Change Image Exposure Online Free
Runs 100% in your browser — your files never leave your device.
Fix a backlit subject, recover detail in a dim indoor shot, or bring down an overexposed sky. Exposure is applied as a tone curve, so bright and dark regions respond the way a camera sensor would. The correction stays in your browser.

About this tool
How the exposure curve works
Exposure follows the way a camera sensor responds to light. Raising it lifts mid-tones and shadows strongly while protecting pure highlights; lowering it deepens them the same way. The result mimics re-shooting with a different aperture rather than a flat brightening.
When to reach for it
Reach for exposure on backlit portraits, dim indoor shots, and skies that blew out in sunlight. It handles bigger corrections than the brightness slider while keeping the image looking photographed rather than processed.
Tips for the best result
Correct in the direction of the mistake: underexposed shots tolerate strong positive exposure well, while blown-out highlights cannot be recovered by any slider. If shadows turn noisy after a big lift, follow with light denoise.
Frequently asked questions
What does the EV-style scale mean?
EV stands for exposure value — the stops a photographer counts on a camera. Each step doubles or halves the light, so +1.0 is a full-stop increase, using the same vocabulary your camera used when it took the shot.
Will the original file change?
No — the exposure effect is applied to a working copy in memory. Your original file stays untouched on your device, and the download is a brand-new file.
Which formats and sizes work?
JPG, PNG, and WebP files up to 50 MB. The result downloads in the original format with dimensions unchanged.
Can exposure recover detail from a pure black shadow?
Only if the data exists. Pixels at pure black carry no information to lift. When detail matters, expose slightly bright when shooting, then pull the image down here — recovering highlights never works as well as lifting shadows.
