MP3 Metadata Editor
Edit title, artist, album, year, track, genre, comment and cover art — on the server
At least one metadata field or a cover image is recommended — saving with nothing filled in just re-encodes the file with no changes. Pick an output format: MP3 is best for tag compatibility, WAV and FLAC for lossless quality.
JPEG, PNG or WebP — up to 20 MB. The image is embedded as the album cover inside the audio file.
⚠️ Please don't close or refresh this page until it's done, or you may lose the result.
💡 Uploads are chunked and resumable - the pace is set by your own network. A failed chunk retries by itself; you are only ever charged when the job actually completes.
Tags, covers and conversions in one stop
Read what's embedded, rewrite title/artist/album art, and export to another audio format without touching a desktop app.
Seven Tags, One Pass
Title, artist, album, year, track, genre and comment are rewritten in one server-side FFmpeg pass — a release or podcast gets its labels right everywhere.
Cover Art Built In
Attach or replace the album image with a JPEG, PNG or WebP — music players and libraries show the new artwork right after download.
Tags Written Into the File
The metadata is written into the audio file itself rather than kept in a database, so the correct tags travel with the file to every device.
Format converter included
The same page converts between MP3/M4A/WAV/FLAC/OGG after tagging — one upload, two chores done.
Supported tag fields by format
| Field | MP3 (ID3v2) | M4A (iTunes) | FLAC | OGG |
|---|---|---|---|---|
| Title / Artist / Album | ✓ | ✓ | ✓ | ✓ |
| Album artist / genre / year | ✓ | ✓ | ✓ | ✓ |
| Track & disc numbers | ✓ | ✓ | ✓ | partial |
| Cover art (front) | ✓ | ✓ | ✓ | ✓ |
| Lyrics (unsynced) | ✓ | ✓ | ✓ | — |
Covers accept JPG/PNG up to 2 MB and are resized to 1000×1000 max on write. The convert tab shares the same normalization rules as audio-merge (sample-rate/channel match), so tagged files survive conversion intact.
How it works

Pick an output format, click save, then listen to the result and download it. Files auto-delete in 30 minutes.
Frequently asked questions
Will editing metadata affect the audio quality?⌄
If you keep the output format the same as the input format and don't change the cover image, FFmpeg can stream-copy the audio — no re-encode, no quality loss. Changing the format or adding a cover image forces a re-encode, which is done at a high 192 kbps bitrate (essentially transparent for most listening).
Can I remove existing metadata or cover art?⌄
Fields you leave blank are not modified — the existing tag is kept. To clear a tag, write something like "None" or a space. The cover image can be replaced (upload a new one) but the current build doesn't support removing an existing cover — that's a known limitation.
What happens to my file?⌄
The upload, the cover image (if you added one) and the tagged result are deleted automatically within 30 minutes. Jobs are only reachable with your session's signed token.
Will players outside my phone show the new cover?⌄
Front-cover art written per the table above is read by every mainstream player and car head unit. Windows Explorer caches thumbnails aggressively — rename the file or clear the thumbnail cache if it looks stale.

What Is an MP3 Metadata Editor?
An MP3 metadata editor fixes the information stored inside an audio file — the title, artist, album, year, track number, genre and comment tags that music players and libraries display. Ever seen a song labeled Track 01 with no artist, or a podcast episode with someone else's album art? That is missing or wrong metadata. Musicians preparing releases, podcasters labeling episodes and anyone who wants a music library to look professional use it. This tool rewrites those tags on our servers and can attach or replace the cover image too, so the file carries the right name, the right credits and the right artwork wherever it travels.
What this tool can do
- 🏷️ Edit title, artist, album, year, track number, genre and comment
- 🖼️ Attach or replace the album cover — JPEG, PNG or WebP
- ⚡ Write tags without re-encoding when the source and target formats match
- 🔀 Export as MP3, WAV, OGG, AAC or FLAC
- ✨ Produce a file that displays correctly in every player and library
When you would use it
- Fixing a mislabeled MP3 before you share it anywhere
- Adding cover art so a music app shows the right artwork
- Tagging a podcast episode with the correct title and artist
- Preparing a demo track with proper credits before sending it out
Your audio is uploaded over an encrypted connection, tagged on our servers, and automatically deleted within 30 minutes. The technical caveat: tags and cover art are written into the file itself, and when the output format matches the source, the audio is copied through losslessly. If you choose a different output format, the audio must be re-encoded, which can slightly change the sound — so keep the format the same when you want pure tag editing.
