Are my video files uploaded to a server?
No. The Video Trimmer runs 100% locally in your browser using WebAssembly. Your files are never uploaded to any server, ensuring total privacy.
What video formats do you support?
We support common video formats including MP4, WebM, and MOV, relying on your browser's native capabilities and FFmpeg.
Is the video quality degraded when trimming?
No, if you export in the same format, we use FFmpeg to accurately extract the video segment without re-encoding the original data, maintaining the highest quality.
How does the timeline scrubber work?
Our trimmer provides a visual timeline with draggable start and end handles. Simply drag them to set your desired video segment.
Can I edit very large video files?
Yes, but since processing happens in the browser, very large files (e.g., over 500MB) may take longer to export depending on your device's RAM and CPU.
Is this tool free to use?
Absolutely. Our Video Trimmer is entirely free to use with no hidden fees, subscriptions, or watermarks.
Does it process quickly?
Yes, by utilizing WebAssembly and optimized FFmpeg commands (like placing -ss before the input), we ensure the fastest possible local extraction.
Can I watch just the selected part?
Yes, clicking the Play button while you have a selection active will loop playback strictly within your chosen start and end points.
Do I need to install any software?
No installation is required. The tool operates completely within your modern web browser using standard web technologies.
Can I use this on my mobile device?
Yes, the tool is responsive. However, video processing on mobile devices may be slower than on a desktop computer due to hardware limitations.
What happens if I accidentally refresh the page?
Since all processing is done locally without accounts, refreshing will reset your session and you will need to load your file again.
Why does the export take a few seconds?
Exporting utilizes FFmpeg running inside your browser via WebAssembly to guarantee a valid output file. This ensures accurate trimming.
Can I trim multiple parts at once?
Currently, our tool supports trimming a single, continuous segment per export. You can repeat the process for multiple cuts.
Is there a file size limit?
Since everything runs in your browser, the limit depends on your device's available RAM. Files up to a few hundred megabytes are recommended.
Can I extract audio only?
For audio extraction or trimming, please use our dedicated Audio Trimmer tool.
