- Yes — use the bulk compressor. Drop a folder or multi-select files; the queue processes them in order with progress per file, and you can download all results as a ZIP.
- Do my images get uploaded anywhere?
- No. The tool runs entirely in your browser — important for client work, internal assets, and anything not yet published.
