We use both open source and custom software to make sure our conversions are of the highest quality. In most cases, you can fine-tune conversion parameters using “Advanced Settings” (optional, look for the icon).

Free & Secure

Our OPUS to iPhone Audio Converter is free and works on any web browser. We guarantee file security and privacy. Files are protected with 256-bit SSL encryption and automatically deleted after 8 hours.


Opus is an open, royalty-free lossy audio codec standardised by the IETF as RFC 6716. It was designed to cover everything from low-bitrate speech to full-quality stereo music in a single codec, and it consistently outperforms MP3 and AAC at the same bitrate. Opus powers voice and audio in WhatsApp, Discord, Zoom, YouTube, and every WebRTC browser call, which makes it one of the most widely used audio codecs in the world.

 

How to open an Opus file?

Every major web browser plays Opus natively, so dragging the file into a browser tab works. On the desktop, VLC media player and foobar2000 both support it out of the box.

 

Android plays Opus natively, and FFmpeg handles conversion from the command line. Some older hardware players, car stereos, and editing programs still do not recognise the format — in that case convert it with our Opus to MP3 tool. You can also convert the file with our OPUS to MP3 tool.

iPhone Audio is an M4A file encoded for Apple iPhone, containing AAC audio in an MPEG-4 container. AAC delivers noticeably better sound than MP3 at the same bitrate, which is why Apple adopted it as the default for the iTunes Store and for music on iOS. Choosing this preset produces a file the iPhone plays natively, with artwork and track tags intact.

 

How to open an iPhone Audio file?

On the phone, the file plays straight away in the Music, Voice Memos, or Files app — nothing extra is required.

 

To get the file onto the device, sync it through iTunes, the Finder on macOS, or iCloud Drive. On a computer the same M4A opens in iTunes, the Apple Music app, Windows Media Player, VLC media player, and every major web browser. For maximum compatibility with older devices, convert it with our M4A to MP3 tool.
