Image Color Inverter
Creates a color-inverted (negative) version of images by inverting all pixel values. Each color channel is subtracted from its maximum value (255), effectively creating a photographic negative. Uses wasm-vips for precise pixel-level inversion.
What is it used for?
- Creating photo negatives for artistic effects
- Inverting scanned film negatives to positive images
- Generating inverted versions for accessibility (dark mode)
- Creating dramatic visual effects for design projects
- Highlighting details that are hard to see in the original
Step-by-Step Guide
- Click the upload area or drag and drop your image
- Choose your output format (PNG, JPEG, WebP, or AVIF)
- Click Convert to invert the colors
- Preview the inverted result
- Click Download to save the result
How it works
Upload an image and click Convert. wasm-vips inverts every pixel value (new = 255 - original), creating the color negative. Download in your preferred format.
Tips & Best Practices
- Inverting a scanned film negative produces a positive image
- Double inversion restores the original image exactly
- Inverted images can reveal hidden details in very dark or bright areas
Frequently Asked Questions
How does color inversion work?
Each RGB channel value is subtracted from 255. So white (255,255,255) becomes black (0,0,0), red (255,0,0) becomes cyan (0,255,255), and so on.
Can I invert only specific colors?
This tool inverts all channels uniformly. For selective color manipulation, you would need a more advanced image editor.
Is inverting twice identical to the original?
Yes, applying inversion twice returns the image to its original state. Each pixel: 255 - (255 - original) = original.
Privacy & Security
This tool uses wasm-vips (libvips compiled to WebAssembly). The WASM binary (~5MB) is downloaded on first use and cached by your browser. All image processing happens locally on your device - your images are never uploaded to any server. This makes it safe for sensitive, private, or confidential images.
