About Video Trimmer
Last updated: May 2026
OptiPix Video Trimmer lets you cut and trim video files directly in your browser. Upload MP4, WebM, MOV, AVI, or MKV files, set precise start and end times, and export the trimmed clip. Supports keep-selection and remove-selection modes. Uses FFmpeg.wasm for processing - copy mode for fast trimming without re-encoding, or re-encode for frame-accurate cuts. Your videos never leave your device.
How It Works
FFmpeg.wasm trims the video using -ss (start) and -to (end) flags. Copy mode (-c copy) is fast but key-frame dependent. Re-encode mode gives frame-accurate cuts.
Use Cases
- •Trim video for social media
- •Cut intro/outro from recordings
- •Extract clips from long videos
- •Trim screen recordings
- •Cut video for email attachment
