Frequently asked questions

How do I trim a video online?
Upload a video file, preview it in the browser, enter the start and end times in seconds, then click Trim video. When trimming finishes, download each clip individually or export all clips as a ZIP.
Is this video trimmer free?
Yes. This video trimmer is completely free with no account, card, or software install required.
Are my video files uploaded to a server?
No. Trimming runs locally in your browser using FFmpeg compiled to WebAssembly. Your video files are not uploaded to Vidsembly or any third-party server.
What video formats can I trim?
Common formats including MP4, WebM, MOV, AVI, MKV, M4V, WMV, and other video files are supported. Browser playback and export support can vary by codec, so MP4 and WebM usually work best.
Can I trim multiple videos at once?
Yes. Add multiple video files, set a start and end time for each one, then trim them in one session. Download clips individually or use Download All to export a ZIP.
Will trimming change my video quality?
The trimmer keeps the original video and audio streams when possible, so clips export quickly without intentional quality loss. Some formats may trim near the closest safe cut point depending on the source video.
Does the video trimmer download in the same format as the upload?
Yes. Trimmed clips keep the same file extension as the source video, such as MP4 in and MP4 out. The tool uses stream copy when possible, so video and audio are not re-encoded into a new format. Downloads use your original filename with -trimmed before the extension.

About this tool

Trim video without uploading files

This free video trimmer runs in your browser, so your footage does not need to leave your device just to cut a shorter clip. It is useful for lecture recordings, social snippets, meeting recaps, training videos, and draft creator content.

Set precise start and end times

Preview each uploaded video, note the moment where the clip should begin and end, then enter those times in seconds. The tool queues each file separately, so you can cut different segments from different videos in one workspace.

When to trim video before sharing

Trim video before posting a highlight, sending a client review clip, uploading a lesson excerpt, or removing dead time from a screen recording. Shorter clips are easier to review, upload, and reuse across channels.

Best formats for browser video trimming

MP4 and WebM files generally work best in modern browsers. MOV, AVI, MKV, M4V, WMV, FLV, OGV, MPEG, MPG, and 3GP files are also accepted, although playback and export behavior depends on the codecs inside the file.

Batch trimming and ZIP export

You can add several videos, set unique clip ranges, trim them in sequence, and export results individually or as a ZIP. That helps when preparing classroom clips, customer call snippets, social posts, or internal training segments in one pass.
