How do I convert WMA audio to AIFF without losing quality?
+
Upload the WMA file and our converter picks a AIFF codec / bitrate combination matched to the source. Lossless target (AIFF = WAV / FLAC / ALAC) preserves every sample; lossy target (AIFF = MP3 / AAC / OGG / Opus) defaults to 192 kbps which is transparent for most ears.
What bitrate does the AIFF file use?
+
Default 192 kbps for lossy AIFF; pass-through (no bitrate dial) for lossless AIFF. Override to 320 kbps for audiophile output, or 96 kbps for voice / podcast where smaller files matter more than fidelity at the extremes.
Will going from WMA to AIFF reduce my audio quality?
+
If WMA is lossy and AIFF is lossless (e.g. MP3 -> WAV), the AIFF file is no better than the WMA — you cannot recover information that was already thrown away. If WMA is lossless and AIFF is lossy, the AIFF codec recompresses; at 192 kbps this is transparent for most content.
Does the WMA to AIFF converter keep ID3 / metadata tags?
+
Yes — title, artist, album, year, track number, and embedded album art are read from WMA and written into the AIFF container where the AIFF format supports tags (which all common ones do).
Can I batch convert hundreds of WMA files to AIFF?
+
Yes — drop a folder of WMA files in and we process them in parallel. Pro 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 AIFF keep the same sample rate as WMA?
+
By default yes (48 kHz WMA -> 48 kHz AIFF). If you need to downsample for compatibility (e.g. 96 kHz -> 44.1 kHz for CD burning) the advanced sample-rate option handles this with a high-quality polyphase resampler.
Can I normalize loudness in the WMA to AIFF step?
+
Yes — the loudness-normalize option applies ITU-R BS.1770 / EBU R128 normalization to the AIFF output, targeting -14 LUFS (streaming standard) or -16 LUFS (podcast standard). Useful when batch-converting tracks with varying mastering levels.
Will the AIFF play on my car stereo / iPod / Sonos?
+
MP3 plays universally. AAC plays on Apple, most Android, and Sonos. FLAC plays on Sonos and modern Android, less well on older iPods. WAV plays on everything but is huge. The advanced options include device presets for these common targets.
Is my WMA file private during conversion?
+
Yes — uploaded WMA files are processed in isolated workers and deleted within minutes. We never play, store, or share audio content. See /privacy/ for the data retention window.
How long does converting a 1-hour WMA to AIFF take?
+
Same-codec re-mux: 10-30 seconds. Re-encode to a different codec: typically 10-20% of source duration, so a 1-hour WMA -> AIFF finishes in 6-12 minutes on the standard pipeline.
Why is the AIFF file louder / quieter than the WMA 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 is probably applying ReplayGain or per-track normalization on playback — not us.
Can I convert WMA downloads to AIFF?
+
If the WMA download is unprotected (no DRM), yes. DRM-encrypted streaming files (Spotify, Apple Music) are encrypted at the bit level and we cannot process them. Sources from Bandcamp, SoundCloud, and personal recordings convert fine.
