What happens to your file
OGG files are common for games, open-source apps, web audio, but not every app or device opens them. MP3 is ideal for music libraries, podcasts, car stereos, any device. Spool converts OGG to MP3 with FFmpeg — real decoding and encoding, not a renamed file extension.
Lossy → lossy. Converting between compressed formats re-encodes the audio. Pick a bitrate equal to or above the source to avoid audible loss — re-encoding a 128 kbps file at 320 kbps won't make it sound better, but it won't make it worse either.

FAQ
What bitrate should I choose for MP3?
192 kbps is a good default for music. Choose 320 kbps for the best quality, 128 kbps for podcasts and voice, 64 kbps for small voice notes.
Can I convert several OGG files at once?
Yes. Drop up to 10 files at a time — each one is converted in parallel and you can download them individually or all at once.
Is there a file size limit?
Convert and edit files on your device. The browser edition accepts up to 100 MB total, media up to 10 minutes and video up to 4K. Codec availability and device memory can limit individual jobs.
Is this OGG to MP3 converter free and safe?
Yes. There are no pop-ups, redirects or fake download buttons, and no software to install. Files are transferred over HTTPS, processed in isolated job folders and deleted automatically.
