When to use this
  • Correcting exposure on a photo that came out too dark or too flat
  • Boosting saturation on a social media photo to make colors pop before posting
  • Fixing an off color cast by nudging the hue slider on a photo shot under odd lighting
  • Giving a batch of listing photos a consistent brightness and contrast look

Free and private. Everything runs on your own device, with no account and no uploads.

Fine-tuning brightness, contrast, saturation and hue is often all a photo needs before it is ready to share, and this tool provides live sliders for each so you can see the effect update in real time without opening a full editor. Photographers correcting exposure and social media users punching up color both find this quicker than a desktop app. Every adjustment is rendered with canvas filters directly in your browser.

Yes, brightness, contrast, saturation and hue can all be combined in a single edit.

Yes, sliders can be dragged back to their default position to undo an adjustment.

Yes, transparency is preserved while color and tonal adjustments are applied to the visible pixels.

The adjustments themselves are non-destructive until export, at which point the format and quality setting you choose determine final file size.

Pro tips
  • ·Make small adjustments to multiple sliders rather than a large push on one, it usually looks more natural
  • ·Increase contrast slightly after boosting saturation, since higher saturation alone can make an image look washed out
  • ·Reset a slider to default if an adjustment looks off, rather than trying to correct it with a different slider
