Free online DFF to AIFF converter

Source format: DFF

DFF is a DSD audio container format used mainly for high-resolution music files. It is associated with Sony/Philips DSD workflows and is commonly found in audiophile libraries, SACD rips, and archival audio collections. DFF files can store very high-quality audio, but support is limited in many everyday players and editors.

Target format: AIFF

AIFF is an uncompressed PCM audio format developed by Apple. It is widely supported by audio editors, DAWs, and media players, especially on macOS. AIFF is a good choice when you need a lossless, editable file that works reliably in professional audio software.

How to convert DFF to AIFF

The most practical way to convert DFF to AIFF is with a desktop audio tool that supports DSD input and PCM export. A common choice is foobar2000 with the appropriate DSD/decoder components, or Audacity if your DFF file is already readable through an installed import plugin. For batch conversion and better format handling, FFmpeg can also be used when built with DFF/DSD support.

1. Install a converter that can open DFF files and export AIFF.
2. Open the DFF file in the program.
3. Choose File → Export or Convert, then select AIFF as the output format.
4. Pick the desired PCM settings, such as sample rate and bit depth, if the software asks for them.
5. Start the conversion and save the resulting .aiff file.

If you prefer a command-line workflow and your FFmpeg build supports the input, a typical conversion looks like ffmpeg -i input.dff output.aiff. This is useful for batch jobs and automation.

You can also convert the file on 101convert.com for free, without installing any software.

Notes on quality and limitations

DFF is DSD-based, while AIFF is PCM-based, so this conversion is not a simple container change. The audio must be decoded and resampled from DSD to PCM, which means the result depends on the converter’s quality and settings. A good converter will preserve the sound well, but the output will not remain native DSD.

Because AIFF is uncompressed, the converted file will usually be much larger than the original DFF. Also, some DFF files contain metadata or track markers that may not transfer perfectly to AIFF, depending on the software used. For best results, use a converter that lets you control the DSD-to-PCM conversion parameters and verify the output in your target player or editor.
