Local-first music metadata cleanup for real music libraries

Clean music metadata without losing control of your files.

CrateTag Studio helps clean track titles, artists, albums, artwork, labels, genres, BPM, keys, ISRCs, release dates, filenames, and folder structure across FLAC, AIFF, WAV, and MP3 files.

Real music libraries are rarely one format. CrateTag supports MP3, FLAC, WAV, and AIFF so you can clean mixed folders without splitting the job into separate tools.

What this page covers

Choose a messy folder, review the suggested cleanup, and download a cleaner ZIP that is ready to bring back into your crate, archive, or music library.

  • Source audio stays on your device.
  • Metadata is read locally in the browser.
  • Matching support uses metadata-only requests.

What CrateTag cleans

Clean the metadata that matters after import.

CrateTag focuses on the fields music people actually depend on: the details that make tracks searchable, sortable, recognizable, and easier to trust in the next library step.

  • Track identity, artwork, release context, BPM, key, filenames, and folder structure all stay in scope.
  • Keep the output reviewable instead of pretending every file resolves perfectly.
  • Use one cleanup workflow across MP3, FLAC, WAV, and AIFF folders.

Mixed-format support

One metadata cleanup workflow for mixed music folders.

Real music libraries are rarely one format. CrateTag supports MP3, FLAC, WAV, and AIFF so you can clean mixed folders without splitting the job into separate tools.

  • Support MP3, FLAC, WAV / WAVE, and AIFF / AIFC in one route.
  • Use format-aware cleanup instead of treating every audio file like the same generic upload.
  • Mixed-format cleanup and music organization stay visible on the broad metadata-editor route.

Reviewability

Designed to protect your library from bad writes.

CrateTag stays helpful without being reckless. When a match is unclear, the workflow surfaces that ambiguity instead of pretending every file was perfectly resolved.

  • Ambiguous files are easy to review.
  • Skipped files explain what happened.
  • Strict matching protects the library instead of punishing the user.

Local-first cleanup for music files you care about.

In the main browser cleanup flow, your source audio stays on your device. CrateTag reads file metadata locally, sends metadata-only requests for matching support, then writes tags, artwork, and the final ZIP locally in the browser.

  • Audio stays on this device during cleanup.
  • Server requests are limited to metadata and artwork support.
  • Finished ZIPs stay local so you control the final files.

Common questions

What is a music metadata editor?

A music metadata editor helps clean the information stored inside music files, such as title, artist, album, artwork, genre, BPM, key, label, release date, ISRC, and other details that affect search, sorting, and library organization.

Which file formats does CrateTag support?

CrateTag supports MP3, FLAC, WAV, and AIFF in the browser cleanup workflow, with format-aware handling for mixed music folders.

Does my source audio upload to the server?

In the main browser cleanup flow, source audio stays on your device. CrateTag reads metadata locally, uses metadata-only requests for matching support, then writes tags, artwork, and the final ZIP locally in the browser.

What fields can CrateTag help clean?

CrateTag can help clean titles, artists, albums, album artists, artwork, genre, label, BPM, key, year, release date, ISRC, filenames, and folder structure.

Is this useful for DJs?

Yes. CrateTag is built for library cleanup work like crate prep, promo-folder cleanup, and preparing files before importing them into rekordbox, Traktor, Serato, Engine DJ, or another music library.

Will every file be matched perfectly?

No. A careful tool does not promise that. CrateTag is designed to be strict and reviewable, so unclear matches can be surfaced instead of silently writing bad metadata into valuable files.

What do I get at the end?

You get a cleaner, reviewable ZIP package with updated metadata, artwork, filenames, and organization ready to bring back into your library.
