WMA

Windows Media Audio

微软对 MP3 的回应，随 Windows Media Player 捆绑发布了十年之久。在 Windows 之外支持很差，因此通常会被转换掉而不是保留。

转换前值得了解

Both WebM and WMA are lossy formats, so repeated conversions can accumulate rounding artifacts. Keep this to only what you need and avoid repeated round-trips.
这次转换只会保留音轨 —— 画面会被完全丢弃。

FAQ

关于 WebM 转 WMA 的常见问题

这个 WebM 转 WMA 转换器是免费的吗？

是的。在这里把 WebM 转换为 WMA 完全免费，无需账号、没有水印、也没有每日次数限制。处理在你自己的设备上完成，因此不存在需要转嫁给你的服务器成本。

我的 WebM 文件会被上传到任何地方吗？

For browser-based pairs, your file is read locally and converted by ffmpeg in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.

WebM 转 WMA 有文件大小限制吗？

There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.

把 WebM 转换为 WMA 会损失质量吗？

WMA is a lossy format, so some detail is discarded when it is encoded. At the default quality setting the change is often not visually obvious; keep your original WebM file if you might need it again.

可以一次把多个 WebM 文件转换为 WMA 吗？

Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.

WebM 转 WMA 能在手机、Mac 或 Chromebook 上使用吗？

Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.

Why do some conversions take longer on first run?

The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.

I converted a file and the output is blank or unusable. What should I check?

Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
