Quick answer: To convert WMA to OGG, add the WMA file to the iHateFiles WMA to OGG converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Re-encodes the audio into OGG.
Should you convert WMA to OGG?
Do this when OGG plays somewhere WMA does not. It is a second round of lossy compression, so set the bitrate at or above the original.
Both WMA and OGG are lossy
WMA (Windows Media Audio) has already discarded some of the sound, and OGG (Vorbis) will discard a little more. The OGG encoder works from the WMA, not the original recording, so pick a bitrate at or above the source. A lower one saves space and costs quality you cannot get back.
Where the OGG will play
OGG plays on Android, Firefox, Chrome and games, but not Apple Music or older players.

What usually goes wrong
About the WMA. A WMA bought from an early music store may be DRM-locked, and no conversion can lawfully unlock it. A WMA you ripped yourself converts without any trouble.
About the OGG. Ogg is the container, Vorbis is the codec, and an .ogg file can also contain Opus or FLAC. That is why one .ogg plays somewhere another will not.
How to convert WMA to OGG
- Add your WMA file. It is read from your disk and stays there.
- Check the settings. The output format is already set to OGG.
- Press convert and the OGG file is saved back to your device.
Questions
How do I convert WMA to OGG?
Open this page, add your WMA file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this WMA to OGG converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to OGG lose quality?
OGG is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several WMA files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
