Frequently asked questions
What is the difference between the three modes?
All colors makes a classic photo negative (red becomes cyan, white becomes black). Brightness only flips light and dark but keeps hues, a dark-mode look. Grayscale negative inverts a black-and-white version.
Does it keep transparency?
Yes in PNG and WebP; only the colors are inverted. JPG has no transparency, so transparent areas become white before saving.
Can I turn a photo negative back into a positive?
Yes. Scanned film negatives invert to positives, though color film has an orange mask, so colors may need further correction in an editor.
Does it change the image size?
No. The output has the same pixel dimensions as the input.
Is my image uploaded?
No. The pixels are processed in your browser.
