Extract Vorbis OGG audio from an MP4.
All processing happens in your browser — files never upload anywhere.
MP4 to OGG converts your MPEG-4 Part 14 (.mp4) files to Ogg Vorbis (.ogg) directly in your browser using FFmpeg WebAssembly (the same transcoder in VLC, HandBrake, and countless production apps, compiled to WASM). No signup, no watermark, no upload — your MP4 stays on your device from start to finish. Ogg Vorbis is typically used for royalty-free audio, common in games, and Toolspace's converter preserves the source at the highest quality the target format allows.

Every step runs on your device — nothing is uploaded.
Open Toolspace at https://toolspace.cloud/video/mp4-to-ogg. Nothing installs — the tool runs in your browser.
Drag your MP4 file into the drop zone or click to browse. Files stay local — no upload happens.
FFmpeg WebAssembly (the same transcoder in VLC, HandBrake, and countless production apps, compiled to WASM) handles the conversion in the background. Typical files convert in seconds.

Yes. MP4 to OGG on Toolspace is fully free with no watermark, no signup, and no OGG size cap. It's ad-supported so we can afford to give it away.
No. MP4 to OGG runs entirely in your browser using FFmpeg WebAssembly (the same transcoder in VLC, HandBrake, and countless production apps, compiled to WASM). Your MP4 never leaves your device — it's safe for confidential documents, sensitive photos, or unreleased media.
Ogg Vorbis is used for royalty-free audio, common in games. Converting to OGG makes sense when the receiving system requires it.
MP4 to OGG uses FFmpeg's default encoding profile for OGG — a well-balanced trade-off between quality and size. For lossless quality, prefer targets like WAV, FLAC, or lossless-WebM.
Roughly 30-60 seconds per minute of source video on a modern laptop. The first use of MP4 to OGG also downloads FFmpeg's WebAssembly core (~30 MB) — that download is cached forever afterwards.
Those services upload your MP4 to their servers to convert it. MP4 to OGG does everything in your browser — no upload, no server round-trip, and no rate limits. That means privacy for sensitive files and much faster conversions for large ones.
All free, all browser-based, all zero-signup.
