Frequently Asked Questions
What video formats are supported?
This tool supports MP4 and WebM video files, which are the most common web-compatible formats. The trimmed output is saved as a WebM file using your browser's built-in MediaRecorder API.
Is my video uploaded to a server?
No. All processing happens entirely in your browser using the HTML5 Video element and MediaRecorder API. Your video never leaves your device, ensuring complete privacy.
How long does the trimming take?
The trimming process plays the selected portion in real-time while recording, so a 30-second clip takes approximately 30 seconds to process. Shorter clips are processed faster.
Why is the output in WebM format?
WebM is the format natively supported by the browser's MediaRecorder API, which allows client-side video encoding without any server processing. WebM files are widely compatible and offer good quality at smaller file sizes.
Is there a file size limit?
We recommend files under 500MB for the best experience. Since processing happens in your browser, very large files may be slow depending on your device's memory and processing power.
Can I trim videos on my phone?
Yes, this tool works on most modern mobile browsers that support the MediaRecorder API. Performance may vary depending on your device.
