Audio Format Conversion

How to Convert DFF to FLAC in Batches

DFF is a DSD audio format with limited device and player support. Converting it to FLAC gives you a lossless PCM file that plays on far more hardware — and PureConvert Batcher converts entire folder trees in one run.

Why convert DFF to FLAC

A practical conversion for wider playback.

DFF files store DSD audio, which many players, phones, and car stereos cannot play. FLAC is a lossless PCM format with broad support and first-class tags and cover art. Converting a DFF library to FLAC keeps the music lossless inside the PCM world and makes every file easier to play, sync, and organize.

How to do it with PureConvert Batcher

Five steps, whole-library friendly.

  1. 1

    Pick the source folder that holds your DFF files — subfolders are scanned along with it.

  2. 2

    Pick a different target folder — it cannot be the same folder as the source.

  3. 3

    Under type filtering, select only .dff so mixed libraries convert only the files you want.

  4. 4

    Choose FLAC as the output format and a compression level, then set the sample rate (auto, 44.1, 88.2, 176.4, or 352.8 kHz) and bit depth (auto, 16, 24, or 32-bit).

  5. 5

    Start the conversion — progress shows scanned, matched, skipped, and pending counts, and the output mirrors the source folder structure with tags and covers carried over.

PureConvert Batcher is completely free — no in-app purchases, no limits on file count or runs — and all conversion happens locally on your machine. See PureConvert Batcher

FAQ

Is DFF to FLAC lossless?

No. DSD to PCM is a real conversion, not a lossless move — DSD and PCM store audio differently. The FLAC file itself stores the converted PCM losslessly. Higher sample rates keep more data and produce larger files.

Can the conversion go back to DFF or DSF?

No. DSD formats (DSF and DFF) are supported as input only; they cannot be an output.

Does it work on a whole library at once?

Yes. There is no limit on file count. Point it at the library folder and the subfolder structure is preserved in the output. Reruns skip intact same-name files at the target, so updating the converted copy later only processes what is new or broken.

Are tags and covers preserved?

Yes. Tags such as title, artist, album, and genre, plus cover art, are copied in full to the new files.
