DTS to ALAC Converter
Processing entirely on your device — large files may take a moment.
Convert ALAC to FLAC for non-Apple players, or MP3 for sharing. If your files are still in DTS format, this page is the shortcut: DTS is the competitor surround format to Dolby Digital, common on Blu-ray discs and remuxed movie files.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the DTS format
DTS is Dolby Digital's rival: the other surround format licensed for DVDs and Blu-rays, running at higher bitrates (up to 1.5 Mbps core) for a fuller soundstage. Movie rips and remuxes frequently carry DTS tracks, which is why so many files quietly refuse to play on phones.
Conversion to MP3 or WAV is the way out. Editors will thank you for the WAV; headphones-and-commute listeners will never hear the difference MP3 makes at reasonable bitrates.
+ Strengths
- ✓High-bitrate surround on Blu-ray sources
- ✓Widely present in movie files
! Limitations
- −Mobile/web playback almost nonexistent
- −Large compared to lossy stereo
About the ALAC format
ALAC (Apple Lossless Audio Codec) is Apple's FLAC equivalent: bit-exact lossless compression inside an MP4 container, opened-source in 2011 and now native on every Apple device and most server-side pipelines. It is what iTunes Store sells as "lossless" and what iPhone recordings encode to by default.
For non-Apple players FLAC is the safer target, and conversion is sample-exact in both directions — the decode is handled by ffmpeg's native ALAC decoder without any Apple runtime.
+ Strengths
- ✓Native on every Apple device
- ✓Open source since 2011
- ✓Reasonable sizes inside MP4
! Limitations
- −Outside Apple ecosystems FLAC wins
- −Slightly worse ratios than FLAC
- −Confusing .m4a extension doubles as lossy
Why convert DTS to ALAC?
Converting makes sense where the strengths of ALAC meet what DTS cannot give you. Native on every Apple device Meanwhile Mobile/web playback almost nonexistent One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this DTS to ALAC converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for DTS to ALAC?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Will converting DTS to ALAC reduce audio quality?
If ALAC is lossless, the output contains everything the DTS file contains — no further loss is added. If ALAC is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
