Frequently Asked Questions

What happens to audio quality when converting WMA to MP3?
Both formats use lossy compression. Re-encoding between lossy formats can cause slight additional quality loss, so it's best to convert from the highest quality source available.
Why is MP3 still widely used?
MP3 offers universal compatibility — every device, media player, and platform supports it. While newer codecs like AAC and Opus are technically superior, MP3's ubiquity makes it the safest choice for maximum compatibility.
Is there a file size limit for audio conversion?
You can convert audio files up to 50MB. Since processing happens in your browser using WebAssembly, larger files may take longer depending on your device's processing power.
Is my audio data kept secure?
Absolutely. Audio conversion runs locally in your browser using WebAssembly (FFmpeg). Your audio files are never transmitted over the internet — they stay on your device throughout the entire process.
