    How to edit a video in your browser

    1. Import your clips — click Import or drop MP4, WebM or MOV files onto the library.
    2. Build the timeline — press + on a library clip or drag it onto the timeline. Drop files directly on the timeline to import and append in one step.
    3. Trim — drag the ◀ ▶ edges of any clip to cut the start or end. Double-click a trimmed clip to reset it.
    4. Preview — press Play. The timeline plays as one continuous video, so what you see is what you export.
    5. Export — pick a frame rate, keep audio on, and download a WebM rendered from every single frame.

    What this simple editor does

    Join clips into one video

    String multiple clips together in any order. Remove a clip and re-add it elsewhere to rearrange — the preview always plays the full timeline start to finish.

    Non-destructive trimming

    Trimming never touches your original files — it only narrows the window each timeline clip plays. Clip widths, totals and the export all update live while you drag.

    Frame-accurate WebM export

    The exporter seeks through every frame at your chosen frame rate and encodes them with your original audio, so motion matches the preview exactly with zero dropped frames.

    Video editor FAQ

    Is this video editor free?

    Yes — free with no account. Your device does all the work, so there are no server costs, no trial clock and no watermark added to your export.

    Are my videos uploaded anywhere?

    No. Importing, previewing, trimming and exporting all happen locally in your browser tab. Closing the tab removes every trace.

    What formats can I import and export?

    Import MP4, WebM, MOV and common audio files (H.264, VP8 and VP9 decode best). Export is WebM at source resolution with audio preserved — playable on YouTube, Drive and TikTok.

    Will trimming delete parts of my original video?

    Never. Trims only change which slice of each clip the timeline plays. Double-click any trimmed clip to restore the full length instantly.

    Which browser works best?

    Chrome or Edge, which support the WebCodecs API behind the frame-accurate export. Keep the tab focused while rendering so background throttling can't slow it down.
