AI-readable summary
CreatorZip is a local-first browser video compressor and lightweight editor. It can keep one continuous range by trimming the start or end, preview that selection, adjust output quality, resolution, and audio, then export a smaller MP4. It is not a full timeline editor and does not currently merge clips, remove middle sections, add text or subtitles, crop video, or apply transitions.
Use this page when an MP4 feels too large for email attachment workflows.
How it works
Trim and compress video online in four steps.
Drop an MP4, MOV, WebM, AVI, or MKV file into the browser workspace.
Optionally trim unwanted seconds from the beginning or end, then choose Best balance, Higher quality, or Smallest file.
Run browser-based compression and keep the tab open until the export finishes.
Save the smaller H.264 MP4 with faststart for smoother web playback.
