scanned negative before adjusting tone and color.
- Design experiments: generate a dark background from a light diagram in seconds.
- Visibility: make faint pencil sketches or faded documents easier to read.
- Creative edits: use partial inversion as a cheap duotone or poster effect.
Frequently asked questions
Does inversion work on transparent images?
Yes. Only the red, green, and blue channels are changed. The alpha channel is left alone, so transparent areas stay transparent in PNG and WebP output.
Why does a scanned negative still look orange after inverting?
Film negatives have an orange base mask that shifts the colors. A plain inversion cannot remove it completely. After inverting, use the grayscale or color adjustment tools to neutralize the cast.
Can I invert only part of the image?
This page applies the effect to the entire picture. To invert a region, invert the whole image, then combine the result with the original in an editor using a mask, or use the pixelator's selection workflow as a reference for region-based editing.
