Brighten Dark Photos & Documents

Fix poorly lit images by quickly adjusting brightness and contrast. Get clear, readable results instantly.

How to Brighten Images

This completely private, browser-based tool allows you to correct lighting issues perfectly without uploading your photos to a server.

  1. Upload Image: Select a JPG or PNG from your computer.
  2. Adjust Lighting: Use the Brightness and Contrast sliders to selectively fix dark shadows, or flatten out glaringly bright documents.
  3. Toggle Color: Use the Black & White (Grayscale) slider to strip out color noise, which is especially useful before performing OCR on scanned documents.
  4. Export: Click Download Final Image to render the CSS-filtered canvas and download the high-quality corrected photo locally.
