Does conversion use a server?

No. FFmpeg runs inside the tab. Your files are not sent to QVI.

Can I convert many files at once?

Yes. Add multiple files to the queue. They share one output format and quality, then you can download each file or a ZIP of successful outputs.

Will converting to WAV improve quality?

WAV is uncompressed. It will not add detail missing from a lossy source, but editors often prefer it. Lossy-to-lossy (for example MP3 to M4A) may change size and character.

Which formats are supported?

Inputs include MP3, WAV, M4A, AAC, OGG, FLAC, and Opus. Outputs are MP3, WAV, M4A, OGG, and FLAC with unified Hz, channels, and bitrate options.

How do I convert audio formats?

Drop one or more audio files (MP3, WAV, M4A, AAC, OGG, FLAC, Opus).
Choose the output format and shared quality settings.
Tap Convert all, preview each result, then download files or a ZIP.

Output format, sample rate, channels, and bitrate apply to every file in the queue. Changing them clears previous results so the batch stays consistent.
