Convert Audio Files Instantly
Drop your file, pick the output format, and click Convert. The LAME encoder runs at 192 kbps VBR for high-quality MP3 output. Everything happens locally in your browser using WebAssembly — works on Windows 10, Windows 11, macOS, Linux, Chromebook, iPhone, and Android.
Shrink WAV and FLAC Files for Email and Phones
WAV and FLAC sound great but they are huge — a three-minute song can be 30 MB or more. Converting to MP3 at 192 kbps VBR brings that down to around 4–5 MB without a noticeable quality drop, which makes the file small enough to email, upload to a form, or sync to a phone with limited storage.
Make Voice Memos and WhatsApp Voice Notes Shareable
iPhone voice memos export as M4A, and WhatsApp voice notes are OPUS inside an OGG container — neither plays reliably in every email client, CMS, or slide deck. Convert to MP3 once and it plays on every phone, computer, and web player without fuss.
Convert FLAC to WAV for Editing or Mastering
Both formats are lossless, so converting FLAC to WAV preserves the full quality of the original. Some DAWs, video editors, and older hardware only read WAV — this gets your source material into the right container without a second round of lossy encoding.

Drop your WAV file into the converter, select MP3, and click Convert. The file is encoded locally in your browser using the LAME MP3 encoder at 192 kbps VBR. A three-minute WAV (about 30 MB) becomes a ~4 MB MP3.
Drop your FLAC, pick MP3, and convert. Useful when syncing to a phone, car stereo, or streaming upload that doesn't accept FLAC. For archival or editing, convert to WAV instead to stay lossless.
Share the voice memo to your computer via AirDrop or Files, then drop the M4A into the converter and select MP3. (If you're on iPhone, you can do it in Safari directly.) MP3 plays in every email client and web player, M4A doesn't.
Long-press the WhatsApp voice note and save it, then drop the OGG file into the converter and pick MP3. The result plays anywhere without WhatsApp installed.
Yes — we use the industry-standard LAME encoder at 192 kbps VBR, which is near-transparent for most music. If you need the absolute best quality, stick with WAV or FLAC (both lossless). Converting one lossy format to another (e.g. OPUS → MP3) always loses a little extra quality — that's how compression works.
WAV is uncompressed and lossless — large but perfect quality. FLAC is compressed and lossless — about half the size of WAV with no quality loss. MP3 is compressed and lossy — small and universal, with a tiny quality trade-off. OGG (Vorbis) is compressed and lossy — similar to MP3 but open-source and better at low bitrates.
No. The entire conversion runs locally in your browser using WebAssembly. You can verify this by opening the browser's Network tab during conversion — nothing outbound.
