OGA to WMA Converter

Convert OGA to WMA Online

OGA is Xiph.Org's audio-only Ogg file — an open, royalty-free container that usually holds Vorbis, sometimes Opus or FLAC. This converter re-encodes it to WMA (Windows Media Audio), Microsoft's proprietary lossy format built on the ASF container and released on August 17, 1999 as part of Windows Media Technologies 4.0. Convert to .wma when a legacy Windows program, an old in-car head unit, or a Windows Media Player library specifically expects that extension; for anything modern, OGA to MP3 or OGA to AAC is the more compatible pick.

How to Convert OGA to WMA

1. Upload Your OGA File: Drag and drop your .oga onto the page or click "Add Files." Queue several at once and they all run with the same settings.
2. Pick a Quality Preset: Leave it on the recommended preset, or open Quality Preset (Highest down to Lowest) to trade size against fidelity. The standard WMA codec tops out near 192 kbps, so the upper presets are already CD-grade.
3. Set the Bitrate or Trim (Optional): Switch File Compression to Constant Bitrate, Variable Bitrate, or Custom Bitrate for a predictable file size, and adjust Audio Channel or Audio Sample Rate to match the source. Use Trim to export only a start time and duration.
4. Convert and Download: Click Convert and save your .wma file individually or as a ZIP. No sign-up, no watermark.

OGA vs WMA — Format Comparison

Frequently Asked Questions

Will I lose quality converting OGA to WMA?

It depends on which codec is inside the .oga. If it holds Vorbis, Opus, or Speex — all lossy — then encoding to WMA is a second lossy generation, so detail the first encode discarded stays gone. Keep added loss minimal by matching or exceeding the source bitrate (for example, a 192 kbps Vorbis source to 192 kbps WMA). If the OGA carries FLAC (lossless), this is a clean first-generation WMA encode, exactly like encoding from WAV — use the High or Highest preset to preserve the master. Either way, a higher bitrate avoids stacking new artifacts on the old ones, and lossy encoding is never reversible, so keep the original if you might need full quality later.

Should I pick WMA v1 or WMA v2?

This converter defaults to WMA v2 (the audioCodec the WMA target selects automatically), the more efficient standard encoder, and that's the right choice for almost everyone — it delivers CD-quality audio in the 64-192 kbps range and is decoded by any reasonably modern Windows Media stack. WMA v1 is the original 1999 codec; choose it only if you're feeding a very old device or program that predates v2 support. Both are lossy; neither is the separate WMA Lossless variant.

Why convert to WMA instead of MP3 or AAC?

Mostly compatibility with legacy Windows tooling. Independent listening tests put modern Vorbis, AAC, and WMA close together at typical bitrates, and Microsoft's old "half the size of MP3" marketing was disputed by those tests — WMA holds no clear quality edge today. Its real disadvantage is reach: Apple's Music app, most phones, and many web players don't handle it. Convert to WMA only when something specifically requires .wma — otherwise OGA to MP3 plays on virtually anything, and OGA to AAC is the efficient modern pick.

Will my WMA file play outside of Windows?

Native WMA support is mainly a Windows and Windows Media Player story. Some third-party players (VLC, foobar2000) decode it, and many car head units — Toyota's USB audio, for instance — play WMA at up to 192 kbps alongside MP3 and AAC. But Apple devices, most smartphones, and a lot of modern browsers do not play it without a plug-in. If you need the audio to play broadly, keep an open copy with OGA to MP3 and reserve .wma for the one device or program that demands it.

How are my OGA files handled, and how long are they kept?

Your OGA is uploaded over an encrypted connection, converted to WMA on our servers, and the files are deleted automatically a few hours after conversion. There is no sign-up, no watermark, and your files are never shared or made public. In our testing, a 3-minute Vorbis .oga at the default preset re-encoded to 192 kbps WMA v2 produced a file of roughly 4.3 MB. On a big batch the practical limit is upload time, not a per-file size cap.
