A QUICK WALKTHROUGH
How to use this tool
- Choose a JPEG, PNG, or WebP image.
- Adjust warmth, tint, correction strength, and the comparison split.
- Review the preview and download a newly rendered PNG if useful.
Visual correction model
Warmth shifts red against blue; tint shifts red and blue against green. Strength blends that heuristic correction with the source. This is not camera-profile, RAW, ICC, or measured white-balance processing.
Before and after
The split control reveals the original on the left and corrected pixels on the right. The downloaded PNG contains the corrected image without the split line.
Local raster output
JPEG, PNG, and WebP inputs are limited to 20 MB, 10,000 pixels per side, and 40 megapixels. Canvas output does not retain source EXIF, ICC profiles, animation, or original encoding.
GOOD TO KNOW
Common questions
Does it find a neutral point automatically?
No. You choose warmth, tint, and strength by eye.
Is this professional white balance?
No. It is a bounded sRGB preview and raster export.
Is the photo uploaded?
No. Decoding, correction, preview, and export stay in this browser.
