How do I convert MP3 audio to OGG without quality loss?
+
Upload the MP3 file and our converter chooses the OGG codec / bitrate combination that matches the source. Lossless target (OGG = WAV / FLAC / ALAC) preserves every sample; lossy target (OGG = MP3 / AAC / OGG) defaults to 192 kbps which is transparent for spoken-word audiobooks and most music.
What bitrate does the OGG file use?
+
Default is 192 kbps for lossy OGG; pass-through for lossless OGG. Override to 320 kbps for audiophile or 64-96 kbps for spoken-word audiobooks (transparent for voice, halves the file size).
Will going from MP3 to OGG reduce my audio quality?
+
If MP3 is lossy and OGG is lossless (e.g. MP3 → WAV), the OGG file is no better than the MP3 — you can't recover information that's already been thrown away. If MP3 is lossless and OGG is lossy, expect the OGG codec to recompress; at 192 kbps this is transparent for most content.
Does the MP3 to OGG converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, album art, and chapter markers (important for audiobooks) are read from MP3 and written into the OGG container where the OGG format supports tags. M4B audiobook structure round-trips into M4B and AAX → M4B output.
Can I batch convert hundreds of MP3 files to OGG?
+
Yes — drop a folder of MP3 files in and we process them in parallel. Premium has more parallel workers and no per-file size cap, so a 500-file batch finishes in minutes rather than tens of minutes.
Will the OGG keep the same sample rate as MP3?
+
By default yes (48 kHz MP3 → 48 kHz OGG). If you need to downsample for compatibility (e.g. 96 kHz → 44.1 kHz for CD burning) the advanced sample-rate option does this with high-quality resampling.
Can I normalize loudness in the MP3 to OGG step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the OGG output, targeting -14 LUFS (streaming standard), -16 LUFS (podcast standard), or -23 LUFS (audiobook standard). Useful when batch-converting tracks with varying mastering levels.
Will the OGG play on my car stereo / iPod / audiobook app?
+
MP3 plays universally. AAC plays on Apple, most Android, Sonos. FLAC plays on Sonos and Android, less well on older iPods. M4B audiobooks play with chapter navigation on iOS Books, Audiobookshelf, and Smart Audiobook Player. The advanced options include device presets.
Is my MP3 file private during conversion?
+
Yes — uploaded MP3 files are processed in isolated workers and deleted within minutes. We never play, store, or share the audio content. Especially important when working with personal audiobook libraries.
How long does converting a 10-hour audiobook MP3 to OGG take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 10-hour audiobook finishes in 60-120 minutes. Chapter markers survive the round-trip and split cleanly.
Why is the OGG file louder / quieter than the MP3 source?
+
No automatic gain change happens unless you turn on the normalize option. If you do see a level change, your audio player or media library may be applying ReplayGain or per-track normalization on playback — not us.
Can I convert DRM-protected MP3 downloads to OGG?
+
No — DRM-encrypted MP3 (Audible AAX with personal activation, Apple Music) is encrypted at the bit level and we can't process it. Sources from public-domain audiobook archives, your own recordings, or Bandcamp downloads convert fine.
