What is auto white balance?
White balance corrects the color temperature of a photo so whites look white instead of yellow or blue. This tool uses deterministic histogram analysis — gray-world and white-patch heuristics — rather than AI, so results are instant and fully explainable.
After auto-correction you can fine-tune temperature, tint, exposure, contrast, and saturation with live sliders. An RGB histogram readout shows the before and after distribution so you can see exactly what changed.
How to auto white balance
- Drop or click to choose an image.
- Tap Auto correct to apply white balance + exposure correction.
- Fine-tune with the temperature, tint, exposure, contrast, and saturation sliders.
- Compare the before/after and download.
Frequently asked questions
Is this AI?
No. Correction uses deterministic histogram analysis (gray-world and white-patch), so it is fast, explainable, and has zero per-call cost.
Can I adjust manually too?
Yes — temperature, tint, exposure, contrast, and saturation sliders all update the preview live after auto correction.
Is my image uploaded?
No. All correction runs locally in your browser.
