About the Image Inverter
What is an image inverter?
An image inverter flips the colors in a picture to their opposites. The classic result is a negative: white turns black, a blue sky turns orange, and light photos go dark — exactly like the negatives that used to come back with film prints. Drop in a JPG, PNG, WebP or GIF and this tool inverts it on the spot, right in your browser, then lets you drag a divider to compare the result against the original before you download it.
We took it well past a plain negative. Invert lightness swaps light for dark while keeping each color's hue, which is the trick you want when you're adapting artwork for a dark theme and don't want your blues turning orange. Grayscale drops the color entirely, the channel toggles let you invert just the red, green or blue, and brightness, contrast and saturation sliders let you dial the result in. Because everything is processed on your device with the HTML canvas, even large or sensitive images stay completely private.
How to Use This Tool
- Add an image. Click Select image, drag a file onto the drop zone, or paste one straight from your clipboard. No image handy? Hit Try a sample.
- Pick an inversion type. Choose Negative, Invert lightness or Grayscale — the preview updates instantly.
- Fine-tune it. In Negative mode, turn individual R, G and B channels on or off. Use the Strength slider to blend toward the original, and the Brightness, Contrast and Saturation sliders to polish the look.
- Compare. Drag the divider, or switch between Compare, Result and Original with the view toggle.
- Save it. Download as PNG, JPG or WebP, or copy the result straight to your clipboard.
Common Use Cases
- Creating dark-mode assets: Turn a black logo on white into a white logo on black in one click, no design software needed.
- Digitizing film negatives: Invert a scanned negative to recover the positive image, then tune the brightness and contrast.
- Accessibility checks: See how a screenshot or interface looks with inverted colors, the way some users browse.
- Artistic effects: Combine partial strength, single-channel inversion and saturation for surreal, high-contrast looks.
- Prepping graphics: Quickly flip an icon or diagram to sit on the opposite background.

Frequently Asked Questions
What does inverting an image do?
It replaces every pixel's color with its opposite by subtracting each red, green and blue value from 255. Pure white (255, 255, 255) becomes pure black (0, 0, 0), and a color like orange becomes blue. The overall effect is a photographic negative of your original image.
Does it keep transparency in PNG images?
Yes. Only the color channels are inverted, so the transparency (alpha) of a PNG is preserved — a transparent logo stays transparent, just with flipped colors. If you export as JPG, which has no transparency, any see-through areas are filled with white.
What's the difference between Negative and Invert lightness?
Negative flips the raw red, green and blue channels, so hues change — blue becomes orange. Invert lightness only swaps light for dark while keeping each pixel's hue, so a dark blue becomes a light blue. Use Negative for a true film-style negative, and Invert lightness when you want to flip a design for dark mode without changing its colors.
Is there a limit on image size?
There's no fixed limit. Because the work happens in your browser, very large images use more of your device's memory, but typical photos and screenshots are inverted instantly. If a huge image feels slow, resize it first and it will process in a snap.
Are my images uploaded anywhere?
No. The whole process runs locally with JavaScript and the HTML canvas. Your image is never sent to a server, stored or seen by anyone, and the tool keeps working even if you go offline after the page loads.
