Adjust Image Color Temperature
Make photos warmer (golden) or cooler (blue) with a Kelvin-style slider. Fix white balance creatively — free tool.
About the Color Temperature
Color temperature shifts the red–blue balance of an image the way a camera's white balance does. Warm up sterile indoor shots with +20 to +40, or cool harsh sunlight with −15 to −30 for a calm, blue-hour mood.
How it works
The filter shifts the balance between red and blue channels across the image: positive values push toward golden warmth, negative toward icy blue, while green stays anchored so skin and foliage keep their character. It's the white-balance control from camera software, running in your tab.
How to use it
Drop up to 10 images, drag the temperature slider while previewing (small moves fix casts; large moves create moods), and process. Download results individually or as a batch ZIP.
Supported formats & limitations
Accepts .jpg, .png and .webp up to 30MB each, 10 per run. This is global — it can't warm only the background — and extreme shifts clip channel peaks. For surgical correction, full photo software still has its place.
Common use cases
Fixing photos shot under tungsten or fluorescent light, warming product shots for cozy marketplaces, cooling tech imagery for a crisp modern feel, and harmonizing a mixed batch of photos shot in different lighting.
Frequently asked questions
How private is Color Temperature?
Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.
Can it open JPG, PNG and WebP files?
The common formats are covered — JPG, PNG or WEBP, each up to 30 MB. Queue them one batch at a time.
How many images can I process at once?
Batch runs take up to 10 files at once (30 MB each). There's no account, no daily quota and no watermark — process as many batches as you need.
Can I fine-tune the result before downloading?
You can adjust Temperature. Results are previewed after processing, so tweak values and re-run until the output looks right.
