What is Image Inverter?

Invert image colors (negative). Create a photographic negative by inverting every color channel. Reverse dark-on-light screenshots for dark docs, or invert scanned negatives. A color-inverted copy keeping original dimensions and alpha.

All processing happens locally in your browser. Your images are never uploaded to any server.

Key Features

  • Per-channel RGB inversion (true negative effect)
  • Optional luminance-preserving mode for dark-mode screenshots
  • Alpha channel untouched

Common Use Cases

  • Creating negative versions of black and white line art for screen printing
  • Inverting scanned documents or film negatives into positive images
  • Generating color-inverted variants for artistic effects and design exploration
User Guide

How to use this tool

The Image Inverter creates a photographic negative of any image by flipping every red, green and blue channel value. Photographers use it to preview film negatives; designers use it to explore contrast alternatives; accessibility engineers use it to check for hidden color issues.

How to use it

Drop an image onto the upload zone. The tool loops through every pixel and computes 255 - value for each of the red, green and blue channels while leaving the alpha channel untouched. This is exactly the mathematical definition of a color negative.

The inverted output appears next to the source for visual comparison. Download it as a lossless PNG.

  • Precise per-pixel channel inversion
  • Preserves alpha transparency
  • Instant preview alongside the source
  • Lossless PNG output

Creative and technical uses

Inverting a diagram or a whiteboard photo often produces a striking dark-mode variant that reads well on OLED displays. Inverting typographic posters can create arresting alternative layouts for social media A/B testing.

For film photographers scanning negatives at home, inversion is the first step toward a positive image. Follow up with color correction to tune the white balance and remove the characteristic orange base cast of color negative film.

Frequently Asked Questions

Does it affect transparency?

No — alpha is preserved; only RGB channels are inverted.

Will inverting twice return the original?

For 8-bit images yes, because inversion is its own inverse.

What does color inversion do?

Each channel value is reversed: 0 becomes 255, dark becomes light, and each hue shifts to its complementary color on the color wheel.

Can I invert only part of the image?

Currently the inversion applies to the entire image. For partial effects, use the crop or pixelate tools in combination.

Is inversion lossless?

Inversion itself is pixel-perfect, but re-encoding to JPG may introduce slight compression artifacts. Use PNG or WebP lossless for exact results.

Is this tool free to use?

Yes. This tool is completely free with no sign-up, no watermarks, and no daily limits. All processing runs locally in your browser.

Is inverting the same as converting to negative film?

For monochrome yes. For color film there is an additional orange mask that also needs correcting after inversion.

Can I selectively invert only some pixels?

Not directly. Combine this with the Palette Reduce or Grayscale tools for stylized effects.
