Convert audio in three steps
Drop your file, pick the format you need, and download, all in your browser.
Any format, either direction
MP3, M4A, WAV, FLAC, OGG, Opus, AIFF, WMA and more. Pick a target format and convert in one step. For example, an .aiff voice memo straight off a Mac becomes a compact .mp3 that plays anywhere.
Runs inside the page
Your file is decoded and re-encoded right there in the tab, so it never reaches a server.
Converting just to transcribe?
If you’re only converting so you can transcribe it, you can skip this step: Hushscript takes the original file, in almost any format, and extracts the audio itself before transcribing with speaker labels. You start with 30 free minutes.
Frequently asked questions
Does my file upload?
No. The conversion is done by code running inside the page, so the file never leaves your device.
Is it free?
Yes. There's no account, no watermark, and nothing to install.
Which formats can I convert?
MP3, M4A, WAV, FLAC, OGG, Opus, AIFF, WMA and more; pick any target format from the list.
Which format should I pick?
MP3 or M4A for small, shareable files; WAV or FLAC if you need lossless quality.
Is there a file-size limit?
No fixed limit, but everything runs in your browser's memory, so very large files can struggle on older devices.
Can I transcribe it?
Yes. Feed the converted file to Hushscript for a transcript with speaker labels; the first 30 minutes are free to try.
