FLAC to OGG Converter

Converting FLAC to OGG Vorbis re-encodes a lossless archive into a smaller, royalty-free lossy format popular with Linux distros and game engines. Starting from lossless source means the encoder has clean input, so the output is as good as Vorbis gets at that bitrate.

What changes when you convert FLAC to OGG

Vorbis is lossy; the encoder discards psychoacoustically masked content. Quality is generally indistinguishable from the FLAC at quality level 6 or higher, and still very good at level 4. You can't recover detail from the OGG, so keep the FLAC as your source of truth.

When to use this conversion

  • Building music assets for a Unity, Godot, or Unreal project where Vorbis is the native format
  • Shipping audio in an open-source Linux application that avoids patented codecs
  • Creating smaller portable copies for Android devices where Vorbis is natively supported
  • Encoding for web playback where most browsers except Safari handle Vorbis

Where the output plays

OGG runs on Android, Linux, Windows with codecs, modern browsers, and game engines. iOS doesn't play Vorbis natively; use AAC if you're targeting Apple devices.

About these formats

FLAC (Free Lossless Audio Codec)

FLAC is a lossless compressor: it shrinks PCM audio to roughly 50–60% of its original size and decodes back to a bit-perfect copy. It supports tags, cue sheets, and up to 32-bit / 655 kHz, which makes it the de facto format for CD rips and audiophile music libraries.

OGG (Ogg Vorbis)

OGG Vorbis is a royalty-free lossy codec developed by Xiph.Org. At comparable bitrates it sounds cleaner than MP3, especially at 96 kbps and below, and it's the audio format used by Spotify's streams, most modern games, and open-source projects that want to avoid patent encumbrances.

How It Works

  1. Add your FLAC files Drag FLAC files onto the page, or click to pick them from your file browser. Batch uploads are fine.
  2. Choose OGG settings Pick bitrate or quality level for the OGG output. Defaults match common target use cases.
  3. Convert in your browser FFmpeg runs locally via WebAssembly. Nothing uploads. Progress shows per file so you know exactly what's happening.
  4. Download OGG files Grab each converted file individually, or download the whole batch as a single ZIP.

FAQ

What Vorbis quality level matches FLAC?

Quality 6 (around 192 kbps VBR) is transparent for most listeners on most program material. Quality 8 (around 256 kbps) is transparent to nearly everyone. You won't gain much perceived quality above that.

Is OGG better than MP3 for this conversion?

Generally yes, especially at lower bitrates. Vorbis is newer, handles voice and cymbals more cleanly, and doesn't carry MP3's patent history. MP3 wins only on universal device compatibility.

Are my files private?

Yes. The converter runs entirely in your browser using FFmpeg compiled to WebAssembly. Your audio files are never uploaded, never sent to a server, and never leave your device.

Is there a file size limit?

There's no hard limit, but because everything runs in your browser you're bounded by available memory. Files over about 2 GB total can get slow or hit browser memory limits. Process in smaller batches if you run into issues.
