About WMA to MP3 conversion
WMA is the format Windows Media Player produced for years, so it is what old CD rips, ripped audiobooks and inherited music libraries are still sitting in. Microsoft moved on, and today an iPhone, an Android phone, a Mac or a modern car stereo will not touch a .wma file.
Converting to MP3 makes an old library playable again on current devices, and the whole job runs on your own machine with WebAssembly FFmpeg — useful when the library is large, because there is no upload step and no per-file limit.
Frequently asked questions
Yes — select or drag in as many files as you like and they are converted one after another in your browser, then offered as a single ZIP download. This is the usual way to migrate an old Windows Media library.
No. Tracks bought from old DRM-era stores carry protection that cannot be decoded, and no converter can lawfully remove it. Files you ripped yourself from your own CDs are unprotected and convert normally.
The standard ones — WMA v1 and v2, which is what Windows Media Player wrote by default and covers essentially every ordinary rip. The rarer Pro and Lossless variants are not supported.
No. The conversion runs entirely in your browser using WebAssembly (FFmpeg). Your recording never leaves your device — that is also why there is no upload wait, no queue and no file-size pricing. For personal recordings, lectures and meetings this matters more than anywhere else.
Up to 8GB on desktop browsers and 2GB on mobile — big enough to pull the audio out of a multi-hour lecture or meeting recording. There is no limit on the number of files, no signup and no watermark.
192kbps, which is transparent for speech and very close to transparent for music. The audio stream is decoded once and encoded once — there is no extra generation loss from server-side re-processing.
Yes — completely free and unlimited, with no watermark, signup or daily quota. Because the conversion runs on your own device instead of our servers, there are no processing costs to charge for.
Yes. It runs in any modern browser — Chrome, Safari, Edge or Firefox — on Windows, macOS, ChromeOS, Linux, iOS and Android. There is nothing to install.
Audio-only work is fast: there is no video to re-encode, so even the soundtrack of a long video converts in well under real time. Files whose audio is already MP3 are rewrapped without re-encoding and finish in seconds.
