MP4 to OGG Converter
OGG is the open audio format that game engines, Minecraft resource packs and Linux software reach for first. This page extracts the sound of an MP4 and saves it as Ogg Vorbis, with Opus one click away for voice messages.

Max 95 MB per file· Up to 20 files· Deleted after 30 minutes
Files are processed on our servers and deleted after 30 minutes.
Keep the source rate unless a device or app asks for one. 44.1 kHz is CD standard, 16 kHz is enough for speech recognition.
Mono halves the size of lossless files and is fine for speech.
16-bit is CD quality. Choose 24-bit only if you will edit or master the audio.
Videos with several languages or a commentary have more than one track. 1 is the main track.
Optional. Seconds (e.g. 75) or minutes:seconds (1:15). Leave empty to start at the beginning.
Optional. Same format as the start time. Leave empty to keep everything up to the end.
How to use this tool
- 1
Upload your MP4 videos
Choose up to 20 MP4 files of up to 95 MB each. Other video files such as MOV or MKV are accepted as well.
- 2
Confirm OGG and the bitrate
Convert to is set to OGG at 160 kbps. Switch to Opus for a voice message, or lower Bitrate to 96 kbps for background sounds in a game.
- 3
Extract to OGG
Press Extract to OGG. Each video becomes an .ogg file with the same name, ready to drop into your project folder.
Upload the MP4, leave Convert to on OGG, press Extract to OGG: the sound becomes a 160 kbps Ogg Vorbis file and the video is dropped.
OGG, Vorbis and Opus: what the .ogg file contains
Ogg is a container developed by the Xiph.Org Foundation, and Vorbis is the audio codec that made it famous; Vorbis 1.0 was released in 2002 as a patent-free answer to MP3. When people say "an OGG file" they almost always mean Ogg Vorbis, and that is what the OGG choice on this page produces.
Opus, standardized by the IETF as RFC 6716 in 2012, is the newer codec from the same circle. It usually lives in the same Ogg container but with an .opus extension, and it beats Vorbis on speech and at low bitrates. That is why chat apps use it for voice notes, while game tools and resource packs still ask for Vorbis by name.
Converting from an MP4 means decoding its AAC track and encoding again, so pick the codec for where the file goes, not for the best spec sheet. The comparison below sums it up.
Ogg Vorbis
The default on this page.
- Named in Minecraft and Godot docs
- Good music quality at 128–192 kbps
- No licensing fees
Ogg Opus
Pick Opus in Convert to.
- Clear speech at 32–64 kbps
- Format of Discord and Telegram voice messages
- Always decoded at 48 kHz
MP3
The fallback when OGG is refused.
- Plays on every device and car stereo
- Needs a higher bitrate for the same quality
- Patents expired in 2017
Where an OGG file is required or preferred
| Organisation | Requirement | Source |
|---|---|---|
| Minecraft Java Edition resource packs | Custom sounds must be Ogg Vorbis files with the .ogg extension. | — |
| Godot Engine | The import docs suggest Ogg Vorbis for music and long ambience, WAV for short effects. | — |
| Telegram Bot API (sendVoice) | Shows a file as a voice message when it is an .ogg encoded with Opus; pick Opus here. | — |
| Discord voice messages | Recorded and stored as Ogg Opus; ordinary uploads of any format play as attachments instead. | — |
MP4
MPEG-4 video
MP4 (MPEG-4 Part 14) is a multimedia container standardised by ISO/MPEG and based on Apple's QuickTime format. It usually holds H.264 or HEVC video with AAC audio, and can also carry subtitles, chapters and metadata. It is the most compatible video format in the world, playing on phones, browsers, TVs, game consoles and social platforms. The video inside is almost always lossy, so repeated re-encoding gradually reduces quality.

OGG
Ogg Vorbis audio
OGG files use the Ogg container from the Xiph.Org Foundation, most often with the lossy Vorbis codec and sometimes Opus or FLAC. Vorbis is open and royalty-free and sounds comparable to or better than MP3 at similar bitrates. It is widely used for game audio, open-source software and some streaming services. Older iPhones, some car stereos and many editors do not support OGG.

People convert MP4 to OGG to get a video's soundtrack into a game engine, a Minecraft resource pack or open-source software that expects royalty-free Ogg Vorbis rather than AAC or MP3.
MP4 to OGG questions
Is OGG the same as OGV?
They share the Ogg container but not the content. An .ogv file is video, usually Theora picture with Vorbis sound, while .ogg normally holds audio only. This page makes audio; to keep the picture, use the video converter.
Should I pick OGG or Opus for a Discord or Telegram voice message?
Opus. Both apps record voice messages as Opus inside an Ogg container, and Opus is designed for speech at low bitrates. Choose Opus in Convert to and 64 kbps mono; plain OGG here means Vorbis, which those apps treat as an ordinary audio attachment.
Will an OGG file play on an iPhone?
Not reliably. Apple added Ogg support late and only partly, so older iPhones and some apps still reject it. If the audio is meant for Apple devices, MP4 to M4A keeps the AAC family that iOS handles everywhere.
Which OGG bitrate do I need for game music?
Around 160 kbps sounds clean for music, and Spotify long used Ogg Vorbis at 96, 160 and 320 kbps for its quality tiers. Short sound effects can go down to 96 kbps; a looping ambience track is usually fine at 128 kbps.
Does converting MP4 to OGG lose quality?
Slightly. The AAC sound in the MP4 is decoded and re-encoded as Vorbis, a second lossy step. At 160 kbps or above the difference is hard to hear; avoid converting the result again.
Can Unity use the OGG files from this page?
Yes. Unity imports .ogg along with WAV, MP3 and AIFF and then recompresses audio to its own setting on build, so a 160 kbps Vorbis file is a good source for it.
