AC3 to TTA Converter
FileFlip converts AC3 to TTA entirely inside your browser, using 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 an AC3 file to TTA?#
- Drop your AC3 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 TTA and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the TTA file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting AC3 to TTA lose quality?#
TTA is a lossless format, so nothing further is lost here, but nothing is recovered either. Whatever the AC3 encoder already threw away is gone, and the TTA file will usually be several times larger for exactly the same content.
Is it safe to convert AC3 files online?#
Yes, because nothing is uploaded. FileFlip converts AC3 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 AC3 to TTA actually does to the file#
Converting AC3 to TTA runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, writes a lossless file that cannot recover what the source already discarded, and drops encoded streams.

What is an AC3 file?#
An AC3 file holds a Dolby Digital bitstream, the compressed multi-channel audio format Dolby Laboratories introduced in 1991 for cinema and later carried onto DVD, Blu-ray discs, and digital television broadcasts.
Keep audio as AC3 when it is a DVD, Blu-ray, or broadcast track destined for a home theater receiver that decodes Dolby Digital natively.
Convert AC3 to AAC, MP3, or WAV when the audio needs to play on a phone, a laptop, or in a web page, none of which decode Dolby Digital on their own.
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.
AC3 to TTA questions people ask#
What creates an AC3 file?
An AC3 file is almost always extracted from a DVD, a Blu-ray disc, or a digital TV broadcast, all of which store their surround-sound track as a Dolby Digital bitstream. Ripping software and video editors pull that track out as a standalone .ac3 file when they separate audio from video.
What can still play an AC3 file?
AC3 plays natively in VLC and mpv on any desktop operating system, and in AV receivers that accept S/PDIF or HDMI passthrough. Windows Media Player and most phone audio apps cannot decode it without an added codec, since AC3 was built for home theater equipment rather than general music playback.
What should I convert an AC3 file to?
Convert AC3 to AAC or MP3 for playback on phones and in browsers, or to WAV if the audio needs to be edited. The Dolby Digital format is lossy, so nothing is regained by converting to a lossless format afterward; pick the target based on where the file needs to play, not on preserving quality that already had to be discarded.
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.
