Why Cut Video Files Locally in Your Web Browser?

Video files are heavy, often measuring hundreds of megabytes or gigabytes. Traditional online video trimmers require you to wait ten minutes uploading the entire video to their server, wait in a processing queue, and then wait again to download the trimmed excerpt.

OnlyFiles bypasses network bottlenecks completely. Using HTML5 MediaStream and MediaRecorder APIs, your browser directly reads the video frames from local storage and saves your desired excerpt in real time.

Zero Network Latency

No waiting for gigabytes to upload over slow internet connections. Processing begins instantly.

Complete Confidentiality

Personal family clips, internal product demos, and private footage never leave your device.

No Forced Watermarks

Your exported video is 100% clean and unbranded with zero overlay graphics or promotional tags.

Free & Unlimited

Trim as many clips as you need without daily file quotas, subscription popups, or limits.

Frequently Asked Questions

Can I trim iPhone video files (.MOV)?

Yes. Modern browsers natively decode MOV and MP4 video containers recorded from iOS and Android smartphones.

Why does the exported file use .webm?

WebM is the open standard video container that modern browsers can encode entirely in-memory without proprietary native operating system dependencies.
