The page numbers you enter for removal are inverted by the tool to produce a keep list: every index from 1 to the total page count that is not on the remove list. That keep list is passed to pdf-lib's copyPages(), and the surviving pages are appended to a new document with addPage(). The original file on disk is untouched, you simply receive a cleaned-up copy.
All processing happens inside your browser tab. pdf-lib handles everything in memory, with no network requests. You can verify this yourselfin your browser's DevTools Network tab.
For rejoining selected pages later, try merge PDF. To export each page as an image, use PDF to image. For straightening pages before splitting, see rotate PDF.
