Video Editor

About the Video Editor

A live-preview video editor: every change to framing, colour, fades and text shows instantly on the preview canvas while you scrub a visual timeline with in/out handles, frame stepping and loop playback. Crop to 16:9, 9:16, 1:1 or 4:3, mix in background music or replace the soundtrack, then use fast in-browser export or the high-quality FFmpeg WebAssembly export. Powered by FFmpeg compiled to WebAssembly, running entirely on your device. Load any MP4, WebM, MOV or MKV and trim by start/end time, crop or resize, rotate or flip, change playback speed, adjust volume or mute, add fade-in/fade-out, tune brightness, contrast and saturation or go black & white, and burn a text watermark into any corner. Export as MP4 (H.264), WebM or animated GIF with CRF quality and frame-rate controls, watch progress live, inspect the exact FFmpeg command, and download the result. Your video is never uploaded to a server.
