Audio to MP3 questions
Is the Audio to MP3 converter free?
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP3 itself beyond the free-plan badge.
Do I need to install any software?
No. The conversion runs on our servers and you use it from a browser tab, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where Audio plays: Varies by format. Where the MP3 you get back plays: Every device made in the last 25 years.
Does converting Audio to MP3 reduce the quality?
Audio to MP3 is a re-encode, so a small amount of detail is lost. At the default quality level the difference is inaudible on speech, and for music it stays well below what typical playback gear reveals.
How large a file can I convert?
Anything under 1GB per upload, which is more footage in some formats than others. Audio: Varies by format. MP3 coming back: Roughly a tenth of uncompressed audio. For anything bigger, trim or compress it first, both are free tools here.
Is my file kept private?
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
