Read, write, or remove tags from your audio files
Drop audio files to get started
MP3 · FLAC · M4A · WAV · OGG · OPUS — up to 500 MB each
Every MP3, FLAC or M4A can carry hidden tags — artist, album, title, genre, year, cover art and copyright — that travel with the file. ExifInjector is an audio metadata editor that lets you inspect, edit and strip ID3 and Vorbis tags in bulk, then verify the result.
Update title, artist, album, album artist, track number and disc number.
Fix genre, year, comment, composer, publisher and remixer fields.
Replace cover art, lyrics, BPM, copyright and custom TXXX frames.
Correct album name, compilation flag, disc and track totals.
Remove all ID3/Vorbis tags in one click for anonymous sharing.
Read hidden tags with the Media Inspector before you save.
Audio metadata (often called tags) stores information about a recording inside the file itself. It is distinct from the audio waveform — remove it and the sound is untouched, only the descriptive fields disappear.
Frames TIT2 (title), TPE1 (artist), TALB (album), TYER, TCON, APIC (cover) and TXXX (custom) — up to 80+ frames per file.
Key-value comments ARTIST, ALBUM, TITLE, DATE, GENRE, COMMENT and METADATA_BLOCK_PICTURE for cover.
iTunes atoms ©nam, ©ART, ©alb, ©day, ©gen, covr and ----:com.apple.iTunes custom data.
WAV INFO chunks, AIFF chunks and WMA tags — editable via ExifTool where supported.
Embedded JPEG/PNG cover (APIC/covr) and USLT/SYLT lyrics — often the largest metadata payload and a common privacy leak.
TCOP/©cpy, TPUB, TOWN, encoding settings and encoder string — useful for cataloging but also fingerprintable.
Tip: open the original in Media Inspector to see what ExifInjector can edit and what it will preserve.
ExifInjector reads and writes the families that matter for music libraries, podcasts and distribution. Availability depends on the container (MP3 supports the most frames; WAV the fewest).
| Tag family | Typical fields | Formats |
|---|---|---|
| Title / Artist | TIT2, TPE1, TPE2, TCOM, TEXT, TALB, TRCK, TPOS | MP3 · FLAC · M4A |
| Genre & Date | TCON (genre), TYER/TDRC (year), TDAT, TIME, release time | MP3 · FLAC · M4A |
| Cover Art | APIC (ID3), METADATA_BLOCK_PICTURE (FLAC), covr (MP4) — JPEG/PNG up to 50 MB | All audio |
| Lyrics & BPM | USLT/SYLT (lyrics), TBPM (BPM), TKEY, TLEN, TMED | MP3 · FLAC |
| Copyright | TCOP, TOWN, TPUB, WCOM, WCOP — publisher and terms | MP3 · M4A |
| Comment | COMM (ID3), COMMENT (Vorbis), ©cmt (MP4) — free text | All audio |
| Custom / TXXX | TXXX frames, ----:com.apple.iTunes, Vorbis USER comments — any key/value | Power users |
| Encoder | TENC, TSSE, ENCODEDBY, ENCODER — software and settings | All audio |
Tag names shown are the underlying ExifTool / spec identifiers. The editor shows them as human labels (Title, Artist, Album, etc.).
Drag MP3, FLAC, WAV, M4A, AAC or OGG — up to 50 files, 50 MB each.
ExifInjector reads ID3/Vorbis tags and shows current title, artist, album, genre and cover.
Type new values, replace cover art, or use a template for the whole batch.
Review the change list per file — added, modified and removed tags highlighted.
Download the edited file. Audio waveform untouched — only tags written.
Bulk templates save hours
Create a template (e.g. Artist=Your Label, Genre=Podcast, Year=2026) and apply it to 50 files in one click. Per-file overrides still possible.
Correct misspelled artist names, inconsistent album titles and wrong track numbers so players and car stereos group correctly.
Set ISRC, publisher, copyright and explicit flag exactly as distributors (Spotify, Apple Music, distributors) require.
Strip encoder, purchase info, private frames and embedded personal art before sending a demo or sample pack.
Batch-set album to show name, genre to Podcast, year and cover so Apple Podcasts and chapter markers display correctly.
Swap a 5 MB scanned cover for a 500 KB optimized JPEG — smaller files, proper aspect ratio, no embedded personal photos.
Normalize year, add comment = source, and write consistent TXXX:CATALOG for long-term searchable archives.
Manual field-by-field editing. You set each tag value directly — ideal for libraries, podcasts and catalog fixes. Uses ExifTool write.
Use when you know the exact values.
AI-assisted bulk generation from filename, folder or prompt — fills missing title/artist/genre automatically.
Use to populate a new batch quickly.
Strips all ID3/Vorbis tags in one click — anonymous files with no title, artist or cover.
Use before sharing a private recording.
Workflow: Media Inspector → Editor (manual) or Injector (AI) → Remover if you need a clean copy.
Read and write where the container supports it. Strip works on all listed formats.
Apply your template or per-file edits and download. Audio is not re-encoded.
Re-open the saved file in the Inspector — confirm title, artist and cover match your edits, stripped fields gone.
Before
TIT2: Untitled · TPE1: Unknown Artist · TALB: (empty) · APIC: 4.2 MB scan · TENC: Lavf60.3
After (edited)
TIT2: Midnight City · TPE1: M83 · TALB: Hurry Up, We're Dreaming · APIC: 420 KB JPEG · TENC: ExifInjector
ExifInjector delegates tag read/write to ExifTool by Phil Harvey — the reference implementation for ID3, Vorbis and MP4 atoms. That means frame IDs, encodings (UTF-8/UTF-16), APIC picture types and iTunes atoms are written to spec, not as a best-effort blob.
TIT2/TPE1/TALB with proper text encoding, APIC with MIME and picture type 3 (front cover).
One template applied to 50 files; per-file overrides without re-upload.
ID3 padding reused where possible; audio frames never touched or re-encoded.
No. Only the tag container (ID3/Vorbis/MP4 atoms) is rewritten. The PCM/MP3/FLAC audio frames stay byte-identical — no quality loss, no duration change.
Yes. Clear the APIC/covr field before saving. Other tags (title, artist) are preserved unless you clear them too.
For local files, yes — players read the tags directly. For streaming catalog tracks, the distributor must re-deliver the file; editing a downloaded stream file does not update the platform database.
50 files per batch, 50 MB per file. Cover art is often the largest tag — replacing a 5 MB scan with a 500 KB JPEG saves significant space.
Yes — leave all fields empty or use the dedicated Metadata Remover path which issues an ExifTool strip for audio containers as well.
Where ExifTool supports it, yes — IART, INAM, IPRD and related INFO fields are readable and writable. Support varies by WAV variant.
Inspect, edit and save — batch templates for 50 files, audio never re-encoded.
