Frequently Asked Questions
- What audio formats are supported?
- The converter supports MP3, WAV, FLAC, OGG (Vorbis), AAC, M4A, WMA, AIFF, and more. You can convert between any combination of these formats. It uses FFmpeg WebAssembly which supports virtually every audio codec.
- Which audio format should I choose?
- For universal compatibility, use MP3. For lossless quality, use WAV or FLAC (FLAC is smaller). For Apple devices, M4A/AAC works well. For web use, OGG or MP3 are best. If you need to edit the audio, WAV is the safest choice as it's uncompressed.
- Can I convert video files to audio?
- For extracting audio from video files, use our extract audio tool which is specifically designed for that. This audio converter is optimized for converting between audio formats.
- Is there a file size limit?
- No. Since the conversion runs in your browser, there are no server-imposed limits. You can convert large audio files — podcasts, audiobooks, DJ sets — limited only by your device's available memory.
- How do I convert multiple audio files at once?
- Upload multiple files and the converter processes them sequentially. Each file is converted with your chosen settings. This is perfect for converting an album or batch of recordings from one format to another.
- Does converting audio between lossy formats reduce quality?
- Yes. Each lossy-to-lossy conversion (e.g., MP3 to OGG or OGG to MP3) involves re-encoding which can degrade quality slightly. For best results, always convert from the highest-quality source you have. If you have the original uncompressed WAV or FLAC, convert from that.
