User guide

Overview

Professionally retouch your photos with 16 parameters — brightness, contrast, saturation, temperature, sharpness and more. Includes a live preview and a Before/After split-compare view.

How to use
  1. Upload an image: Drag and drop a file into the drop zone, or click to select one.
  2. Choose a preset (optional): Click one of 12 presets — landscape, portrait, black & white, and more.
  3. Adjust parameters: Fine-tune individual settings with the sliders on the right. Changes apply in real time.
  4. Check the histogram: Use the RGB channel histogram to verify the exposure looks right.
  5. Download: Click the save button when you're done.
Click Auto Enhance to let the tool automatically set optimal brightness, contrast and saturation. Fine-tune further with the sliders afterward.
Key adjustments
  • Exposure: Overall brightness (EV-based)
  • Highlights / Shadows: Adjust bright and dark areas independently
  • Temperature: Shift the color between warm (orange) and cool (blue)
  • Tint: Adjust the green–magenta color bias
  • Vibrance / Saturation: Color intensity — vibrance protects colors that are already highly saturated
  • Sharpness: Edge enhancement (overdoing it increases noise)
  • Vignette: Darken or brighten the edges of the frame
Pushing both sharpness and noise reduction too high at once can work against each other. Adjust them one at a time to find the right balance.
Limitations and notes
  • File size is limited to 20MB, and only one file can be processed at a time.
  • All adjustments are calculated live in your browser, so very large original resolutions may make the sliders feel less responsive.
  • Saving may introduce minor quality loss depending on the compression method of the output format you choose (e.g. JPG).
