What's actually eating
your file size?

After weeks of modeling, your .blend file is 300 MB and Blender takes ages to load. Somewhere inside there are unused textures, orphan data blocks, 8K images you forgot about, and meshes with millions of vertices hiding behind modifiers.

One click. Full diagnostic report. Actionable fixes.

Texture audit

Missing files, oversized textures, packed bloat, non-power-of-2 resolutions, and duplicates โ€” all flagged by severity.

your file needs

01

File Overview

Instant snapshot of your .blend file: size, object counts, health indicator (green/yellow/red), and estimated savings from cleanup.

Frequently asked questions

Does the inspection modify my file?
No. The inspection is completely read-only. The only actions that modify data are the explicit fix buttons (Purge, Fix Transforms, Fix Unused Slots), and each requires a deliberate click.
How accurate are the VRAM estimates?
They show uncompressed GPU memory (width x height x channels x bit depth). Actual VRAM depends on your GPU driver and render engine, but the estimates are reliable for comparing relative impact.
Can I undo after purging unused data?
Yes, Ctrl+Z works immediately after purging. However, once you save the file after purging, the removed data is gone permanently.
Does it work with linked libraries?
The analysis covers local data only. Linked library data blocks are excluded from the report since they're managed by their source files.
How long does the inspection take?
Under 1 second for most files. Very heavy scenes (1000+ objects with complex modifier stacks) may take a few seconds for the evaluated mesh analysis.
Can I customize the warning thresholds?
Yes. In Preferences > Add-ons > Blend Inspector, you can set file size warning/critical thresholds, max texture resolution, packed image size limits, and toggle individual scene health checks.
