Frequently Asked Questions

Which audio formats does the converter support?▼
MP3, WAV, OGG, FLAC, and AAC for both input and output. Most common audio formats are supported.
Does converting audio reduce quality?▼
WAV and FLAC are lossless formats — no quality loss. Converting to MP3 involves lossy compression, but at 192kbps or higher the difference is inaudible to most listeners.
Can I set the output bitrate?▼
Yes. Choose from 64, 96, 128, 192, 256, or 320 kbps for MP3 output. Higher bitrates produce better quality but larger files.
Is the conversion done in the browser?▼
Yes. FFmpeg.wasm handles all conversion locally in your browser. Your audio file is never uploaded to any server.
What is the best format for music vs voice recordings?▼
For music: FLAC (lossless) or MP3 at 320kbps. For voice/podcasts: MP3 at 128kbps provides excellent quality at a small file size.
