How it works
Common questions
Why convert WAV to MP3?
WAV files are uncompressed and can be enormous — a single song can be 30–50 MB. MP3 uses lossy compression to reduce file sizes by 80–90% while maintaining audio quality that's indistinguishable to most listeners. This makes MP3 ideal for streaming, sharing, and everyday listening, while WAV is better kept as a master archive format.
Will I lose audio quality converting WAV to MP3?
Some quality is lost because MP3 is a lossy format — it discards audio data the human ear typically can't detect. Formatly converts at 192 kbps by default, which is considered high quality and virtually indistinguishable from the original WAV for most listeners. If you need archival quality, keep the WAV and convert a copy to MP3.
What bitrate does Formatly use for MP3 output?
The default output bitrate is 192 kbps, which balances file size and quality well for music and podcasts. If you need a different bitrate, upgrade to Pro where you can set custom bitrate options (128 kbps, 192 kbps, 256 kbps, 320 kbps).
Is there a file size limit?
Free users can convert WAV files up to 25 MB without an account, or up to 10 conversions per day with a free account. Pro users get 500 MB per file and 3,000 credits a month. Business users get up to 5 GB.
