MP4 tips

🍏

iOS Safari cannot play WebM natively. Converting to MP4 (H.264) is the reliable fix for sending video to iPhone and iPad users.

🎬

MP4 with H.264 is the single most compatible video format — it plays on virtually every device, browser, and editor.

⚡

The converter re-encodes locally on your CPU. HD clips take a little time; the engine pre-loads while you choose your format.

🔒

Your video never uploads — useful for screen recordings and private clips you don't want on a conversion server.

Bestand kiezen

Drop your file into the tool above. It stays entirely on your device — nothing is sent to any server.

The tool processes your data instantly in your browser using JavaScript. No server, no waiting.
