Video Trimmer

When to use Video Trimmer

You just finished a two-hour Zoom recording of a product demo, and the actual demo starts at 12:34 and ends at 47:10 — everything else is small talk. Drag the file in here, set the start and end times with the sliders, and download just the part that matters. ffmpeg.wasm runs a full FFmpeg build via WebAssembly on your computer, using stream copy mode so the cut happens at the nearest keyframe without re-encoding — zero quality loss and no waiting for a long transcode. Handles files up to 500 MB. The trimmed file downloads directly to your device, ready to send to a client, upload to Loom, or hand off to an editor.

• Cut a 2-hour Zoom recording down to the 35-minute demo segment for a client
• Cut dead air off a screen capture before sharing it in Loom
• Chop out a blooper from a tutorial video before uploading it to YouTube

About this tool

A clean cut at exactly the right frame, without re-encoding or waiting for an upload to finish. Drag in your video, set precise start and end times with the sliders, and download the trimmed version — lossless, instant. Handles files up to 500 MB. Good for cutting the dead air off a screen recording before you send it, trimming a clip for a presentation, or chopping out the part you don't need before compressing. Runs in your browser, not ours — your video never touches a remote server.
