Is this WMV to OGG converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple WMV files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

What bitrate will the converted audio use?

We default to 192 kbps for MP3, 128 kbps for OGG/Opus, and 320 kbps for M4A/AAC. These settings are perceptually transparent — most listeners can't tell the difference in a blind test.

Will my metadata (ID3 tags, album art) be preserved?

Yes, when both formats support it. Tags carry over on conversions like MP3→M4A or FLAC→MP3. WAV has limited tag support, so some metadata may not transfer.

Is OGG supported on Linux out of the box?

Yes — OGG Vorbis is natively supported by GStreamer, PulseAudio, and virtually every Linux audio framework. It's the default audio format for many Linux-first applications.

Can I use OGG extracted from WMV in a web application?

Yes — OGG Vorbis plays in Chrome, Firefox, and Edge. For Safari, provide an AAC alternative. OGG is a reliable choice for web audio alongside an AAC fallback.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert WMV to OGG?

WMV is about as far from open-source as a format can get. It is a proprietary Microsoft container with a proprietary Windows Media Audio codec, and it sits behind patent licensing that open-source projects cannot easily accommodate. For Linux users, open-source game developers, and anyone working with patent-free formats by principle or necessity, WMV is simply off the table.

OGG Vorbis is the open alternative. Developed by the Xiph.Org Foundation, it is entirely free of patents, royalties, and proprietary dependencies. Linux media players handle it natively. Unity and Godot use it as their default audio format for game assets. Icecast streaming servers were built around it. Firefox has supported it since day one.

Converting WMV audio to OGG lets open-source pipelines finally consume content that was stuck in a proprietary format. The WMA audio is decoded and re-encoded as Vorbis. Quality is good at standard bitrates, and file sizes are competitive with MP3. The main trade-off is device compatibility — OGG is not supported natively on iOS or older hardware. If your audience is primarily Linux, game engines, or web browsers, OGG is excellent. If you need maximum portability, consider MP3 instead.

Quality & file size: WMV to OGG

Typical file sizes: WMV 50–150 MB → OGG 2–5 MB.

Both WMV and OGG use lossy compression. We transcode at high quality settings (equivalent to OGG's recommended web quality) to minimize generational loss.

Color depth: WMV supports standard color, OGG supports standard color.

Transparency: WMV does not support transparency. OGG does not support transparency — transparent areas become solid white.

Your WMVfiles are converted 100% inside your browser. They are never uploaded to our servers, never stored, and never seen by anyone other than you. This isn't a privacy policy claim — it's an architectural guarantee: our server has no endpoint that receives file bytes.
