How do I convert an IFF audio file to OPUS?

Click 'Upload' to select your IFF file, then choose OPUS as the output format. Optionally adjust bitrate—we recommend 128 kbps for good quality and compact size. Click 'Convert' and download your new OPUS file. No software installation is required; the conversion is done entirely in your browser.

Why should I convert IFF to OPUS instead of keeping the original?

IFF is an uncompressed audio format, which results in large files. OPUS is a modern lossy codec that compresses audio to roughly 10% of its original size while preserving near-transparent listening quality. OPUS is also natively supported in all major web browsers, making it the ideal format for streaming, online playback, and efficient storage.

What happens to the audio quality and metadata when converting IFF to OPUS?

The IFF file is decoded to raw PCM and then re-encoded to OPUS at the bitrate you select (64-512 kbps). Sample rate and channel count are preserved, but the lossy process discards some perceptually redundant audio data. At higher bitrates, the result is nearly indistinguishable from the original; lower bitrates reduce file size further at the cost of potential artifacts. Metadata like title and artist is not carried over—you may need to add tags after conversion.
