Image Adjust

This subcategory collects 14 free tools that need no account and correct an image without leaving your browser. It fits a photo that is too dark, a dull scan, a visual that needs warming or an image to clean before publishing. Tools include Brightness and Contrast, Correct exposure, Hue and saturation, Shadows and Highlights, Reduce noise and Blur an Image. Files stay in your browser when the tool page says so.

For a simple fix, start with Brightness and Contrast or Correct exposure. If midtones are blocked, try Gamma correction; if the image looks flat, use Auto contrast or Equalizes histogram. Hue and saturation, Color temperature, Tinting an Image and Channel mixer work on color. Shadows and Highlights recovers detail, Emphasize an image boosts edges, Reduce noise smooths grain, Blur an Image softens and Edit Opacity makes an image partly transparent. Move from simple to fine control.

How to use

  1. Start with Brightness and Contrast or Correct exposure to balance the scene, then look at Gamma correction if the midtones still feel dense.
  2. Recover detail next with Shadows and Highlights, and use Auto contrast or Equalizes histogram only if the image still looks flat.
  3. For color, choose Color temperature, Hue and saturation or Channel mixer depending on whether you fix a cast or a precise shade.
  4. Clean up at the end with Reduce noise, Emphasize an image, Blur an Image or Edit Opacity, comparing before and after to avoid an artificial look.

Frequently asked questions

Which tool should I start with to brighten a photo?

Start with Brightness and Contrast or Correct exposure. They give a first balance without going into curves. If midtones remain too dark, move to Gamma correction. To recover both shadows and highlights, then use Shadows and Highlights.

How do I fix a color cast?

First try Color temperature to warm up or cool down the image. Hue and saturation lets you adjust colors precisely. If needed, Tinting an Image blends a color with the image, and Channel mixer adjusts red, green and blue separately.

Should I correct color before or after light?

Fix light first with Brightness and Contrast or Correct exposure. Then adjust color with Color temperature, Hue and saturation or Channel mixer. Finish with Reduce noise or Emphasize an image. This order prevents you from strengthening a cast before it is corrected.

How do I reduce noise without erasing detail?

Apply Reduce noise carefully, then use Emphasize an image to bring back some edge. If grain remains annoying, try Blur an Image where it suits the image. Check the result at full size before export.
