How do I convert ALAC files to OPUS?

Select your ALAC files, set output to OPUS, choose a bitrate (96-160 kbps is typical), and click Convert. The tool will re-encode each file and let you download the result immediately.

Why should I convert ALAC to OPUS?

ALAC is a lossless codec that creates large files, often 20-30 MB per minute of audio. OPUS is a lossy codec that delivers perceptually transparent sound at 96-128 kbps, cutting file size by 50-70%. This makes OPUS ideal for mobile devices, cloud libraries, and bandwidth-limited streaming.

What happens to audio quality and metadata when converting ALAC to OPUS?

During conversion, the audio is decoded and re-encoded using Opus. Bit depth is effectively quantized to lossy precision, but at bitrates above 128 kbps it's transparent to human hearing. Sample rate is resampled to 48 kHz. Mono, stereo, and multichannel layouts are preserved, and ID3/metadata tags such as title, artist, and cover art are carried over. Note that the output is not bit-perfect due to lossy compression.
