Why use this online tool
True white-balance shift
Adjusts only the red and blue channels (green stays put) - the same maths as camera white-balance. Cleaner than naive 'tint' filters that shift every channel.
Live preview
Drag the slider and see the result update instantly. No 'apply' click - find the exact value that works for your photo, then save.
100% browser-side
The adjustment runs on a Canvas in your browser. Your photo never leaves your device - no upload, no server, no privacy risk.
Free, no watermark
Unlimited adjustments, no signup, no overlay on the output.
When to use it
- Indoor photos under cool fluorescent / LED light - drag right to add warmth
- Outdoor portraits at midday with harsh blue cast - warm them by +20
- Tungsten / incandescent indoor scenes that came out too orange - drag left
- Travel photos where the wrong white-balance preset got baked in
- Editorial / fashion shoots aiming for a 'cool blue' or 'golden warm' aesthetic
Frequently asked questions
- Does this upload my photo to a server?
- No. The adjustment runs entirely in your browser using direct ImageData pixel manipulation. Your image never leaves your device.
- Temperature vs the warm / cool filter - which one?
- Our warm and cool filters are presets at fixed strengths. The temperature slider lets you dial anywhere from -100 (very cool) to +100 (very warm) in 1-step increments. Use the slider when you need fine control; use the presets for one-tap looks.
- Why doesn't the green channel change?
- Real-world white-balance affects mainly the warm-cool axis (R-B), not the green-magenta axis. Camera white-balance controls work the same way - the 'tint' (green-magenta) is a separate control that's rarely needed. We expose the cleaner R-B-only version here.
- Can I fix a strongly-blue underwater photo?
- Partially - dragging right to +60-80 will warm up most of the cast. For severe cases (blue swallows everything), our AI editor has a smarter underwater white-balance tool that does per-pixel correction.
- Can I reset to the original?
- Yes - drop the slider to 0 (or whichever value means 'no change' for this control) to see the original. The source is never modified - the tool always operates on a copy.
- Can I stack multiple adjustments?
- In this widget, one slider at a time. For stacked edits (e.g. brightness + contrast + saturation), use our AI editor where multiple adjustments live side-by-side as non-destructive layers.
