Frequently Asked Questions

How much should I increase brightness for a dark photo?

Start with +30 to +50 brightness. If the image looks washed out, increase contrast by +20 to +30 to restore depth. Avoid pushing brightness above +80 as it removes detail in bright areas.

What does contrast do to an image?

Contrast increases the difference between the darkest and lightest parts of an image. Low contrast makes images look flat and grey. High contrast makes them more punchy and dramatic.

What is saturation?

Saturation controls the intensity of colours. Increasing saturation makes colours more vivid. Decreasing it makes colours more muted. Setting it to minimum gives a grayscale effect.

Can I fix an overexposed photo?

Yes. Reduce brightness by -20 to -40 and increase contrast slightly to recover detail in overexposed photos.

Is this tool free?

Yes, completely free. No account needed.

Fix Dark or Washed-Out Photos Online

Poor lighting is the most common reason for disappointing photos. Whether you took a photo indoors without enough light, or the sun was behind your subject causing underexposure — our free brightness and contrast tool can rescue these images in seconds. Used by photographers, bloggers, and social media creators across the USA and UK.

Improve Product Photos for Ecommerce

Product photos taken on a white background often need a contrast boost to make the product pop. Increase contrast by +20 to +30 and add a small saturation boost to make product colours appear more accurate and appealing. This is a common technique for Shopify, Amazon, and Etsy sellers.

Brightness and Contrast for LinkedIn and CV Photos

Professional headshots sometimes appear too dark or flat when uploaded to LinkedIn or used in job applications. A small brightness boost (+15 to +25) and slight contrast increase (+10 to +15) can make a significant difference to how professional your profile photo looks.
