Check the details

Choose MP3 or WAV

Audio Converter — FAQ
Is this audio converter really free?
Yes — convert as many files as you like, free, with no signup and no watermark. An optional Pro membership (NZ$9/mo) adds batch conversion for whole folders, but a single file is always fully free.
Is my audio uploaded anywhere?
No. Your file is decoded and re-encoded entirely inside your browser using the Web Audio API — it never leaves your device and nothing is stored on a server.
Which formats can I convert from?
Anything your browser can decode, which covers most common files: MP3, WAV, M4A/AAC, OGG, Opus and usually FLAC. If a file can’t be decoded, you’ll see a clear message — re-save it as MP3 or WAV first and try again.
Should I pick MP3 or WAV?
MP3 is best for sharing, podcasts and music — it’s small and plays on every device. WAV is uncompressed and full quality, handy when you’re importing into editing software like a Reel edit or a property video voiceover.
Can I convert a voice memo from my iPhone?
Yes. iPhone voice memos and recordings are usually M4A — drop one in and convert it to MP3 so it plays cleanly on any NZ client’s phone, PC or email. Great for sending a quick recording to a vendor or buyer.
Does it work on my phone?
Yes — it runs in any modern mobile or desktop browser, no app to install. Larger WAV files use more memory, so very long recordings convert fastest on a laptop.
