Flippy turns OGG into MP4 for free: upload the OGG above and download it wrapped as MP4, sound untouched. No signup, and both files delete themselves within an hour.

It sounds backwards, but OGG to MP4 is a real need: plenty of platforms and tools only accept video, so Flippy re-packs your OGG audio inside an MP4 wrapper. Where MP4 accepts your OGG's codec the sound crosses over untouched; where it doesn't, it's re-encoded once. The MP4 that comes out is built for playing everywhere: browsers, phones, TVs, editors, slide decks.

A classic OGG to MP4 job: game audio banks and open-source project files, bound for feeds, chats and slide decks that expect video.

Why flip OGG to MP4

OGG is the free spirit of audio: open, patent-free, and quietly brilliant at looping game sound. It was born in 2002, the Xiph.Org Foundation, and its real weak spot is everyday device support: car stereos and Apple hardware mostly shrug.

MP4 is the world's default video: the file that plays before anyone has to think about it. A container, most often carrying H.264 or H.265 video with AAC audio. That makes it the right destination when what you need is playing everywhere: browsers, phones, TVs, editors, slide decks.

Drop your OGG file into the flipper above, or click to browse for it.

Best settings for OGG to MP4

Settings for OGG to MP4: none to pick. Where the MP4 container accepts your OGG's audio codec, the stream is copied bit for bit; where it doesn't, Flippy re-encodes it once and leaves the levels alone.

OGG vs MP4, side by side

	OGG	MP4
Born	2002, the Xiph.Org Foundation	2001, the MPEG standards group, built on Apple's QuickTime design
Type	audio · lossy	video · container
Best for	games and open projects that want seamless loops and zero licensing strings	playing everywhere: browsers, phones, TVs, editors, slide decks
Weak spot	everyday device support: car stereos and Apple hardware mostly shrug	very little day to day: as a container its quality depends on the codec inside
Typical size	on par with MP3, often a touch smaller at matching quality	for video content, roughly 50–100 MB per minute at 1080p, depending on bitrate; wrapping audio alone stays about the size of the OGG
Plays on	Browsers, Android, game engines; not the Apple ecosystem.	Every browser, phone, TV and editing app worth mentioning.

Questions people ask

Will converting OGG to MP4 lose quality?

No. Wrapping audio in an MP4 container doesn't touch the sound itself: it's the same stream in a different box.

Will the MP4 file be bigger or smaller than my OGG?

About the same, plus a sliver of container overhead. The audio stream is unchanged; MP4 just adds a video-shaped envelope.

Where will the MP4 file play?

Every browser, phone, TV and editing app worth mentioning. That's the usual reason people leave OGG behind: MP4 simply opens in more of the places that matter.

How long does OGG to MP4 conversion take?

Seconds for most OGG files: there are no pictures to encode, so wrapping the audio as MP4 is nearly as fast as copying it. Both files auto-delete within an hour.
