FFmpeg-Powered Server Conversion

Every conversion runs through FFmpeg on dedicated servers. The OGG Vorbis stream is fully decoded to PCM, then re-encoded to AAC at a high bitrate to keep the quality penalty of transcoding between two lossy formats as low as possible.

Deep Dive

OGG vs AAC: Open Source vs Apple Ecosystem

OGG Vorbis is an excellent open-source codec but is blocked by iOS and ignored by most consumer electronics. AAC trades the open-source advantage for near-universal device and platform support.

Apple devices and ecosystems that support AAC audio natively

OGG Vorbis: Open, Efficient, Ecosystem-Limited

OGG is a container format developed by the Xiph.Org Foundation. It typically carries Vorbis-encoded audio, which is a patent-free, open-source lossy codec that competes well with AAC and MP3 on quality per bit. OGG Vorbis is the default format for many Linux desktop environments, game engines, and open-source software.

TypeLossy compression (Vorbis codec)

Container.ogg

iOS supportNot supported natively

OGG Vorbis is not recognized by iOS, iPadOS, or Safari without a third-party app or web polyfill.

AAC: The Standard for Apple and Streaming

AAC (Advanced Audio Coding) is the default audio codec for all Apple platforms and services. It is used by iTunes, Apple Music, FaceTime, YouTube, Spotify, and most major streaming services. AAC delivers excellent quality at low bitrates and is natively decoded in hardware on iOS, macOS, and most Android devices.

TypeLossy compression

Typical bitrate128 to 256 kbps

Container.aac or .m4a

AAC is hardware-decoded on iPhone, iPad, and Mac, which means lower battery drain compared to software-decoded codecs.

Transcoding: Quality Impact of OGG to AAC

Converting from OGG to AAC involves decoding the Vorbis stream and re-encoding as AAC. Since both are lossy formats, there is a small additional quality penalty. Using a high AAC output bitrate reduces this to a level that is inaudible to most listeners under normal listening conditions.

Quality impactMinor at high output bitrates

Recommended output192 kbps or 256 kbps for best results

If lossless output is needed instead of compatibility, convert to FLAC or WAV rather than AAC.

When AAC Is the Right Choice

AAC is the right choice whenever the destination is an Apple device, an iOS app, an Apple Music or Podcast submission, or any streaming platform that processes incoming audio through its own AAC encoder. It is also the best choice for game and app developers targeting iOS.

Best foriPhone, iPad, Mac, Apple Music, YouTube, Spotify, iOS apps, streaming

Supported byAll Apple devices, Android, Windows, most media players

Output is packaged in an M4A container (.m4a extension), which is the standard AAC delivery format for Apple devices.

Who Uses It

Who Converts OGG to AAC

Game developers, Apple device users, music distributors, and cross-platform teams all need OGG content in a format the Apple ecosystem accepts.

Game developers, Apple users, and music creators converting OGG to AAC

Game Developers Targeting iOS

Game engines like Unity and Godot use OGG as a default audio format for cross-platform builds. iOS does not support OGG natively, so audio assets must be re-packaged as AAC (M4A) for any iOS or App Store build.

Compatible withUnity (iOS build), Godot (iOS export), Unreal Engine

Users Moving from Android to iPhone

Music apps and game audio on Android often use OGG files. Converting your library to AAC before moving to an iPhone means every track plays in the native Music app without installing anything extra.

Music Producers Distributing on Apple Music

Apple Music distribution through platforms like DistroKid, TuneCore, or CD Baby processes uploaded audio as AAC. Submitting an AAC source file avoids a lossy-to-lossy transcoding step in the distribution pipeline.

Podcast Producers Targeting Apple Podcasts

Apple Podcasts recommends AAC as the preferred audio codec. Converting OGG recordings to AAC before submission ensures the feed validates correctly and audio plays natively in the Podcasts app.

Apple recommendationAAC at 128 kbps mono or 192 kbps stereo

Linux and Open-Source Users Sharing with Apple Users

Linux desktops and open-source media tools produce OGG by default. Converting to AAC before sharing with colleagues or clients on Mac or iPhone removes the need for them to install a third-party player.

Web Developers and Front-End Engineers

Safari on iOS does not support OGG in the HTML5 audio element. Converting background music, sound effects, or voice-over assets to AAC ensures they play across all browsers, including Safari on iPhone and iPad.

Browser supportSafari, Chrome, Firefox, Edge all support AAC/M4A

Frequently Asked Questions

Why does iOS not support OGG files?

Apple chose not to include a Vorbis decoder in iOS or macOS because OGG Vorbis is not part of the MPEG or ISO standard codec families that Apple supports natively. AAC, which is an ISO standard codec, is fully hardware-decoded on all Apple devices.

Will I lose quality when converting OGG to AAC?

Yes, a small amount of quality is lost because both OGG Vorbis and AAC are lossy formats. Converting between them requires decoding the OGG and re-encoding as AAC, which introduces a second round of compression. Using a high output bitrate keeps this penalty minimal and inaudible to most listeners.

What file extension does the converted AAC file use?

The output uses the .m4a extension, which is the standard MPEG-4 container for AAC audio. All Apple devices, Android, and most modern media players recognize it natively.

Can I use the converted AAC file in an iOS game or app?

Yes. iOS natively decodes AAC audio in hardware. Unity, Godot, and other game engines automatically use the AAC asset on iOS builds. Rename the .m4a to .aac if your engine requires that extension.

Does Safari support AAC audio on iPhone?

Yes. Safari on iOS and macOS supports AAC (M4A) natively in the HTML5 audio element and Web Audio API. This makes AAC the correct format for any web audio that must work across all browsers including Safari.

Is there a file size limit?

The upload limit is 100 MB per file. Most OGG tracks and game audio assets are well within this limit.
