Online Audio Converter — 40+ Formats
Our service converts audio files between popular and professional formats. Supported lossy formats (MP3, AAC, OGG, WMA, OPUS), lossless formats (FLAC, WAV, AIFF, ALAC, APE), plus specialized formats for mobile devices, voice communication, and professional audio.
How It Works
Most popular formats (MP3, WAV, FLAC, OGG, AAC, M4A, AIFF, etc.) are processed right in your browser — files are not uploaded to server. This is fast and secure. For rare formats (WMA, ALAC, APE, AMR, OPUS, etc.) server processing is used with a limit of 1 file up to 30MB.
Features
- Batch conversion — up to 100 files at once for browser formats
- Quality settings — bitrate from 64 to 320 kbps
- Sample rate selection — from 22 to 96 kHz
- 500MB total limit — enough for most tasks
- No registration — just upload files and convert
