## Overview

Easily adjust the brightness of your videos online. Whether you need to lighten up underexposed footage captured in low light or darken overexposed clips, this tool lets you fine-tune the exposure level from -1.0 to 2.0 and export the result in MP4, WebM, or MKV format.

## Inputs

- **Video File** (file): Select a video file to adjust brightness
- **Brightness Level** (range): Range: -1.0 to 2.0 (1.0 = original, 0.0 = black, 2.0 = twice as bright)
- **Output Format** (select)

## When to use

- When a video recorded in low-light conditions is too dark to see clearly and needs to be brightened.
- When outdoor footage is overexposed or washed out and requires lowering the brightness level.
- When you need to quickly adjust video exposure and convert the output format in a single step.

## How it works

- Upload your video file (up to 500MB) in any standard video format.
- Adjust the brightness slider between -1.0 (completely black) and 2.0 (twice as bright), where 1.0 represents the original brightness.
- Select your preferred output format, such as MP4, WebM, MKV, or keep the original format.
- Process the video to apply the exposure adjustment and download your modified file.

## Use cases

- Enhancing night-time security camera footage to make dark details more visible.
- Dimming overly bright drone footage captured in direct midday sunlight.
- Preparing dark smartphone videos for social media sharing by boosting their exposure.
