BucketLeanSafely shrink JPEGs in your Cloudflare R2 bucket

Self-hosted scans, verified originals, durable jobs, and a documented HTTP API.

Get started

Use the API

Discover before writing

Scan a bucket or prefix, inspect eligible JPEGs, and then create a job.

Keep a verified original

Every replacement requires a checked backup and independently readable restore manifest.

Recover uncertain work

SQLite persists retries and upload intent so the worker can reconcile state after a failure or restart.

The dashboard and API are served by the same application. This documentation site builds to static HTML and can be hosted separately; it does not contain or expose your R2 credentials.
