About formats

AIFF

AIFF (Audio Interchange File Format) is an uncompressed audio container developed by Apple, based on the IFF structure. Like WAV it preserves full audio fidelity and is widely used in professional audio production on macOS, being the default format for Logic Pro and other DAWs.

Frequently Asked Questions

Is converting AIFF to OPUS free?
Yes. This AIFF → OPUS converter runs entirely in your browser and is completely free — no account, no credits, no watermark.
Which devices and platforms can I use to convert AIFF to OPUS?
Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.
Are my AIFF files uploaded to a server?
No. Files never leave your device. The entire AIFF → OPUS conversion runs locally in your browser, so your data stays private.
Can I convert multiple AIFF files at once?
Yes — batch conversion is supported. Add as many AIFF files as you like and convert them to OPUS in one pass, then download the results together.
What is the maximum file size?
There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.
Will converting AIFF to OPUS reduce the quality?
Because both formats use lossy compression, the OPUS output will not bring back any quality that has already been lost in your AIFF file. Avoid repeated re-encoding to keep the best quality.
Does OPUS support transparency?
No — OPUS has no alpha channel. Transparent areas of your AIFF file will be filled with a solid background colour in the converted file.
Will the converted OPUS file be smaller than the AIFF?
Usually yes. Converting from a lossless or uncompressed format to a lossy one dramatically reduces file size. Typical savings range from 50% to 90%, depending on the quality setting you choose.
