When to use it
When you actually need MP3
Email attachments
WAVs are huge. Convert to MP3 first so the file actually sends without bouncing past the size limit.
Phone & car playback
MP3 is universally supported — better for offline study, commuting playlists, and any non-audio-pro listening.
Embedded web audio
Smaller MP3 files load faster on websites. Use MP3 for the web, keep WAV as the master.
FAQ
Frequently Asked Questions
01 Why does FreeTextoSpeech download as WAV instead of MP3?
WAV is lossless and preserves the full quality of the Kokoro model output. Converting to MP3 introduces compression artefacts. We let you convert to MP3 yourself if your workflow requires it — the conversion is instant and free with any modern tool.
02 How do I convert the WAV to MP3?
On Mac, drag the file into iTunes / Apple Music and use "Create MP3 Version." On Windows use Audacity: File → Export → Export as MP3 (requires the free LAME encoder). Online converters like cloudconvert.com or CloudApp work too.
03 Will MP3 compression noticeably reduce voice quality?
At 128 kbps or higher, MP3 is effectively transparent for speech. Most podcast hosts and video editors accept 128 kbps MP3 without audible loss.
04 Can I batch-convert multiple WAV files to MP3?
Yes. Audacity supports batch processing via Chains (macOS/Linux: File → Macros). fre:ac is another free batch converter for Windows.
05 Is MP3 necessary for podcast distribution?
Most podcast hosts accept MP3 or M4A. Upload WAV to your host and it will handle conversion, or convert locally first for tighter control.
