JPG Brightness & Contrast
Fix dark, flat or dull JPEG photos with live sliders, in your browser
Rescue dark, flat or dull JPEGs
Not every photo comes out of the camera looking its best. Shots taken indoors or at night can be too dark, an overcast day leaves images looking flat, and some pictures simply lack punch. Adjusting brightness lifts or lowers the overall exposure, contrast separates the lights from the darks to add depth, and saturation controls how vivid the colors are.
Drag the sliders and watch the photo respond live, so you can dial in a natural correction or a bolder look. When it is right, download the adjusted JPEG. All the processing happens in your browser.

What each control does
Brightness
Raises or lowers the overall light in the image, the quickest fix for a photo that is too dark or slightly washed out.
Contrast
Increases the gap between the darkest and lightest areas to add depth, or lowers it to soften a harsh image.
Saturation
Makes colors more vivid or more muted, from a subtle boost to a fully understated tone.
Frequently Asked Questions
What do the brightness and contrast sliders do?
Brightness shifts the whole image lighter or darker, while contrast widens or narrows the difference between shadows and highlights to control how much depth the photo has.
Can I recover a photo that is too dark?
Often, yes. Raising brightness and adding a little contrast can bring back a dim photo, though detail lost to complete darkness cannot be invented.
Can I change the color intensity?
Yes. The saturation slider makes colors richer or more muted, which is useful for reviving a flat image or toning down an oversaturated one.
Does adjusting reduce quality?
The edit is applied cleanly and saved at high quality, so the only change is the correction you made.
Is my photo uploaded?
No. Every adjustment happens in your browser, so your image never leaves your device.
