About this tool
Sound effects and music exported from a DAW are WAV files ten times larger than they need to be. Game engines, mods, and web games want OGG Vorbis: small, royalty-free, and loop-friendly. Drop in a folder of WAVs and get OGGs back in seconds, all processed locally.
About the formats: WAV stores uncompressed PCM audio: perfect quality, but around 10 MB per minute. It is the format audio editors, samplers, and studios expect. OGG files hold Vorbis or Opus audio, open formats used by games, Linux software, and some voice recorders. Quality per megabyte is excellent, but device support outside the desktop is spotty.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your WAV files into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click Convert to OGG and wait a moment.
- Download the results individually or all at once as a ZIP.
Frequently asked questions
Which quality should I use for game audio?
q4-q5 for sound effects, q6 for music. Higher settings mostly add file size.
When should I keep WAV instead?
Very short, latency-critical sounds (footsteps, UI clicks) are sometimes kept as WAV so the engine can play them without decoding. Everything else benefits from OGG.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
