About the TTA format
TTA (True Audio) is a no-frills real-time lossless compressor: simple 32-bit crypto-free checksums, multi-threadable encoding and IDs at both frame and file level. It filled the lossless niche on slow connections and in Russian archive communities where FLAC arrived late.
Decoding is near-instant and lossless, so converting TTA to FLAC or MP3 costs nothing in fidelity — the audio is identical, the compatibility is finally universal.

About the MKV format
MKV (Matroska) is the open container that refuses to say no: virtually any video codec, multiple audio tracks, multiple subtitle streams, chapters, attachments and menu structure in one file. It became the de facto standard for movie rips, anime releases and personal archives precisely because nothing needs to be thrown away.
The same generosity is its compatibility risk: smart players (VLC, mpv) handle everything, but smart TVs, consoles and car systems choke on exotic codec combinations inside MKV. It is also not a streaming standard, so web delivery runs through its subset, WebM.
+ Strengths
- ✓Unlimited tracks: audio, subtitles, chapters, attachments
- ✓Open specification, no licensing
- ✓Ideal archival container — nothing is lost
! Limitations
- −Device playback is hit-or-miss outside smart players
- −Not web/streaming native

Frequently asked questions
Is this TTA to MKV 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 TTA to MKV?
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 TTA 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.
