Upload your AIFF file and PDF.to re-encodes it into a AC3 container with sensible default bitrate and sample-rate. The AC3 download is ready in seconds.
Is AIFF to AC3 a lossy or lossless conversion?
+
If both AIFF and AC3 are lossless (WAV, FLAC, AIFF), no quality is lost. If AC3 is lossy (MP3, AAC, OGG, Opus), audio is re-encoded; we default to a high bitrate (192-320 kbps) for near-transparent quality.
What bitrate does the AC3 output use?
+
192 kbps by default for AC3 where applicable. Use the options panel to pick 96, 128, 192, 256, or 320 kbps depending on whether you want smaller files or higher fidelity.
Are tags (artist, title, album) preserved when converting AIFF to AC3?
+
Yes. ID3 / Vorbis / iTunes-style tags are mapped across formats. Album artwork is preserved when AC3 supports it.
Will sample-rate and bit-depth survive the AIFF to AC3 conversion?
+
Да, подразум› ијевано. Не смањујемо узорак или раздвајање осим ако је не тражите у панелу опција. За глас можете изабрати у 22 kHz моно да смањите величину фајла.
Can I convert a stereo AIFF to mono AC3?
+
Да — укључите опцију „ Форце моно “. Корисно је за подемисије и говорне дописе да приближно пола величине фајла.
Does PDF.to support multi-channel (5.1, 7.1) AIFF files?
+
Yes for AC3 formats that support multi-channel (AC3, FLAC, Opus). For stereo-only targets, multi-channel audio is downmixed using a perceptually weighted mix.
Can I batch-convert AIFF files to AC3?
+
Yes. Drop a whole folder of AIFF files; each becomes a separate AC3 and all are zipped for download.
Is the AIFF to AC3 converter free?
+
Yes, within the free size limit. PRO unlocks much larger files, parallel jobs, and higher bitrates.
Does the converter remove DRM from AIFF files?
+
Број PDF.to не покушава да уклони ДРМ. Претварање успева само на незаштићеним изворним фајловима.
Will the AC3 I download play on iPhone, Android, and desktop?
+
Yes. AC3 is supported natively across all major platforms or via universally available codecs. We default to the most-compatible AC3 profile.
Are my AIFF files private during conversion?
+
Yes. Uploads are encrypted in transit, the conversion runs in an isolated worker, and both the AIFF and AC3 files are deleted within an hour.
