Frequently Asked Questions

This tool supports all common audio formats including MP3, WAV, OGG, FLAC, AAC (M4A), and more. You can mix different formats—they'll be converted to a common format during merging.

The output is encoded at high quality (320kbps for MP3, quality 7 for OGG, or lossless for WAV/FLAC). Starting from high-quality sources yields the best results. Mixing formats requires transcoding which may affect quality slightly.

You can merge as many files as your browser can handle. Processing happens locally, so limits depend on your device's memory. Merging 10-20 typical audio files works well on most devices.

Choose MP3 for maximum compatibility with all devices. Use OGG for games and web apps. WAV or FLAC for lossless quality. AAC (M4A) for Apple devices and podcasts.

Processing time depends on total audio duration and your device. Merging a few songs typically takes 10-30 seconds. Longer compilations may take a minute or more.

Metadata from individual files is not preserved in the merged output. The merged file will have default metadata. Use a separate metadata editor if needed.
