Adjust an image's brightness, contrast, color balance, and saturation right in your browser — drag a slider or apply a one-click preset, then download the result. Nothing is uploaded; the whole edit runs on your device.
What this tool does
It re-grades a photo: make it darker or brighter, shift the color tone warm or cool, boost or mute the colors, or apply a quick effect like black & white or sepia. Every change previews live on the image before you download, and the downloaded file matches the preview exactly.
Sliders
Each slider is neutral at 0. Positive values push one way, negative the other.
| Slider | What it changes | Reach for it when |
|---|---|---|
| Brightness | Adds/subtracts light evenly | The whole image is too dark or too bright |
| Contrast | Spreads or compresses light vs. dark | The image looks flat or washed out |
| Saturation | Color intensity | Colors feel dull, or you want them muted |
| Temperature | Warm (red) ↔ cool (blue) | The white balance looks off / you want a mood |
| Hue | Rotates every color on the wheel | You want to shift the overall color cast |
| Exposure | Scales tones multiplicatively | You want a photographic dim/lift (vs. a flat shift) |
| Shadows | Lifts or crushes dark tones only | Dark areas are blocked up or too heavy |
| Highlights | Recovers or boosts bright tones only | Bright areas are blown out or too flat |
Brightness vs. Exposure
Brightness shifts every pixel by the same amount, so it can flatten highlights quickly. Exposure multiplies, which keeps more contrast as you darken or lift — closer to how a camera responds. Try Exposure first for photos, Brightness for graphics.
Temperature vs. Hue
Temperature only trades red against blue (white balance / mood). Hue rotates all colors together, so reds can become greens. Use Temperature for a natural warm/cool look, Hue for a stylized color shift.
Presets and effects
Presets set the sliders to a look in one click; you can still fine-tune afterward. Effects are separate color transforms that layer on top of the sliders.
| Preset | Look |
|---|---|
| Original | Resets everything to neutral |
| Vivid | Punchier — more saturation and contrast |
| Warm | Golden, warmer tone |
| Cool | Cold, bluer tone |
| Vintage | Faded film — softer contrast, warm cast |
| Darken | Dimmer |
| Brighten | Lifted |
| Effect | Result |
|---|---|
| B&W | Black-and-white (grayscale) |
| Sepia | Warm brown-toned |
| Invert | Photo negative |
How to use it
- Drop an image (PNG, JPG, or WebP) onto the tool.
- Click a preset for a quick starting look, or an effect like B&W.
- Fine-tune with the sliders — the preview updates as you drag.
- Click Download to save the adjusted image in its original format.
Example: a flat, bluish indoor photo → apply Warm, nudge Contrast to +15 and Saturation to +10 → a warmer, punchier shot, downloaded at full resolution.
Private by design
The image never leaves your browser. There's no upload, no account, no watermark, and no size cap beyond what your device can handle — because all the pixel work happens locally.
