Convert images to Base64 encoded strings for embedding in CSS, HTML, or JavaScript. Multiple output formats available.
Compare two images pixel-by-pixel. Multiple comparison modes: side-by-side, overlay, difference highlighting, onion skin, and slider. Perfect for visual regression testing.
Crop and trim images with precision visual selection. Features aspect ratio presets (1:1, 16:9, 4:3), free-form cropping, grid overlays, and pixel-perfect adjustments for professional results.
View the tonal distribution of any image as a histogram chart. See how pixel values are distributed across shadows, midtones, and highlights for each color channel (red, green, blue) and for overall luminance. A handy diagnostic tool for photographers and anyone evaluating exposure.
Quickly assess whether a photo is underexposed, overexposed, or well-balanced.
Compare RGB channels to identify color casts or imbalances.
Check that tonal range uses the full spectrum before sending images to print.
It depends on the image. Generally, a well-exposed photo has a smooth spread of values without hard spikes at either edge. But a high-key portrait or low-key artistic shot will naturally skew one way.
The histogram is read-only — it is a diagnostic tool. Use the Image Filters or Color Grader tools to make adjustments based on what the histogram reveals.
