Levels
Live histogram, three eyedroppers, per-channel. Local processing, nothing uploaded.
Drop an image in and look at the histogram — if both ends are empty, pull the sliders inwards and the wash is gone.
Levels gives you five sliders: input black, midtone, input white, plus output black and output white. A washed-out photo is one whose histogram is empty at both ends; pull the two input sliders in to where the data actually starts and the contrast comes back. The midtone slider (gamma, range 0.1–9.99) controls overall brightness on its own without touching either end. The red, green and blue channels can each get their own black and white points — the most effective rescue for a photo with a colour cast. There are also three eyedroppers — black, grey and white — that set a point with one click on the image; click the grey one on something that should be neutral grey and the cast vanishes on the spot. The Ctrl+L shortcut matches Photoshop. Levels runs as a non-destructive adjustment layer: the original pixels are untouched and the settings stay editable. It all runs in your own browser; the image is never uploaded.
Key features
Live histogram
See exactly where the pixels sit and how much empty space is at each end; switch channel and it shows that channel.
Three eyedroppers
Black, grey and white — one click on the image sets the point. The grey one is the cure for colour casts.
Per-channel
Red, green and blue each get their own black and white points — better at rescuing a cast than adjusting the composite.
Non-destructive
It is an adjustment layer: original pixels untouched, settings editable or deletable at any time.

FAQ
- Why does my photo look washed out?
- Because the histogram is empty at both ends — the black and white points are not spread out, so there is no true black and no true white in the frame. Pull the two input sliders in to where the histogram actually has data.
- What is the difference between Levels and Curves?
- Levels has five sliders and is fast and direct; Curves lets you add control points at any brightness and is finer. Anything Levels does, Curves can do too — but not the other way round, and for everyday wash and brightness fixes Levels is quicker to reach for.
- What is the fastest way to fix a colour cast?
- The grey eyedropper. Click it on something in the frame that should be neutral grey — concrete, a shadow on a white wall, a grey shirt — and the cast disappears immediately. If there is no such reference, switch to the red, green and blue channels and set their black and white points individually.
