Opus vs WMA at a glance

Opus is the modern voice and streaming codec behind WhatsApp voice notes and Discord calls — excellent quality at tiny file sizes, but not widely supported by standalone music players or older devices. WMA is Microsoft's proprietary audio format for Windows Media Player — rarely supported outside Windows, and most phones, apps and streaming platforms can't play it at all.

Opus to WMA — frequently asked questions

Is this Opus to WMA converter really free?

Yes — completely free, with no sign-up, no watermarks and no daily limits.

Will I lose quality converting to WMA?

WMA uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.

Is the conversion private?

Audio conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
