Maximum file size: 10MB Supported formats: image/jpeg, image/png, image/webp, image/gif, image/bmp, image/tiff

Upload any image file (JPEG, PNG, WebP, GIF, BMP, TIFF) to adjust exposure

-3 0 3

Exposure compensation in EV stops (-3.0 to +3.0). 0 = original, positive = brighter, negative = darker

Choose output format or keep original. PNG recommended for maximum quality

Output quality for lossy formats (JPEG, WebP). Higher = better quality but larger file size

Overview

Easily adjust the exposure of your photos to correct lighting issues or achieve a specific aesthetic. This tool simulates camera exposure compensation, allowing you to brighten underexposed images or darken overexposed ones with precise control over brightness and contrast.

When to Use

  • •Correcting photos that were taken in low-light conditions and appear too dark.
  • •Fixing overexposed images where highlights are blown out or details are lost.
  • •Adjusting the overall mood of an image by shifting the exposure levels before saving in a preferred format.

How It Works

  • •Upload your image file (JPEG, PNG, WebP, GIF, BMP, or TIFF).
  • •Use the exposure slider to set your desired compensation in EV stops, ranging from -3.0 to +3.0.
  • •Select your preferred output format and quality settings if you wish to convert or compress the file.
  • •Process the image to apply the changes and download your adjusted photo.

Use Cases

Recovering details from underexposed smartphone photos taken indoors.
Reducing brightness in outdoor shots to bring back color depth in highlights.
Standardizing the brightness levels of a batch of images for a consistent look.

Examples

1. Brightening a Dark Indoor Portrait

Social Media Manager
Background
A series of photos taken at an evening event turned out too dark to post.
Problem
The subjects are barely visible due to low ambient light.
How to Use
Upload the photo and set the exposure compensation to +1.5 EV to brighten the scene.
Example Config
exposure: 1.5, format: 'original'
Outcome
The subjects are clearly visible with improved brightness and balanced contrast.

2. Correcting Overexposed Landscape

Amateur Photographer
Background
A bright sunny day caused the sky and clouds to look washed out in a landscape shot.
Problem
The image lacks contrast and the highlights are blown out.
How to Use
Upload the image and apply a -1.0 EV exposure adjustment to recover detail in the highlights.
Example Config
exposure: -1.0, format: 'png', quality: 100
Outcome
The sky regains its blue tone and the clouds show more texture and definition.

FAQ

What does the exposure compensation value mean?

The value represents EV (Exposure Value) stops. A positive value increases brightness, while a negative value decreases it.

Can I convert my image to a different format?

Yes, you can choose to keep the original format or convert your file to JPEG, PNG, or WebP.

Does adjusting exposure affect image quality?

Adjusting exposure is a digital process. Using high-quality output settings like PNG or high-quality JPEG will help maintain the best visual results.

Is there a file size limit for uploads?

Yes, the maximum file size for image uploads is 10 MB.

What is the recommended quality setting?

A quality setting of 95 is recommended for a good balance between visual fidelity and file size for lossy formats like JPEG and WebP.
