Which image formats are supported?

JPEG, PNG, and WebP. The downloaded file keeps the original format and extension.

Is my image uploaded to a server?

No. All inversion happens locally in your browser — your image stays on your device.

What does Strength do?

Strength blends the inverted result over the original. 0% = original image, 100% = fully inverted, and values in between create a softer, more usable effect.

What is Luminance Only inversion?

It inverts brightness while preserving the general hue family. It’s useful when you want a negative-like look but keep colors from becoming too strange.

What do the R/G/B toggles do?

They invert individual color channels (Red, Green, Blue). This can create stylized effects or help with technical workflows.

Invert Image Colors in One Sentence

This tool creates anything from a classic photo negative to subtle “dark-mode” inversions by combining adjustable Strength, Luminance-only inversion, and selective R/G/B channel toggles — all in your browser.

When to Use Color Inversion

Color nversion it’s useful for both creative and practical tasks:

Photo negative / x-ray style effects
Dark mode previews for UI screenshots or graphics
Creative posters & thumbnails (high-contrast, attention-grabbing looks)
Selective channel experiments (glitch / surreal color shifts)
Quick checks on line art, shapes, or contrast (inversion can reveal issues)

If you want a controlled negative that still looks “designed,” use Strength (not just full invert), or try Luminance only.

How to Use

1. Add an image

Drag & drop, paste (Ctrl/⌘+V), or click to select a JPEG / PNG / WebP.

2. Choose your inversion style

You have two main paths:

Luminance only: invert brightness while keeping color family
Channel inversion: invert Red, Green, and/or Blue channels

3. Set Strength

Strength blends inverted pixels over the original:

0% = original
30–70% = subtle/usable (often best for “design”)
100% = full negative

4. Surprise Me (optional)

Controls Explained

Strength (0–100%)

Strength is your realism dial. Full inversion is dramatic, but often too harsh. Blending makes the result more usable.

Common ranges:

20–45%: gentle inversion (great for stylized looks)
50–80%: strong, but still controllable
90–100%: true negative

Luminance only

This option inverts lightness (brightness) rather than inverting each RGB channel directly.

What it’s good for:

keeping colors from becoming wildly unnatural
making “negative-like” looks that still feel cohesive
preserving a sense of the original palette

Tip: Luminance-only at 50–85% Strength often looks surprisingly “premium” compared to raw full-RGB inversion.

Channel toggles (Red / Green / Blue)

With Luminance-only off, you can invert channels individually:

Invert Red: can push images toward cyan-ish shifts
Invert Green: often creates magenta-ish shifts
Invert Blue: can push toward yellow-ish shifts

Why this matters: selective channel inversion can create effects that feel more intentional than a full negative.

Note: If you turn all channels off, nothing changes.

Quick Recipes

Classic negative (photo negative)

Luminance only: off
Channels: R + G + B
Strength: 90–100%

“Designed” negative (less harsh)

Luminance only: on
Strength: 60–90%

Subtle dark-mode vibe

Luminance only: on
Strength: 25–55%

Glitchy color shift (selective)

Try any of these:

Channels: R only or B only
Strength: 45–90%

Or invert two channels:

Channels: R+G (often dramatic)
Strength: 60–100%

Almost-no-change surprise (tiny effect)

Luminance only: on or off
Strength: 5–20%

Good for “something’s different, but I can’t tell why” styling.

Tips for best results

1. Use Strength like a blend knob

Most “good looking” inversion results are not 100%. If the effect feels too aggressive, reduce Strength before changing the mode.

2. Prefer Luminance-only for photos

Full RGB inversion can make skin tones and natural scenes look chaotic. Luminance-only often keeps the image readable.

3. Use selective channels for intentional design

If full negative feels random, try inverting one channel, then adjust Strength. It’s an easy way to get stylized looks without wrecking the whole palette.

4. Watch highlights and text

Inversion flips light and dark. If you’re inverting a UI screenshot or text-heavy graphic:

try Strength 30–60%
check readability on the preview

Common Problems and Fixes

“It looks too harsh.”

Lower Strength
Try Luminance only

“Colors look weird / toxic.”

Use Luminance only
Or invert only one/two channels instead of all three

“Nothing changed.”

Strength may be 0%
Or all channel toggles are off (with Luminance-only off)

How It Works

The tool supports three processing paths:

Full RGB invert (R+G+B) uses a fast invert filter.
Selective channel invert flips only the chosen channels (e.g., R = 255 - R).
Luminance-only converts pixels to HSL, inverts lightness, then converts back — preserving hue and saturation.

Finally, the result is blended over the original according to Strength.
