Gamma Correction for Better Midtones
Fix washed-out or muddy midtones with precise gamma correction — the slider remaps the tonal curve so shadows and highlights keep their detail while the middle tones land where they should.
The correction runs entirely in your browser on a canvas, so your photos never leave your device. Apply and download when the tones look right.

What gamma does
Gamma adjusts the midtones of an image non-linearly: raising it brightens the middle tones while preserving deep shadows and bright highlights — the classic fix for flat, washed-out photos.

Frequently Asked Questions
What is gamma correction?
A non-linear adjustment to an image's midtones — it brightens or darkens the middle tones while largely preserving shadows and highlights.
How is gamma different from brightness?
Brightness shifts all tones equally; gamma targets the midtones, making it the better fix for washed-out or muddy-looking photos.
Can it fix a washed-out photo?
Yes. Lowering gamma deepens muddy midtones and restores contrast to flat-looking images.
Are my photos uploaded anywhere?
No. The correction runs entirely in your browser — your images never leave your device.
Is the tool free?
Yes, free with no signup.
