Frequently Asked Questions
How does the online video trimmer work?
Drop your video into the browser, set the start and end times using the slider or number inputs, preview the trimmed portion, then click export. The video is processed entirely on your device using ffmpeg.wasm — nothing is uploaded to any server.
Is this video trimmer free to use?
Yes, completely free with no watermarks, no sign-up, and no hidden limits. You can trim as many videos as you want.
What video formats can I trim?
You can trim any video format your browser supports, including MP4, WebM, MOV, and AVI. The exported file is always a standard MP4 (H.264 + AAC) compatible with all devices and platforms.
Is my video uploaded to a server?
No. Your video never leaves your device. All processing happens locally in your browser using WebAssembly, so your files stay completely private.
How long does exporting take?
Export time depends on the clip length and your device speed. The video is re-encoded to MP4 in your browser. Short clips (under 30 seconds) typically export in a few minutes on modern devices.
Is there a maximum video length or file size?
The tool accepts files up to 500 MB. There is no hard limit on video duration, but very long videos will use more memory and take longer to process since everything runs in-browser.
