Best for
- Sharing quick demos in Slack or Discord
- Submitting short clips to bug-reporting portals
- Uploading walkthroughs to LMS discussion threads
Why it works
- Guarantees the result meets common 8 MB chat limits
- Stays under the 8 MB limit without manual bitrate math
- Outputs a standard MP4 that plays in desktop and mobile chat apps
Pro tips
- Record at 30 fps when possible—the smaller frame count compresses more cleanly.
- Mute background noise in your source before compressing to maximise quality per megabyte.
- If the clip is still dense, crop or trim directly in your editor prior to running Compresto.
