Convert video to MP4 without uploading it
Most online converters upload your video to their servers first, which is slow and leaks your file. This converter runs entirely in your browser using WebAssembly, so your clip never leaves your device. Pick a video in almost any format — MOV, MKV, AVI, WebM — and we re-encode it to a clean, widely-compatible MP4 (or MOV/MKV) you can save instantly.
How to convert a video
Click Choose a video and select a file from your device. Pick your target format (MP4 works everywhere), then press Convert — the tool loads a small video engine the first time, then converts everything locally and shows a preview. When it's ready, download it. No account, no upload, no watermark.
Private by design
Because the conversion happens on your device, your video is never sent anywhere and nothing is stored. It works on desktop and modern mobile browsers — the first conversion downloads the engine once, then later conversions are instant.
