AIFF till MP3 Vanliga frågor om konvertering
How do I convert AIFF audio to MP3 without losing quality?
+
Upload the AIFF file and the converter chooses the MP3 codec and bitrate to match the source. Lossless MP3 (WAV / FLAC / ALAC) preserves every sample bit-identically; lossy MP3 (MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears.
What bitrate will the resulting MP3 file use?
+
Default is 192 kbps for lossy MP3; pass-through for lossless MP3. Override to 320 kbps for audiophile or 96 kbps for voice / podcast. The choice trades file size against audible fidelity; below 96 kbps lossy artifacts become noticeable on music.
Will going from AIFF to MP3 reduce my audio quality?
+
If AIFF is lossy and MP3 is lossless (e.g. MP3 → WAV), the MP3 is no better than the AIFF — you cannot recover information already discarded. If AIFF is lossless and MP3 is lossy, the MP3 codec recompresses; at 192 kbps the result is transparent for most content.
Does the AIFF to MP3 converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and album art are read from the AIFF container and written into the MP3 container where the format supports tags. All common targets (MP3, AAC, FLAC, OGG) handle tags fine; raw WAV does not.
Can I batch convert hundreds of AIFF files to MP3?
+
Yes — drop a folder of AIFF 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 MP3 keep the same sample rate as AIFF?
+
By default yes — 48 kHz AIFF stays 48 kHz in MP3. If you need to downsample for compatibility (96 kHz → 44.1 kHz for CD burning), the sample-rate option applies high-quality resampling in the same encode pass.
Can I normalize loudness when converting AIFF to MP3?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the MP3, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batching tracks mastered at varying levels.
Will my MP3 play on car stereo, iPod, and Sonos?
+
MP3 plays everywhere. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and Android but not on older iPods. WAV plays on everything but is huge. The advanced device-preset dropdown picks a MP3 codec optimized for your target hardware.
Is my AIFF file private during conversion to MP3?
+
Yes — uploaded AIFF files are processed in isolated workers and deleted within minutes. We never play back, store long-term, or share the audio content. The full retention window is in /privacy/.
How long does converting a 1-hour AIFF to MP3 take?
+
Same-codec re-mux: 10 to 30 seconds. Re-encode to a different codec: typically 10 to 20% of source duration, so a 1-hour AIFF → MP3 finishes in 6 to 12 minutes. Batch jobs parallelize across workers for further speedups.
Why is the MP3 louder or quieter than the AIFF source?
+
No automatic gain change happens unless you enable the normalize option. If you observe a level change, your audio player or media library is likely applying ReplayGain or per-track normalization on playback — not us. Disable that to hear the true MP3 levels.
Can I convert AIFF downloads from streaming services to MP3?
+
If the AIFF download is unprotected (no DRM), yes. DRM-encrypted streams (Spotify, Apple Music tracks) are encrypted at the bit level and we cannot process them. Bandcamp, SoundCloud downloads, personal recordings, and podcast files convert cleanly.
