Common Audio Conversion Scenarios
Music Library Conversion
Convert your entire music collection between formats. Moving from Apple to Android? Convert M4A to MP3. Archiving your CD collection? Convert WAV to FLAC for lossless storage at half the size.
Voice Message Conversion
WhatsApp and Telegram save voice messages as OPUS files that many devices can't play. Convert them to MP3 for universal playback, archiving, or use in presentations and video projects.

Frequently Asked Questions
What audio formats can I convert between?
XConvert supports 19 input formats including MP3, WAV, FLAC, AAC, OGG, OPUS, M4A, WMA, AIFF, AC3, AMR, AU, DSS, M4B, OGA, VOC, and WEBA. Output to all major formats including MP3, WAV, FLAC, AAC, OGG, OPUS, M4A, WMA, and AIFF.
Does converting audio lose quality?
It depends on the formats. Converting between lossless formats (WAV ↔ FLAC ↔ AIFF) preserves perfect quality. Converting from lossless to lossy (FLAC → MP3) discards some data but is imperceptible at high bitrates. Converting between lossy formats (OGG → MP3) introduces a small generation loss.
What's the best format for music?
For everyday listening: MP3 at 256-320kbps (universal compatibility). For archival: FLAC (lossless, half the size of WAV). For Apple devices: AAC/M4A at 256kbps. For audiophile listening: FLAC or WAV.
Can I extract audio from video files?
XConvert has dedicated tools for extracting audio from video — see our MP4 to MP3, MOV to MP3, and WebM to MP3 converters.
Can I convert multiple files at once?
Yes. Upload multiple audio files and convert them all to the same output format with the same quality settings. Download individually or as a ZIP archive.
Can I adjust the audio quality and bitrate?
Yes. Advanced Options let you set the output bitrate (64-320kbps for lossy formats), sample rate (8kHz-48kHz), and channel configuration (mono/stereo).
