VOC to OGG Converter
FileFlip converts VOC to OGG entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a VOC file to OGG?#
- Drop your VOC file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to OGG and the conversion starts on its own. FileFlip usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, then runs WebCodecs and FFmpeg on your own machine.
- Save the OGG file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting VOC to OGG lose quality?#
Sometimes. When the codecs inside the VOC file are ones the OGG container can hold, the streams are copied straight across and nothing at all is lost. When they are not, the file has to be decoded and encoded again, and that step does cost a little quality.
Is it safe to convert VOC files online?#
Yes, because nothing is uploaded. FileFlip converts VOC files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What VOC to OGG actually does to the file#
Converting VOC to OGG runs on WebCodecs and FFmpeg, usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, copies the streams through when the codecs fit and re-encodes when they do not.
| Engine | WebCodecs and FFmpeg |
|---|---|
| Conversion path | One step: VOC → OGG |
| Downloaded to your browser | Nothing in most browsers, or 30.8 MB if yours cannot encode these codecs itself |
| Quality | Lossless when the codecs fit, lossy when they do not |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Encoded streams | Sometimes | Survives for some files and not others. |
Worth knowing before you start:
- whether the browser can do this without FFmpeg depends on the codecs it exposes through WebCodecs
- the encoded streams are copied when the file's codecs fit the target container, and re-encoded when they do not
What is a VOC file?#
A VOC file holds audio in Creative Voice File format, the format Creative Labs introduced alongside the original Sound Blaster card in 1989 for storing digitized speech and sound effects in DOS-era games.
VOC mainly shows up today inside old DOS games and their emulation via DOSBox, where the original sound assets were never converted to a newer format.
Convert VOC to WAV to play or edit the audio in current software, since almost every modern audio tool reads WAV and very few still read VOC.
What is an OGG file?#
An OGG file is an Ogg-container file that, under the Xiph.Org Foundation's own naming convention, holds audio encoded with the Vorbis codec, an open, royalty-free lossy compressor comparable to MP3 or AAC.
Use OGG for Vorbis-encoded audio on Linux, in games, or anywhere royalty-free lossy compression matters more than universal playback.
Convert OGG to MP3 or AAC when the destination device or software has no Vorbis decoder, which is still common on Windows and iOS without a third-party player.
VOC to OGG questions people ask#
What creates a VOC file?
VOC files come from Creative Labs' own Sound Blaster recording software and from DOS-era games that shipped their speech and sound effects in this format, since VOC was the native audio format for early Sound Blaster cards.
What still opens VOC files?
Audacity and VLC open VOC files on any current operating system, and DOSBox reads them as part of running the original DOS games they came from. Mainstream media players generally do not support the format.
What should I convert a VOC file to?
Convert VOC to WAV for the widest compatibility with current media players and audio editors. Most VOC files hold uncompressed PCM data, so converting to WAV loses nothing.
What's the difference between OGG and OGA?
OGG and OGA are the same Ogg container format with different extensions marking what's inside. Since 2007, Xiph.Org's convention reserves .ogg for audio specifically encoded with Vorbis, while .oga is the codec-agnostic extension for Ogg audio that might hold Vorbis, FLAC, Speex or another codec. In practice many tools ignore the distinction and use .ogg for any Ogg audio.
