Drop MP3 files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Save the TTA, or download everything as one ZIP if you converted several files.
The MP3 to TTA converter is part of this page and runs inside your browser. Your audio files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
MP3 is lossy, so editing or re-saving it repeatedly degrades the sound. TTA stores audio losslessly in a smaller file than WAV. MP3 is at home in music and podcasts that must play anywhere; TTA is the usual choice for archiving CDs without losing quality. TTA cannot bring back detail that MP3 compression already removed; it simply stores the result without further loss, in a larger file.
The defaults suit most files. Under Options you can trim the start and end.
This pair uses the compatibility engine, ffmpeg built for the browser, because TTA cannot be written by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.
MP3 is the audio format everything plays. It shrinks audio to roughly a tenth of its uncompressed size by discarding sound most listeners cannot hear. Newer codecs are more efficient, but nothing matches its compatibility.

MP3 converterTTA is a free lossless audio codec in the same family of purpose as FLAC. It makes files noticeably smaller than WAV and rebuilds the original exactly, but few devices and apps support it.

No. The MP3 to TTA conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
No further quality is lost: TTA stores the decoded audio exactly. It cannot restore what MP3 compression already discarded, and the file will be larger.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the MP3 file, press Convert and save the TTA. There is nothing to install.
Yes. MP3 to TTA runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
