Why Use a Browser-Based Video Cutter?

Most online video cutters upload your file to a remote server, process it there, then let you download the result. This tool works differently: every byte of your video stays on your device. FFmpeg — the industry-standard video processing engine — runs entirely inside your browser tab via WebAssembly. No account, no upload, no waiting for a server queue.

How this Free Online Video Cutter — Trim MP4, MOV & WebM Instantly works

Cut and trim video files directly in your web browser using FFmpeg WebAssembly — no upload to any server, no installation, and no account required. Ideal for removing unwanted intro or outro segments, extracting a highlight clip, or shortening footage before sharing on Instagram Reels, TikTok, or YouTube Shorts. Supported formats include MP4, MOV, and WebM.

All processing happens client-side on your device. Your video file never leaves your computer, which protects your privacy and eliminates any server-imposed file size restriction. The tool uses smart stream copy whenever the container format allows it, extracting the selected segment without re-encoding and preserving the original quality exactly. When stream copy is not possible, it falls back to fast H.264 re-encoding.

Set your cut range using the visual timeline — drag the green start handle and red end handle to define exactly the portion you want to keep. Fine-tune with the precise timestamp inputs for millisecond accuracy. Once satisfied with the selection, click "Cut Video Now" and download the trimmed clip instantly as an MP4 file.

Frequently Asked Questions

How do I trim an MP4 video online?

Upload your MP4 file, drag the timeline handles (or type start/end times), then click "Cut Video". The trimmed MP4 downloads directly to your device — no account or installation needed.

Does cutting the video reduce quality?

No. We use stream copy technology whenever the container allows it, which extracts your clip without re-encoding — preserving 100% of the original quality.

Is there a watermark on the output?

Never. The downloaded file is a clean cut of your original video with no watermarks, logos, or branding added.

Is this video cutter really free?

Yes — completely free, with no account required and no usage limits. The processing runs in your browser using open-source FFmpeg WebAssembly.

Can I cut large video files (over 500 MB)?

Which video formats are supported?

The tool supports MP4, MOV, and WebM. Most videos recorded on phones or exported from editing software will work directly.

Is my video uploaded to a server?

No. Your file never leaves your device. All cutting happens client-side using FFmpeg compiled to WebAssembly — no uploads, no cloud storage, no privacy risk.
