Why use this tool

Common problems

The target size is too small
Choose a larger target size or a lower resolution so enough bitrate remains for playable video and audio.
The URL cannot be imported
Use the original public post URL, or upload a permitted copy of the video file.
Compression takes longer than expected
Target-size mode uses two encoding passes for better size accuracy and can take roughly twice as long.

Frequently asked questions

Which quality should I choose?
Balanced is the best default. High keeps more detail, while Small produces a lighter file.
Will the compressor enlarge a low-resolution video?
No. Resolution choices act as maximum heights and do not upscale smaller sources.
How accurate is target-size mode?
MyToolsNext calculates video and audio bitrates from duration and uses two-pass encoding. Container overhead can make the final size vary slightly.
Are uploaded videos retained?
Uploads and outputs are temporary and expire according to the configured media retention period.
