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 MP2, or download everything as one ZIP if you converted several files.
The MP3 to MP2 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. MP2 is the audio format broadcast and DVD-authoring tools expect. MP3 is at home in music and podcasts that must play anywhere; MP2 is the usual choice for broadcast radio and television audio. Both formats are lossy, so the content is compressed a second time; start from the best copy you have.
The defaults suit most files. Under Options you can choose the bitrate and trim the start and end.
This pair uses the compatibility engine, ffmpeg built for the browser, because MP2 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. MP2 is written at 192 kbps unless you choose another bitrate.
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 converterMP2 is the older sibling of MP3. It is less efficient but simpler and robust, which is why digital radio, digital television (DVB) and Video CDs adopted it. A .mp1 file is the even simpler Layer I.
Opens in VLC, broadcast software and most desktop players; fewer phone apps

No. The MP3 to MP2 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
MP2 is a lossy format, so a small amount of detail is traded for a smaller file. At the default setting the difference is hard to notice. You can choose the bitrate under Options.
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 MP2. There is nothing to install.
Yes. MP3 to MP2 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.
