How does color inversion work mathematically?

In 24-bit RGB color space, each red, green, and blue color channel (0–255) is subtracted from 255. For instance, pure black (0, 0, 0) becomes pure white (255, 255, 255).

Can this tool be used to view scanned 35mm film negatives?

Yes! If you scan analog film negatives, uploading them here and enabling the Invert tool reveals the true positive photograph.

Is there any compression or quality reduction?

No. Exporting as PNG preserves the exact original resolution and lossless pixel quality.

Are my uploaded pictures stored anywhere?

No. The image is loaded into your browser’s temporary memory and never transmitted over any network.

Can I invert transparent PNG logos and icons?

Yes. Color inversion affects color channels while preserving alpha transparency channels intact.
