About MP3 to WAV
WAV cannot make an MP3 sound better, but it is the format editing tools work in natively: no decoding on every play, no generation loss when you cut and export, and sample-accurate positioning.
Choose 16-bit/44.1 kHz for CD and general use or 24-bit/48 kHz for video projects. The output is standard PCM WAV that every application reads.
How it works
- Drop your files onto the box above, click it to browse, or paste from the clipboard.
- Adjust the options if you need to — the defaults suit most cases.
- Press Convert. The work happens on your device, so speed depends on your computer or phone.
- Download the WAV — individually or all at once.
About the formats
MP3 · MPEG-1 Audio Layer III · .mp3
The audio format everything can play: cars, phones, old players, websites. Lossy, but at 192–320 kbps close to indistinguishable from CD.
- All MP3 patents expired in 2017; the format is now free to use.
- 128 kbps is the classic “good enough” rate; 320 kbps is the maximum.
- MP3 cannot store multichannel surround or lossless audio.
M4A · MPEG-4 audio (AAC) · .m4a
Apple’s audio format from iTunes, Voice Memos and the Music app: AAC audio in an MP4 container, better than MP3 at the same bitrate.
- M4A usually holds AAC; the .m4a from Apple Music purchases may be ALAC (lossless) instead.
- Voice Memos on iPhone save M4A; many transcription and Android apps prefer MP3.
- M4A supports chapters and cover art metadata.
AAC · Advanced Audio Coding · .aac
The successor to MP3 used by YouTube, Apple and broadcast: more efficient compression, usually wrapped in M4A or MP4.
- A raw .aac file is an ADTS stream without a proper container, so some players cannot seek in it.
- AAC at 128 kbps sounds roughly like MP3 at 160–192 kbps.
- AAC is the mandatory audio codec in MP4 video.
OGG · Ogg Vorbis / Opus audio · .ogg
The open-source audio container used by games, Wikipedia, Spotify streams and WhatsApp voice notes (Opus); not supported by Apple apps.
- Ogg is a container; the codec inside is usually Vorbis (music) or Opus (voice, low bitrate).
- Opus is the codec behind WhatsApp voice messages, Discord and WebRTC calls.
- iOS and iTunes do not play OGG natively, which is the usual reason to convert to MP3.
