Processing entirely on your device — large files may take a moment.
DTS Surround Audio and Dolby Digital Plus (E-AC3) exist for different jobs: DTS is the competitor surround format to Dolby Digital, common on Blu-ray discs and remuxed movie files. Convert audio to E-AC3 for streaming-TV authoring, or E-AC3 tracks to MP3/WAV for editing.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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 E-AC3 format
E-AC3 (Dolby Digital Plus) is the streaming-generation successor of the classic AC3: better audio at roughly half the bitrate, support for up to 15.1 channels, and the mandatory audio codec of UHD Blu-ray and most streaming-TV platforms. Netflix, Amazon and broadcast IPTV all ship it.
For authoring streaming deliverables, E-AC3 at 192-384 kbps is the safe standard. For editing or everyday playback, convert it to WAV/MP3 first — few audio editors accept it natively.
+Strengths
- ✓Better quality than AC3 at half the bitrate
- ✓The streaming-TV and UHD Blu-ray standard
- ✓Up to 15.1 surround channels
!Limitations
- −Poor editor/playback support outside TV pipelines
- −Lossy — not for archival masters

Frequently asked questions
Is this DTS to E-AC3 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 E-AC3?
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.
Can I convert a whole folder of DTS files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
