DTS to FLAC Converter
Processing entirely on your device — large files may take a moment.
DTS is the competitor surround format to Dolby Digital, common on Blu-ray discs and remuxed movie files. Convert to FLAC when you want a permanent, lossless archive of your music.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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 FLAC format
FLAC (Free Lossless Audio Codec, Xiph, 2001) compresses audio to roughly 50–60% of its PCM size and restores every bit on playback — a ZIP for music that also carries proper tags, hi-res support up to 32-bit/655 kHz on paper (24-bit/192 kHz in practice) and full open-source pedigree. It is the archive format of digital music collections.
Support followed maturity: every serious player, modern Android (system-level), most cars and streaming purists' devices handle FLAC natively. Apple resisted for years but iOS 11+ plays it, with the caveat that iTunes/Apple Music syncing still prefers ALAC. The price of losslessness is size — about five times MP3 at comparable quality.
+ Strengths
- ✓Bit-perfect lossless with real compression
- ✓Hi-res capable (24-bit/192 kHz)
- ✓Open, unpatented, tag-native
! Limitations
- −~5× the size of lossy formats
- −Apple syncing prefers ALAC
- −Overkill for casual listening

Frequently asked questions
Is this DTS to FLAC 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 FLAC?
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 FLAC reduce audio quality?
If FLAC is lossless, the output contains everything the DTS file contains — no further loss is added. If FLAC 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.
