WAV vs MP3 vs OGG — Which Format Should You Use?
Choosing the right audio format depends on your use case. Here is a practical guide to help you decide:
- WAV (PCM) — Uncompressed, lossless. Large file size but perfect quality. Best for editing, archiving, or sending to a mastering engineer. Use WAV when you need to re-edit or re-process later.
- MP3 — Compressed, lossy. Small file size with very good perceived quality at 128–320 kbps. Best for podcasts, music streaming, and web delivery. The most universally compatible format.
- OGG / Opus — Open-source, compressed. Better quality than MP3 at the same bitrate. Good for web apps and games. Not supported on all platforms (notably older iOS/Safari).
Common Conversion Scenarios
- Convert MP3 to WAV for import into a DAW (digital audio workstation) for editing
- Convert WAV to MP3 to reduce file size for sharing or uploading
- Convert FLAC or AAC to MP3 for compatibility with devices that don't support those formats
- Convert to OGG for use in HTML5 audio elements and web games
Frequently Asked Questions
Can I convert MP3 to WAV without quality loss?
The WAV output is lossless (uncompressed PCM). However, since the source MP3 is already lossy-compressed, converting it to WAV does not recover information that was lost during the original MP3 encoding. You will get an uncompressed version of what the MP3 contains — which is useful for editing but does not improve the original quality.
Which MP3 bitrate should I use?
128 kbps is suitable for speech (podcasts, voice recordings). 192–256 kbps is good for music. 320 kbps is the highest quality MP3 and is nearly indistinguishable from the original for most listeners.
Does OGG work in all browsers?
OGG export uses the browser's built-in MediaRecorder API. It works reliably in Chrome and Firefox. Safari has limited OGG/Opus support, so WAV or MP3 is safer if your audience uses Apple devices.
Are my files uploaded to a server?
No. The entire conversion process runs locally in your browser using the Web Audio API. Your files are not sent anywhere.
