Why people compress video to 100MB
A 100MB target is useful when the original clip is too large for a strict upload limit, attachment cap, or lightweight sharing workflow.
Fit strict file-size limits
Shrink the file before uploading so you can avoid size errors at the last step.
Keep uploads and attachments lighter
A smaller export is easier to attach, send, and preview across different devices and connections.
Compress locally in the browser
Work on-device when you want a private workflow without moving the source file to a remote editor.
