Compress Video to a Target File Size

Need a video under an upload or attachment limit? Enter a target size and the tool calculates a practical video bitrate from the clip duration.

WHY USE THIS TOOL

Useful when the limit is a number, not a quality preset

Some portals, email systems and messaging apps reject files above a fixed size. A target-size workflow is faster than guessing CRF values repeatedly.

Enter the limit

Choose the size you want to aim for in megabytes.

Bitrate is calculated

The server uses source duration and audio allowance to derive a practical video bitrate.

Keep some headroom

Container overhead and source complexity mean the result is an estimate, so choose slightly below a hard upload limit.

HOW IT WORKS

How to compress video to a target size

1
Upload a video
Choose a supported video file.
2
Enter the target MB
Use a value below the service limit when you need safety headroom.
3
Compress and download
The tool encodes an MP4 using a duration-aware bitrate target.

Good to know

Target size is approximate, not byte-exact. For a strict 25 MB portal limit, aiming around 23–24 MB provides practical headroom.

QUICK ANSWERS

Target Size Video Compressor FAQ

Will the output be exactly the target size?

Usually it will be close, but encoding complexity and container overhead can shift the final size.

What if I choose a very small target?

The tool enforces a minimum usable video bitrate. Extremely small targets can produce visibly reduced quality.

Does duration matter?

Yes. A longer video needs a lower average bitrate than a short video to fit the same file-size target.
