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 .lrprev file holding a pyramid of scaled renderings.
- What Analyser reads
- Identify Adobe project files and read their metadata: Photoshop (PSD, PSB), Illustrator (AI), InDesign (INDD), After Effects (AEP, AEPX, AET) with composition / layer / effect and asset extraction, Premiere Pro and Elements (PRPROJ, PREL) with sequence and media counts, XD, Animate (FLA), and Lightroom.
- 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.
