Frequently Asked Questions
Why convert WAV to MP3?
WAV (Waveform Audio File Format) uses uncompressed lossless encoding and is best for professional audio editing, mastering, and archival in DAWs and production software. MP3 (MPEG-1 Audio Layer 3) uses lossy compressed encoding and excels at universal music playback and sharing across all devices and platforms. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
How much smaller does MP3 get?
Roughly 10×: a 50MB WAV becomes ~5MB at 192 kbps. WAV stores every sample; MP3 discards what ears can't hear. Archive masters as WAV/FLAC, share as MP3.
Which bitrate should I pick?
320 kbps for music libraries, 192 kbps for general sharing (transparent to most ears), 128 kbps for speech/podcasts. Below 128, cymbals and stereo imaging audibly degrade.
Will it play everywhere?
Yes — MP3 is the universal audio format: every phone, car, browser, and speaker supports it. That compatibility is the entire reason to convert from WAV.
Does converting back restore quality?
No. MP3→WAV inflates file size without recovering discarded detail. Always keep the original WAV if you might need full quality later.
When using WAV to MP3, are my files uploaded?
No. Conversion runs entirely in your browser via FFmpeg.wasm. Files never leave your device.
