Local-first metadata editor and music organizer

Clean your music library without moving your audio.

Choose FLAC, AIFF, WAV, and MP3 files, let CrateTag clean them up with trusted metadata on this device, and come away with organized, ready-to-play files that fit your library.

Edit FLAC, AIFF, WAV, and MP3 metadata with a local-first cleanup flow that keeps source audio on this device.

What this page covers

CrateTag helps MP3-heavy visitors start quickly while keeping metadata editing, music organization, and mixed-format cleanup visible across the whole workflow.

  • Messy tags make search and sorting harder than they should be.
  • Mixed-format folders slow down repeat cleanup work.
  • Library prep gets easier when the final files come back organized.

Broad cleanup workflow

Clean metadata and organize music from the first screen.

The homepage leads with metadata editing, music organization, local-first cleanup, and mixed-format support so visitors can understand the whole workflow before choosing a specific route.

  • Metadata editing and music organization stay visible in top-level copy.
  • MP3, FLAC, WAV, and AIFF are named together.
  • MP3-focused routes connect back to the broader library cleanup workflow.

What gets cleaned

Fix the metadata that actually changes day-to-day library work.

CrateTag focuses on track identity, release context, sorting detail, filenames, and folder organization so the result is easier to trust after import.

  • Clean titles, artists, albums, artwork, BPM, key, year, and IDs.
  • Return organized filenames and folder structure.
  • Keep the local-first promise explicit throughout the flow.

Keep the workflow browser-side while metadata and artwork support stay focused.

CrateTag is built as a local-first metadata editor: source audio stays on this device, server requests focus on metadata and artwork support, and the finished ZIP stays local.

  • 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

Does CrateTag only work for MP3 files?

No. CrateTag supports MP3, FLAC, WAV, and AIFF across the broader metadata-editor and music-organizer workflow.

Does CrateTag upload my source audio to the server?

No. Source audio stays on this device. Server requests are limited to metadata and artwork support for the browser-side tagging flow.

Can I use the same workflow for mixed-format folders?

Yes. Mixed MP3, FLAC, WAV, and AIFF folders can go through one cleanup route for metadata, artwork, filenames, and organization.

Is CrateTag only for DJs?

It is useful for DJs, collectors, promo cleanup, and anyone who wants a stricter metadata editor plus music organizer for local libraries.
