rotate pdf
A flatbed scan often turns a few pages sideways when the paper goes in at the wrong orientation, and a sheet-fed scanner sometimes mixes portrait and landscape pages within the same batch. Rotating each page individually with a button on its thumbnail, or selecting several wrong pages at once and rotating them all together, fixes both cases without rescanning or reprinting anything.
No need to rescan the whole document, or touch the other 19 pages that were already correct.
A bulk selection avoids clicking the individual rotate button 12 separate times.
No. Reading, assembling, rotating and splitting the PDFs all happens entirely in your browser, using pdf.js to render the thumbnails and pdf-lib to assemble the output files. No byte of the content is ever sent to a server, which is also why the tool can work with password-protected PDFs without asking anyone but you for the password.
No. Rotation is stored as a page orientation attribute, the same mechanism any PDF reader uses to display it correctly, without re-rendering or re-compressing the page's content.
Yes, rotating a page goes onto the same undo stack as any other workbench action, so the undo button reverses the rotation exactly the way it would reverse a deletion or a reorder.

All processing happens in your browser: the loaded PDFs, the thumbnails and the assembled output files are never sent to a server. Closing or reloading the tab discards the workbench.
