Four clean-up jobs in one pass
Tick any combination of Compress, Flatten, Remove Metadata and Add Page Numbers, and they run one after another on a single PDF.
Each of these exists as its own page, and the only thing this adds is doing them together. That matters more than it sounds, because running them separately means downloading a file, finding it, uploading it to the next tool, and repeating — four times over. Here you tick what you want once and download one finished document.
