What is a .LRcat file?
LRcat is the Adobe Lightroom catalog database that tracks all your photos and edits. Created by Lightroom Classic.
- Did you know
- The Lightroom catalog is actually a SQLite database under the hood.
- Lightroom edits are non-destructive: the catalogue records adjustments as text instructions rather than altering the original photos.
- The catalogue keeps its image previews separately, in a companion Previews.lrdata store of .lrprev files, each holding a pyramid of scaled renderings.
- What Analyser reads
- Identify Adobe project files and read their metadata: InDesign (INDD), XD, Animate (FLA), and Lightroom. After Effects projects (AEP, AET), Premiere Pro and Elements (PRPROJ, PREL), Photoshop (PSD, PSB) and Illustrator (AI) now open in full viewers - see After Effects, Premiere Pro, Photoshop and Illustrator.
- Depth of analysis
- .LRcat is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .LRcat file
- Drag a .LRcat file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
