How it works
Each red, green, and blue channel is mapped toward its opposite value; alpha is left unchanged. Partial intensity blends the original and inverted channel values.
Output, dimensions, and metadata
Output keeps the original pixel dimensions. Canvas re-encoding usually omits source metadata such as EXIF or IPTC fields; do not rely on metadata preservation. JPEG output is lossy, while PNG is used when the source needs transparency. The exported image follows the browser-decoded visual orientation. Browser Canvas may normalize color behavior, so this is a practical conversion rather than a promise of professional ICC-profile equivalence.
Browser compatibility and limits
The current browser must support JavaScript, Canvas, and native decoding for the selected image. A decode failure is reported without uploading the file.
Files are limited to 25 MB, 40 megapixels, and 12,000 pixels per side. Replace or reset an image to release the prior decoded buffer.
