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.

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

1Upload your video file (up to 500MB) in any standard video format.
2Adjust the brightness slider between -1.0 (completely black) and 2.0 (twice as bright), where 1.0 represents the original brightness.
3Select your preferred output format, such as MP4, WebM, MKV, or keep the original format.
4Process 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.

Examples

1. Brightening Low-Light Smartphone Footage

Vlogger

Background

A vlogger recorded an intro segment in a dimly lit room, resulting in dark, muddy visuals where their face is barely visible.

Problem

The video is too dark to upload to social media, but re-shooting is not an option.

How to use

Upload the dark MP4 video file, set the Brightness Level slider to 1.5 to boost the exposure, and select MP4 as the output format.

Brightness: 1.5, Output Format: MP4

Outcome

The video is significantly brighter, making the vlogger's face clearly visible without losing too much detail, ready for upload.

2. Dimming Overexposed Drone Video

Real Estate Videographer

Background

A videographer captured aerial footage of a property on an extremely sunny day, causing the white roof and concrete driveway to look washed out.

Problem

The highlights are too bright, making the property details look harsh and unprofessional.

How to use

Upload the drone video file, set the Brightness Level to 0.8 to tone down the highlights, and choose to keep the original format.
