Convert LRLIBRARY to LRCAT

QUICK ANSWER
Is it possible to convert LRLIBRARY to LRCAT?
Yes - LRLIBRARY converts to LRCAT.

There is no tool that opens a .lrlibrary and saves it as a .lrcat directly. In practice you enable cloud sync inside a Lightroom Classic catalog (or run the migration workflow) so Classic downloads the cloud images and edits into its own .lrcat. The main caveat is that only synced, cloud-stored photos and their non-destructive edits come across, not the local cache structure of the .lrlibrary package.

Why convert LRLIBRARY to LRCAT?

People end up with a .lrlibrary because it is the library the cloud-based Adobe Lightroom (formerly Lightroom CC) builds in the Pictures folder, while everything in the Classic ecosystem - folder-based organization, plugins, print/book modules - runs on a .lrcat catalog. Moving from the cloud app to Lightroom Classic means getting those photos and edits into a .lrcat.

How to convert LRLIBRARY to LRCAT

Sync into a Lightroom Classic catalog EASIEST

In Lightroom Classic click the identity plate and turn on Sync with Lightroom. Classic downloads every image and edit stored in your cloud .lrlibrary straight into the active .lrcat; set the download location in Preferences.

Adobe migration workflow (Lightroom Classic)

Use Adobe's documented Classic-to-cloud and cloud-to-Classic migration so albums map to collections and edits are preserved. The synced cloud library is written into a fresh .lrcat catalog folder.

Import From Another Catalog

If you already have a Classic .lrcat exported from the cloud data, open your master catalog and choose File > Import from Another Catalog to merge those photos and edits into one .lrcat.

Quality & what to watch

  • The .lrlibrary is a cloud cache, not a catalog - photos live in Adobe's cloud, so you need to be signed in and let sync download them before a .lrcat is populated.
  • Only synced photos and their non-destructive develop settings transfer; local-only originals inside the package and any pending cloud uploads may be missed.
  • Collections and albums map over, but cloud-app features and the folder structure differ from Classic, so organization can shift after migration.

Frequently asked questions

Can I just rename a .lrlibrary to .lrcat?
No. A .lrlibrary is a package/cache for the cloud app and a .lrcat is an SQLite catalog for Classic; renaming produces an unreadable file. You must sync or migrate.
Do my edits survive the move?
Non-destructive develop edits and metadata sync into the .lrcat, but they stay editable rather than being baked into the images.
Where does Lightroom Classic put the downloaded photos?
By default into a package inside the catalog folder; you can change this to any normal folder under Preferences before syncing.
Will I lose my cloud library after migrating?
No - enabling sync in Classic downloads copies while the cloud .lrlibrary stays intact until you choose to remove it.
