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.

OGG to WMA Converter

Drop an OGG file to read its metadata, then get ready-to-run FFmpeg and VLC commands to convert it to WMA format.

Target WMA Quality

64 = voice/podcast · 128 = music · 192 = high quality

Conversion Commands

Run these on your own machine. No upload required.

Install FFmpeg

Windows: winget install Gyan.FFmpeg | macOS: brew install ffmpeg | Linux: sudo apt install ffmpeg

Single-file command

ffmpeg -i "input.ogg" -c:a wmav2 -b:a 128k "output.wma"

Flags explained: -c:a wmav2 — WMA v2 encoder · -b:a 128k — audio bitrate (adjust with quality selector)

Summary

OGG (Vorbis) and WMA (Windows Media Audio) are both lossy audio codecs, but WMA is required for older Windows Media Player setups and certain embedded devices. This tool reads your OGG file's metadata directly in the browser — no upload needed — and generates the exact FFmpeg or VLC command-line instruction to convert it to WMA on your own machine.

How it works

Drag and drop an OGG file onto the drop zone (or click to browse).
The tool reads the file name, size, duration estimate, and MIME type client-side using the Web Audio API.
It displays file metadata in a clean summary panel.
Copy the generated FFmpeg or VLC command for your operating system.
Run the command in your terminal or Command Prompt to convert the file locally.

Use cases

Convert OGG game audio or podcast files to WMA for Windows Media Player.
Prepare audio for older Windows devices that do not support OGG playback.
Batch-convert OGG files using the generated FFmpeg one-liner.
Check an OGG file's basic metadata before converting.
Generate a VLC conversion command for users without FFmpeg installed.
Understand the correct bitrate flags for OGG-to-WMA transcoding.
