Your MP3 may be naming you
An audio file is not only audio. At its head and tail it carries a block of data called an ID3 tag — you know it as the thing your music player reads the title and artist from. What is less known is that the same block usually holds rather more than that.
A typical podcast episode exported from a DAW (Audition, Reaper, Logic, Audacity) routinely carries: the name of whoever encoded it, the name and version of the software, internal comments written during production, and sometimes a unique tracking identifier added by a host. You did not put any of that there — the software did, and it all travels with the file when you publish it.
Removing every tag is the wrong answer
With a photo it is simple: there is no reason for GPS coordinates to survive. With audio it is not. Strip the title, artist and album and the file shows up in a listener’s library as "Unknown Artist" — using the tool would make your work invisible.
So there are two modes, and the default is the one that keeps what a listener sees and drops the rest:
- Kept — title, artist, album, track number, genre, year.
- Removed — encoded by (TENC), software (TSSE), comments (COMM), publisher, vendor-private data (PRIV), tracking identifier (UFID), embedded links, timestamps, cover art, and legacy ID3v1/APE tags.
If you are archiving a file or want it genuinely anonymous, "every tag" is one click away — as a deliberate choice rather than the default.
The audio is never touched
Tags sit in separate blocks at the start and end of the file; the sound itself is in the middle. The tool cuts out those blocks and copies the audio through byte for byte. There is no re-encoding, so there is no quality loss — a 320 kbps file stays 320 kbps.
That is the difference from "cleaning" a file by re-exporting it: re-exporting compresses the audio again, and degrades it a little every time.
Everything runs in your browser. You do not have to upload an unreleased episode or an unmastered track to a website; the file never leaves your device.
How to remove ID3 tags from an MP3
Step 1: Upload the MP3
Drag in your audio file. You can select several at once.
Step 2: Read what was found
The tool parses the file and lists the kinds of tags inside it — encoded by, software, comments, tracking identifiers and so on.
Step 3: Choose a mode
If you are publishing, "technical data only" is the right choice: title and artist survive. For a genuinely anonymous file, choose "every tag".
Step 4: Clean and download
A single file downloads directly, several arrive as a ZIP. Your source file stays unchanged.
Frequently Asked Questions
Does this reduce audio quality?
No. Tags live in blocks separate from the audio; the tool cuts only those blocks and copies the sound across unchanged. Because the file is never re-encoded, the bitrate and quality are preserved exactly.
Does it also remove the title and artist?
Not in the default mode — those are kept deliberately, because they are what a listener sees. Choose "every tag" if you want them gone as well.
What is actually in my podcast file?
Most commonly: the name and version of the editing software (TSSE), the name of whoever exported it (TENC), comments left during production (COMM), and on some hosting platforms a unique identifier (UFID). Dropping the file in and reading the report is quicker than guessing.
Are WAV or FLAC supported?
MP3 only for now. WAV and FLAC store metadata in entirely different structures, and we would rather keep the scope honest than pretend to support them and hand back a broken file.
Why is cover art removed?
Cover art is a photograph embedded inside the file, and it can carry metadata of its own — its own EXIF block, sometimes including where it was taken. If you are cleaning for privacy, leaving it in leaves a gap.
Is my file uploaded?
No. Reading and cleaning both happen entirely in your browser; your audio never leaves your device.
