WAV to OGG converter.

A WAV to OGG converter reads an uncompressed WAV file and saves the sound again as an OGG file, which is far smaller. This one writes OGG with Opus sound, at the quality you choose from 48 to 192 kbps. A three minute CD quality WAV is about 31.8 MB. At 128 kbps the OGG is about 2.9 MB, roughly eleven times smaller. It all happens in your browser, so no file is uploaded, there is no sign-up and there is no limit on how many files you convert.

How to convert WAV to OGG

1. Drop one or more WAV files on the box, or click to choose them. You can pick a whole folder's worth at once.
2. Each file turns into an OGG by itself, at the quality you used last time. 128 kbps is where it starts.
3. Open Opus quality and look at the sizes. Every option shows the size it gives for your file, and the OGG is made again when you change it.
4. Use Channels to make a stereo WAV mono. For speech and short sound effects that halves the work for the same quality.
5. Play the OGG in the page, then press Download the OGG. The name is kept, with .ogg at the end. With many files, press Download all as ZIP.

How much smaller is an OGG than a WAV?

A WAV stores every sample. CD quality is 44,100 samples a second, two channels, 16 bits each. That is 1,411,200 bits a second, or 176,400 bytes. An OGG file made here stores a fixed number of bits a second, so its size depends only on the length and the quality you pick. For a 3 minute (180 second) song:

The page shows the real size of your own file, which can differ a little from these numbers because of the headers and the way the encoder packs the last second.

Opus or Vorbis inside the OGG

OGG is only the box. The OGG files made here hold Opus sound, the newer codec, which current Chrome, Edge and Firefox play. Some older programs only open OGG Vorbis, and the file will fail to load in them even though it ends in .ogg. If your target lists only "Ogg Vorbis", check its documentation first, or test one file before you convert the whole folder. This page does not make Vorbis.

Picking a quality

• 192 kbps for music you want to keep close to the WAV.
• 128 kbps for most music and for sound where you can hear a difference. It is the default.
• 96 kbps for background music, a podcast with music or a game soundtrack where size matters.
• 48 to 64 kbps for voice, narration and short sound effects, in mono if the sound is only one voice.

Sound effects and game audio

A one second stereo effect saved as a 44.1 kHz WAV is about 176 KB. As mono OGG at 64 kbps it is about 8 KB, since 64 kbps is 8,000 bytes a second. Hundreds of effects add up, which is why games ship OGG. Cut the silence off the start of each effect before you convert, so it plays the moment it is triggered. The audio cutter does that in the browser. Opus works at 48 kHz inside, so a game engine may report 48 kHz for a file that came from a 44.1 kHz WAV. That is normal.

Common problems

• The page says it cannot read the file. Some WAV files use an unusual codec inside, such as ADPCM from old tools. Open them in an audio editor and export a plain 16-bit WAV first.
• The page says the browser cannot encode Opus. Use a current Chrome, Edge or Firefox. Safari may not make the file.
• The OGG will not play on an iPhone or in Apple Music. Apple's own apps do not open OGG. Use WAV to MP3 for those.
• A very long WAV fails. The file is handled in memory, so an hour of 24-bit sound may be too much. Close other tabs, or cut it into parts.

To go the other way, use OGG to MP3, or the audio converter for other formats.
