pdf-cleaner

PDF Cleaner is a small desktop tool that scans a PDF file for duplicate pages and blank pages, then removes them automatically, producing a cleaner version of the same document. Everything happens entirely on your own computer: the README states plainly that your files never leave your machine and no internet connection is required, which the project pitches as a meaningful advantage for anyone handling sensitive legal or financial paperwork that they would rather not upload to an online service.

The underlying approach is straightforward: the tool hashes each page's content to detect exact duplicates, and separately checks for pages that are effectively empty, then strips both kinds of pages out while leaving the rest of the document, including its original quality, untouched. Using it is described as a three step process: pick a PDF file, click a button, and receive the cleaned result back in seconds, with no configuration screens or advanced options to work through first.

The project is free and open source, aimed at anyone who wants a quick, private way to tidy up scanned or exported PDFs full of accidental blank pages or repeated scans, without paying for or trusting a browser based PDF utility. The README does not describe the programming runtime needed to launch the tool or list any installation steps beyond downloading it, and it does not go into detail on exactly how large a file it can process or how it behaves on more unusual PDF structures, so those specifics are left unstated. The author does note that if you find the tool useful, tips are welcome, though using it does not require paying anything.
