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.
Browser compression can be convenient for short and medium iPhone clips. Long 4K recordings may exceed mobile memory, so trim first or use a computer when the browser cannot finish.

Local-first
Privacy-aware, browser-based video trimming and compression
CreatorZip is designed for local, browser-based trimming and compression. When browser processing is available, you can remove unwanted time from the beginning or end and compress the video on your device.
No sign up is required to start compressing videos during launch access.
FAQ
Can I compress an iPhone video without an app?
Yes, when Safari supports the source codecs and the device has enough available memory, CreatorZip can process the video in the browser.
Why does a long iPhone video stop processing?
Long, high-resolution, or high-frame-rate clips can exceed mobile browser memory. Trim the clip, close other tabs, or process it on a computer.
Can I compress an iPhone screen recording?
Yes. Screen recordings are supported when Safari can decode the file and the device has enough memory.
Does CreatorZip upload my Photos video?
No. Supported compression is designed to run locally in the browser.
