Convert OGG to WAV
An uncompressed WAV from any OGG file, ready for editing, samplers and game engines.
- Nothing is uploaded
- Works offline after first use
- Open source
- No sign-up, no watermark. The limit is your device’s memory (phones hold less).
Convert OGG Vorbis or Opus audio to uncompressed WAV in your browser, for audio editors, game engines and samplers. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The limit is your device’s memory, which is smaller on a phone, and after your first run the page works offline.
Your iPhone may take a few seconds to prepare the video first, longer if it's stored in iCloud.

WAV is what you convert to when the audio is going into something else. Samplers and hardware drum machines, older DAWs, some game engines and modding tools, video editors on slower machines and speech-analysis software all prefer plain PCM WAV over compressed OGG. Converting once saves them decoding the Vorbis every time the sound plays or the project reloads.
The OGG is decoded by your browser’s built-in Vorbis or Opus decoder and written as a standard 16-bit, 44.1 kHz WAV by a small writer in this page. No compression is applied on the way out, so the WAV holds exactly what the decoder produced. It will be large, roughly ten times the OGG, at about 10 MB per stereo minute.
Nothing is uploaded. Game assets you are modding, samples you are building a kit from, and recordings you are cleaning up stay on your machine, and a folder of files converts in one go.
Game modders meet OGG constantly: Unity, Godot, RPG Maker, Minecraft resource packs and many indie titles ship their music and sound effects as Vorbis. Pulling a sound out, editing it in Audacity or a sampler, and putting it back often means a round trip through WAV. Convert the OGG here, edit the WAV, then export back to OGG from your editor.
How it works
- Drop one or more OGG files, or tap to pick them.
- WAV is already selected. Choose mono for single-voice recordings to halve the size.
- Convert. Each WAV downloads; several come as a zip.
In your browser, not on a server
Your browser decodes the sound track with the same audio decoders it uses to play media on any website (AAC for MP4, MOV and M4A; Opus or Vorbis for WebM; FLAC, WAV and MP3). The samples are resampled to 44.1 kHz and handed to LAME, the reference MP3 encoder, compiled to WebAssembly and served by this site. WAV files are written directly by a few lines of code in the page. Everything happens in memory in your tab.
Compared with upload-based tools: Online converters upload the whole video just to keep its sound, cap free files at a few hundred megabytes, and make you wait in a queue. Home videos, lectures and voice memos are personal. Here the file never leaves your device, so a 1 GB video converts as fast as your computer can read it, and the limit is your device’s memory (phones hold less).
Verify it yourself. Give the page a short while after your first run to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Does converting OGG to WAV improve the sound?
No. It stops further loss, but whatever Vorbis discarded when the OGG was made stays gone. The WAV is a faithful, uncompressed copy of the decoded audio.
What format is the WAV exactly?
PCM, 16-bit, 44.1 kHz, stereo or mono. Every audio program, sampler and game engine reads it. Audio at other sample rates, such as the 48 kHz used by Opus, is resampled to 44.1 kHz.
Will loop points from game files be kept?
No. Loop markers stored in OGG comments are not written to the WAV; set them again in your editor or engine.
Can I convert Opus voice notes to WAV for transcription?
Yes. Many transcription and speech-analysis tools prefer WAV. Choose mono to halve the size; speech loses nothing from being mono.
Is the file uploaded anywhere?
No. There is no server in this process. The page is a static file and the work is done by code running inside your browser tab. Give the page a short while after your first run to save itself for offline use; then you can turn off Wi-Fi and it still works.
