DTS to AC3 Conversion FAQ
Is DTS to AC3 a lossy or lossless conversion?
+
If both DTS 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.
Can I convert a stereo DTS to mono AC3?
+
Yes — toggle the 'force mono' option. This is useful for podcasts and voice memos to roughly halve file size.
Can I batch-convert DTS files to AC3?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the DTS to AC3 converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Does the converter remove DRM from DTS files?
+
No. PDF.to does not attempt to remove DRM. Conversions only succeed on unprotected source files.
Are my DTS files private during conversion?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded DTS and the resulting AC3 are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
