Drag the divider in the preview to compare Before and After, and watch the Histogram for clipped highlights or shadows.

Frequently asked questions
Are my photos uploaded?
No. All adjustments are calculated in your browser, and your photos stay on your device.
Do all images in a batch get the same edit?
The slider values are the same for every image. Auto is measured separately for each photo, so each one gets its own levels and color-cast correction.
Will I lose quality or metadata?
The image is re-encoded after editing. PNG adds no compression loss; JPG and WebP use the Quality slider, 90 by default. EXIF data such as camera details and GPS location is not carried over.
What is the difference between Saturation and Vibrance?
Saturation strengthens or weakens all colors equally, down to black and white at -100. Vibrance boosts muted colors more than strong ones, so already vivid areas are less likely to look oversaturated.
Can I edit RAW camera files?
No. Supported inputs are JPG, PNG, WebP, AVIF, GIF, BMP and HEIC. Convert RAW files to JPG in your camera software first.
How do I undo a change?
Click the reset arrow next to a slider's value or double-click its name to set it back to 0, or click Reset all. Your original files are never changed.
