Massive space savings
A minute of CD-quality WAV is about 10 MB; the same minute as a 192 kbps MP3 is about 1.4 MB — roughly 85–90% smaller, with differences that are hard to hear.
Limitations
We’d rather be upfront about what this tool can’t do yet:
- MP3 is lossy; keep the WAV originals if you’ll edit further.
- 300 MB per file.
FAQ
Frequently asked questions
Are my files uploaded?
No. Everything runs inside your browser on your own device, so your files are never sent to FreeToolsDaily or anyone else.
Why does the first conversion take longer?
The first time, your browser downloads the FFmpeg engine (about 30 MB). It’s cached afterwards, so later conversions start almost instantly.
Is there a file size limit?
Up to 300 MB per file. Processing happens in your browser’s memory, so very long or 4K videos may be slow on older phones.
