## Inventory

| Bucket | Files | Size |
|---|---:|---:|
| All uploads | 89,883 | 58.24 GiB |
| All images | 87,619 | 54.57 GiB |
| Generated variants | 70,268 | 11.74 GiB |
| Original images | 17,351 | 42.83 GiB |

## Estimated savings for generated variants

- Sample: 501 variant images, 320.5 MiB downloaded/optimised locally, 0 errors.
- Optimisation assumptions: JPEG quality 85 with optimize/progressive and metadata stripped; PNG lossless optimise/compress; WebP quality 82.
- Estimated saving: **2,484.3 MiB / 2.43 GiB**.
- Estimated variant reduction: **20.7%**.
- Estimated saving vs current Synergy account usage `61396M`: **4.0%**.

| Ext | Population | Current size | Est. saving | Reduction | Sample |
|---|---:|---:|---:|---:|---:|
| `.jpg` | 58,663 | 8,096.8 MiB | 2,070.0 MiB | 25.6% | 200 |
| `.png` | 6,496 | 3,339.7 MiB | 367.6 MiB | 11.0% | 120 |
| `.jpeg` | 5,087 | 584.5 MiB | 46.5 MiB | 8.0% | 120 |
| `.webp` | 22 | 1.1 MiB | 0.2 MiB | 18.0% | 22 |

## Notes

- This estimate is for generated WordPress variants only, matching the Clarendon-style optimisation audit.
- Originals are much larger here (~42.83 GiB) but carry higher archival/source risk; audit them separately before considering any destructive recompression.
- Actual savings can vary depending on final optimisation tools and quality settings used on-server.
