Does this tool upload my audio file?

No. All file reading happens entirely in your browser using the Web Audio API and the File API. Your audio never leaves your device.

Which bitrate should I use for WMA output?

For music, 128 kbps is a good balance of quality and file size. For voice or podcasts, 64 kbps is sufficient. For archival quality, use 192 kbps.

Why does my OGG file show no duration?

Duration reading requires decoding the audio stream. If the file is very large or the browser cannot decode it quickly, the duration may show as unknown. The conversion commands still work regardless.

Can I convert in bulk?

Use the FFmpeg glob pattern shown in the bulk command tab: `ffmpeg -i input.ogg output.wma` works file-by-file, but a shell loop like `for f in *.ogg; do ffmpeg -i "$f" "${f%.ogg}.wma"; done` handles whole directories.

Is WMA still a good format?

WMA is a legacy format maintained for Windows compatibility. For modern use, consider AAC or Opus instead. WMA is best when targeting Windows Media Player or devices from the 2000s–2010s era.

Does FFmpeg support WMA encoding?

Yes. FFmpeg encodes WMA v2 via the `wmav2` codec, which is widely compatible with Windows Media Player and most WMA-capable devices.
