Local-first music library cleanup for mixed-format collections

Make your music library easier to trust.

CrateTag Studio helps clean messy metadata, artwork, filenames, and folder structure across FLAC, AIFF, WAV, and MP3 files — so your library is easier to search, sort, import, and maintain.

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

What this page covers

Choose the folder that needs attention, 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.

Library maintenance

Manage the cleanup details that shape the whole library.

CrateTag is not trying to replace your DJ software or music player. It helps prepare cleaner files before they go back into the tools and folders you already use.

  • Clean metadata, artwork, filenames, and folder output in one workflow.
  • Keep the broader library-maintenance framing visible, not just one-file tag editing.
  • Support DJs, collectors, archivists, labels, and technical users with the same local-first boundary.

Repeatable cleanup

A repeatable cleanup pass for the folders that pile up.

Start with promos, old downloads, archive folders, or exports, review the suggested cleanup, and bring a cleaner ZIP back into the library after the pass is done.

  • Use the workflow for recurring maintenance, not just one-off rescue jobs.
  • Keep reviewable output visible before files go back into the library.
  • Tie better metadata and filenames to a more trustworthy collection over time.

Reviewability

Helpful cleanup without reckless writes.

CrateTag stays careful. 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.

A local-first cleanup workflow for 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

Is CrateTag a full music library manager?

CrateTag helps manage the cleanup side of your library: metadata, artwork, filenames, folder output, and reviewable ZIP packages. It is not a playback app, streaming service, or replacement for DJ/library software.

Which formats does CrateTag support?

CrateTag supports MP3, FLAC, WAV, and AIFF in mixed-format cleanup workflows.

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.

Is this useful for DJs?

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