Is my your audio file file uploaded?

No. The conversion runs inside your browser with WebAssembly and native browser decoders. The file never leaves your device; you can watch the Network tab stay empty while it converts.

Is there a file size or daily limit?

No limit set by us. The only ceiling is your device's memory, because everything happens locally. There is no queue, no account requirement and no daily count.

How do I know the WAVE64 output is valid?

Every output is checked before it is offered: the bytes are re-read and the format signature, size and structure are verified. If a result cannot be validated it is not shown as a result.

Does it work on iPhone and iPad?

Yes. The same app runs in Safari and as the Omni Converter app on iOS, where Save opens the share sheet so the file lands in Files, Photos or any app you choose.

Audio format

Create Sony Wave64 PCM audio for large-file and professional production workflows.

Runs in your browser. Nothing is uploaded, nothing is stored, and the Wave64 output is validated before you see it.

Open the converterFree. No account. Drop several files at once if you like.

How it works

Drop, pick or paste your file. It is recognised the moment it lands.
Choose Audio to Wave64. Only conversions this file can really do are offered.
Save. One file, a bundle, or a whole folder. On iPhone the share sheet opens so it lands in Files or Photos.
