Frequently Asked Questions
Why convert MP3 to OGG?
MP3 (MPEG-1 Audio Layer 3) uses lossy compressed encoding and is best for universal music playback and sharing across all devices and platforms. OGG (Ogg Vorbis) uses lossy compressed encoding and excels at open-source software, Linux systems, game development, and streaming on open platforms. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Will I lose audio quality?
Both are lossy, so transcoding loses a little. At quality setting 6 (≈192 kbps) the difference from the source MP3 is inaudible for speech and most music. Keep the original MP3 archived if quality is critical.
Does OGG play everywhere?
Browsers (Chrome, Firefox, Edge) and VLC play OGG natively; Apple devices and Safari historically do not. For iPhone-bound audio, convert to AAC/MP4 instead.
Why does the first conversion take a while?
The FFmpeg engine (~30MB WASM) downloads once on first use and is cached after. Subsequent conversions start instantly, even offline.
Are my audio files uploaded?
No. Conversion runs entirely in your browser via FFmpeg.wasm. Files never leave your device.
