❓ FAQ
What video formats are supported?▼
All major browser-compatible formats: MP4, WebM, OGG, AVI, MOV. Output is WebM (VP8/VP9) — natively supported by all modern browsers with excellent quality.
Is my video uploaded to a server?▼
No. Processing happens entirely in your browser. Your video is never uploaded anywhere. Data is released from memory immediately after processing. Safe for sensitive content.
How do I use this video trimmer?▼
1) Upload a video file; 2) Use sliders or 'Mark Start/End' buttons to select the segment; 3) Click 'Trim Video' — it processes locally and downloads automatically when done.
Will the trimmed video quality be good?▼
Yes. The trimmed clip keeps original frame rate and resolution. WebM VP8/VP9 encoding delivers excellent quality. Output quality depends on your browser's encoder capabilities.
Are there size or duration limits?▼
No hard limits, but we recommend under 30 minutes or 2GB for smooth performance. Long videos can be processed in segments. Keep the browser tab active during processing.
