OGG to WAV
Convert OGG Vorbis to uncompressed WAV in your browser — no upload, no server queue. 16- or 24-bit PCM output for editors, DAWs and game engines. No upload — runs 100% in your browser
or click to browse
How to use this tool
- Drop your .ogg file on the box above, or click to browse.
- Set bit depth and sample rate (defaults: 16-bit, 44,100 Hz).
- Your browser decodes the Vorbis audio locally and the page writes uncompressed PCM.
- Click Download — the whole process stayed inside your browser.
What an OGG file actually contains
OGG is a container, not a codec — the same way a .mkv file can hold several video formats. In practice an .ogg file almost always carries Vorbis, the open lossy codec that Firefox, Spotify's desktop library and a long tail of game engines adopted. Vorbis has no patents attached to it, which is why indie games in particular shipped with it for years.
This distinction matters when something goes wrong: an OGG file can in principle also contain Opus, FLAC or even video, and browsers differ in which of those they will decode. The page uses your browser's own decoder, so support follows whatever your build shipped with. If decoding fails you get a clear error rather than a silent bad result — unlike the common converter services that hand back a file of silence.
Converting Vorbis to PCM
Vorbis is lossy, so the same honesty applies here as with any lossy source: turning it into WAV does not recover anything. What you get is the decoded waveform, stored uncompressed so that editors can work without repeatedly decoding and re-encoding the compressed original.
The most common reason to do it is a game asset pipeline: many engines and older audio middleware libraries want PCM at import time. The second is archiving speech recognition data or training audio, where downstream tools expect WAV headers.
Size and settings
Uncompressed stereo at 44,100 Hz / 16-bit costs 1,411.2 kbit/s — 10,584,000 bytes per minute, about 10.09 MiB. Vorbis files are usually stored somewhere between 128 and 192 kbit/s, so expect the WAV to come out roughly seven to eleven times larger than whatever you dropped in.
| Source and target | Size relationship |
|---|---|
| 1 minute stereo Vorbis (~160 kbit/s) → WAV 16/44.1k | ~1.2 MB becomes ~10.09 MiB |
| 1 minute stereo Vorbis → WAV 24/48k | ~1.2 MB becomes ~16.48 MiB |
| 1 minute mono Vorbis → WAV 16/44.1k | ~0.6 MB becomes ~5.05 MiB |
Which settings to pick
16-bit / 44,100 Hz for anything going back into a game, a video timeline or a CD. 24-bit only when you will process the file further — the extra bits buy headroom during mixing, not audible quality in playback. As with every converter here, you choose the output rate explicitly because the Web Audio API resamples during decode and does not expose the source file's original rate to the page.
Frequently Asked Questions
Does converting OGG to WAV improve the quality?
No. Vorbis already discarded data when it compressed the audio. The WAV holds the decoded result without making it worse, but nothing lost can be recovered. To keep full quality you need either the original uncompressed master or a lossless copy of the same recording.
Is the OGG file uploaded to a server?
No. Decoding uses your browser's own audio engine and the WAV is built by JavaScript on this page. Nothing is transferred, so there is nothing to delete afterwards and no file size limit imposed by anyone else's storage.
Why would my OGG file fail to decode?
Either the payload is not the usual Vorbis (an OGG container can also hold Opus or FLAC, and support varies by browser and version), or the file header is damaged. The browser reports failure rather than producing silence, which is exactly what you want from a converter.
Can I convert OGG files from older games?
Usually yes — game audio of that era was typically Vorbis in an OGG container, sometimes with thousands of very short files. This page converts one file at a time; for bulk jobs a command-line run of ffmpeg or oggdec is more practical than a browser.
How much bigger will the WAV be?
Roughly seven to eleven times, depending on how your file was encoded. Vorbis typically sits between 128 and 192 kbit/s while uncompressed 16-bit stereo at 44,100 Hz runs at 1,411.2 kbit/s — about 10.09 MiB per minute.
What bit depth should I use?
16-bit for playback and delivery — it is what CD uses and matches the dynamic range of real programme material. Choose 24-bit only if the audio is going into further mixing or restoration work, where its roughly 48 dB of extra theoretical headroom prevents accumulated rounding.
Will the output keep my tags and artwork?
No. The result is a plain PCM WAV with no metadata chunks, so Vorbis comments and cover art are dropped. Keep the original file if those matter to you.
Does this work offline?
Yes, once the page has loaded. The conversion needs no network at all — you can load the page, disconnect, and convert files for as long as the tab stays open.
Can I get mono output to halve the size?
Yes. Tick 'Mix down to mono' and the channels are averaged per sample. Halving for voice recordings is sensible and loses nothing for speech, but for music it collapses stereo placement permanently, so keep your original.
