Turn a QuickTime MOV (from your iPhone or Mac) into an MP4 that plays everywhere — in seconds, in your browser.
MOV is what your iPhone, iPad, or QuickTime Pro records by default. It plays perfectly on Apple devices but is awkward everywhere else: Windows Media Player often refuses it, Discord and older editing tools trip over its structure, and upload-to-web flows frequently ask for MP4 instead. Converting to MP4 fixes all of that in one go.
The good news: MOV and MP4 share the exact same underlying container (ISO-BMFF), so most of the time this is a pure remux — we re-wrap the video and audio tracks into an MP4 shell without re-encoding them. That means zero quality loss and conversions measured in seconds rather than minutes, even for hour-long clips. Everything runs locally in your browser.
MOV is Apple's QuickTime container and shares the same ISO-BMFF structure as MP4 — which is why converting between them is usually a fast remux rather than a re-encode.
MP4 is the most widely supported video container. Output here is mastered with fast-start so it plays instantly in web and mobile players.
