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.
Typical jobs: clearing a stale copyright or publisher notice from audio you have the rights to, removing producer and composer credits from your own beats before they go out, and stripping DAW export data and tracking IDs from podcast episodes. None of this changes who owns a recording, and platforms that claim music recognise it by its sound, not its tags.
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, copyright notice (TCOP), producer and composer credits (TIPL, TCOM), 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.
FLAC and WAV: the same job in different containers
Lossless files carry the same kind of baggage in other places. A FLAC keeps text in a Vorbis comment block — including a "vendor" string naming the encoder — plus cover art in PICTURE blocks. A WAV collects chunks: LIST/INFO with software and engineer fields, Broadcast Wave `bext` with a description and coding history, `iXML` production notes, and Adobe XMP that often holds a user name and project paths.
The two modes mean the same thing in every format: listener labels stay or go, everything else goes. What a WAV sampler needs — cue points, loops, root note — is kept either way. Details per format: FLAC and WAV.
The audio is never touched
Tags sit in separate blocks from the sound: at the start and end of an MP3, in metadata blocks before the audio in a FLAC, in their own chunks in a WAV. The tool rebuilds only 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 file
Drag in an MP3, M4A, AAC, OGG, FLAC, WAV or MP4 file. You can select several at once, and mix the formats.
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?
Yes. FLAC (Vorbis comments, pictures, application blocks) and WAV (INFO, bext, iXML, XMP, embedded ID3) are cleaned the same way, with the audio copied unchanged — see FLAC and WAV. M4A and MP4 (iPhone recordings, phone videos), AAC and OGG/Opus (WhatsApp voice notes) are cleaned too: in an M4A the tag boxes are overwritten in place with empty space, so the audio does not move a byte; in an OGG the comment packet is rebuilt and every page keeps a valid checksum.
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.
Can this remove copyright notices and producer tags?
Yes, as metadata. In the default mode it strips copyright notices (TCOP), publisher info, producer credits (TIPL/IPLS), composer tags and DAW links, while keeping the track title and artist. A voice tag mixed into the audio is sound, not metadata, so it stays — and removing a notice does not change who owns the recording.
