About the Invert Image Colors

Invert Image Colors flips every pixel to its exact opposite — black becomes white, blue becomes orange — producing a photo-negative effect. The intensity slider lets you apply a full inversion or a partial one, with a live side-by-side preview.

Common uses include turning scanned film negatives back into positives, creating dark-mode versions of diagrams and screenshots, generating striking artistic effects, and improving readability of white-on-black technical drawings before printing.

The inversion runs on the Canvas API entirely in your browser. Files are never uploaded, so scans and screenshots containing private information stay on your device.

Frequently asked questions

How do I invert the colors of an image?

Upload the image and the inverted preview appears immediately at 100% intensity. Adjust the slider if you want a partial effect, then click Download to save the result.

What happens when you invert an image?

Each color channel value is flipped around its midpoint: 255 becomes 0, 200 becomes 55. Black turns white, and every color becomes its complement — blue becomes orange, red becomes cyan — like a film negative.

Can I turn a scanned film negative into a normal photo?

Yes — inverting a scanned negative flips it back to a positive image. Color negatives also carry an orange film base, so after inverting you may want to fine-tune with the brightness and contrast tool for a natural result.

Does inverting twice restore the original image?

At 100% intensity, yes — inversion is perfectly reversible: invert the inverted file and you get the original pixels back. Partial intensities blend with the original, so they don't round-trip exactly.

Why invert diagrams or screenshots?

Inverting light-background diagrams creates instant dark-mode versions that are easier on the eyes in presentations. Conversely, inverting white-on-black CAD drawings before printing saves enormous amounts of ink.
