Open I Love To Edit Image Histogram, drop in a photo and read the chart. Peaks on the left mean dark tones, on the right bright tones. The stats show how many pixels are clipped to pure black or white.
A histogram shows how many pixels a photo has at each brightness. Photographers use it to check exposure: a pile-up at the right edge means blown highlights, at the left edge crushed shadows.
See luminance or each red, green and blue channel, with mean, median and the percent of clipped pixels.
How to use the Image Histogram Viewer tool
- Add an image: Drop a photo.
- Read the chart: Switch between luminance, RGB and single channels.
- Check clipping: See the percent of pure black and white pixels.
- Save: Download the histogram as PNG if you need it.

- RGB and luminance: All channels, overlaid or one by one.
- Clipping stats: Percent of crushed shadows and blown highlights.
- Mean and median: Overall brightness numbers.
- Export: Save the chart as an image.
Tips for the best result
- A good exposure usually spreads across the chart without big spikes at the edges.
- High-key photos lean right on purpose; that is fine.
- Fix exposure with Photo Filters, then check again.
