How to Convert MP4 to OGG Online

Upload your MP4 file

Drag and drop your .mp4 file onto the page or click to browse. You can select several MP4 files at once to batch-convert them.

OGG is preselected

The output format is already set to OGG, so you can convert immediately. If you need to, adjust the audio codec, bitrate or sample rate in the settings panel first.

Convert and download

Click Convert. The OGG file is processed on your own device; nothing is uploaded to a server. When it finishes, click Download to save it (or Download all to get a batch as a ZIP).

Why Convert MP4 to OGG?

OGG with Vorbis or Opus audio is patent-free and natively supported by Firefox, Chrome, Android and most game engines including Unity and Godot. Converting MP4 to OGG is the standard way to prepare background music or sound effects from a video for a game or website.

Our converter lets you pick Vorbis for maximum compatibility or Opus for the best quality at low bitrates. Either way the conversion runs locally in your browser, so even long gameplay recordings convert without an upload.

Private by design: your MP4 file is converted on your own device and never uploaded.
OGG preselected: the output format is already chosen, so it is a one-click conversion.
Batch friendly: convert several MP4 files in one go and download them as a ZIP.
No limits, no watermark: free for files of any size, with nothing stamped on the output.

MP4 vs OGG

MP4 (MPEG-4 Part 14): MP4 is the most widely supported video container in the world. It usually carries H.264 or H.265 video with AAC audio, plays on every phone, browser, TV and editing app, and is the safest choice for sharing. It is best for sharing, social media, web playback and mobile devices.

OGG (Ogg Vorbis / Opus): OGG is the open Xiph.org container, usually carrying Vorbis or Opus audio. It is patent-free and common in games, open-source software and web audio. It is best for games, web audio and open-source tools.

In short: keep MP4 when the priority is sharing, social media, web playback and mobile devices, and switch to OGG when the file is headed for games, web audio and open-source tools. Need a different target? The full Video Converter supports every format listed below.

MP4 to OGG FAQ

Should I choose Vorbis or Opus inside OGG?

Opus sounds better at every bitrate and is ideal for voice, but a few older players and engines only understand Vorbis. If you are unsure, Vorbis at 160 kbps is the safe choice.

Do web browsers play OGG audio?

Chrome, Firefox, Edge and Android all play OGG natively. Safari and iOS have limited support, so offer an M4A or MP3 fallback on Apple-heavy sites.

Is this MP4 to OGG converter free?

Yes. Converting MP4 to OGG on MediaConverter.io is completely free, with no watermark, no sign-up and no daily conversion limit.

Are my MP4 files uploaded to a server?

No. The converter runs inside your browser using WebAssembly and WebCodecs, so your .mp4 file is read and converted on your own device. Nothing is uploaded, which keeps private recordings private and means there is no waiting in an upload queue.

Is there a file size limit for MP4 to OGG?

No fixed limit. Because processing happens locally, the practical limit is your computer's memory and patience; multi-gigabyte MP4 files convert fine on a desktop browser. Very large files take longer on phones.

Will converting MP4 to OGG reduce quality?

OGG is a lossy format, so the MP4 audio is decoded and re-encoded. Keep the bitrate at 100% (or pick 256 to 320 kbps) and the difference is inaudible for almost all listeners.

Which browsers support the MP4 to OGG converter?

Current versions of Chrome, Edge, Firefox and Safari on desktop all work. Chrome and Edge are fastest because they expose hardware-accelerated WebCodecs decoders.
