TTA to OGA Converter
FileFlip converts TTA to OGA entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a TTA file to OGA?#
- Drop your TTA file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to OGA and the conversion starts on its own. FileFlip usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, then runs WebCodecs and FFmpeg on your own machine.
- Save the OGA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting TTA to OGA lose quality?#
Sometimes. When the codecs inside the TTA file are ones the OGA container can hold, the streams are copied straight across and nothing at all is lost. When they are not, the file has to be decoded and encoded again, and that step does cost a little quality.
Is it safe to convert TTA files online?#
Yes, because nothing is uploaded. FileFlip converts TTA files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What TTA to OGA actually does to the file#
Converting TTA to OGA runs on WebCodecs and FFmpeg, usually downloads nothing, falling back to 30.8 MB of WebAssembly if your browser cannot encode these codecs itself, copies the streams through when the codecs fit and re-encodes when they do not.
| Engine | WebCodecs and FFmpeg |
|---|---|
| Conversion path | One step: TTA → OGA |
| Downloaded to your browser | Nothing in most browsers, or 30.8 MB if yours cannot encode these codecs itself |
| Quality | Lossless when the codecs fit, lossy when they do not |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Encoded streams | Sometimes | Survives for some files and not others. |
Worth knowing before you start:
- whether the browser can do this without FFmpeg depends on the codecs it exposes through WebCodecs
- the encoded streams are copied when the file's codecs fit the target container, and re-encoded when they do not
What is a TTA file?#
A TTA file holds audio compressed with True Audio, a lossless codec built by Aleksander Djuric around real-time hardware encoding, so it decodes with very little CPU overhead compared to other lossless formats.
There is little reason to choose TTA over FLAC for a new lossless rip today; it mainly persists in existing archives and on older hardware players that already support it.
Convert TTA to FLAC for playback on current phones, players, and software, since FLAC covers the same lossless ground with far wider support.
What is an OGA file?#
An OGA file is the same Ogg container as an OGG file, but under Xiph.Org's extension convention it marks audio using any codec, Vorbis, Opus, FLAC or Speex, rather than being reserved for Vorbis specifically.
Use OGA when you need an extension that correctly signals "Ogg audio" without asserting the file is specifically Vorbis.
Convert OGA to a single-codec format like MP3 or FLAC when a destination app infers the codec from the extension, since many tools still assume .oga could hold anything.
TTA to OGA questions people ask#
What creates a TTA file?
TTA files come from ripping or archiving software that specifically chose the True Audio codec, most often foobar2000 or other Windows-based lossless ripping tools, and from a handful of portable media players that supported TTA natively before FLAC decoding became cheap enough for their hardware.
What still plays TTA files?
foobar2000 plays TTA natively on Windows, and VLC decodes it on any platform. Support outside those tools is thin; most phones and streaming apps have never supported the format.
Should I convert TTA to FLAC?
Convert TTA to FLAC when the file needs to play on a device or app that does not recognize True Audio, which in practice is most modern software. Both are lossless codecs, so the converted file reproduces the exact original audio with nothing discarded.
What's the difference between OGG and OGA?
OGA and OGG are the exact same Ogg container format; only the extension differs. Xiph.Org's convention, in use since 2007, reserves .ogg for Vorbis-encoded audio specifically and uses .oga for Ogg audio that could be any codec, including FLAC or Opus, so an .oga file makes no promise about which codec is inside.
