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.
Trim first, compress once, and check your organization's current Outlook and Exchange policies. Attachment behavior can vary by account and administrator settings.
