Convert FLAC files to OGG free in your browser — no signup, no install, and the file is never uploaded to a server. OGG compresses further, so the file gets noticeably smaller.
Add your FLAC file
Drag the FLAC file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm OGG as the output
OGG is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.
Run the conversion
Press the convert button. Audio decodes and re-encodes in your browser — a normal song finishes in a few seconds.
Download the OGG file
When it finishes, download the OGG file. Converting multiple files gives you the option to download them together as a ZIP.
A lossless format that preserves 100% of the original quality while roughly halving the size of a WAV. It is the standard among audiophiles.
A patent-free open-source lossy format, widely used in game audio and Linux environments, though some devices cannot play it.
Yes. FLAC to OGG conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the FLAC file never leaves your device. That is also why it works without an internet connection once the page has loaded.
OGG uses lossy compression, so some detail is discarded. At high quality settings the difference is usually invisible, and the file becomes far smaller.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
