Remove blank, wrong or private pages from a PDF. Nothing is uploaded.
You cannot delete every page. Password-protected PDFs must be unlocked first. The original file is never changed; you get a new copy. To keep only some pages instead, use split PDF; to join files afterwards, use merge PDF.
Is my PDF uploaded? No. Pages are removed locally in your browser.
Can I undo a deletion? The download is a new file, so your original stays untouched. Keep it until you have checked the result.
Does deleting pages reduce file size? Usually yes, but shared fonts and images may remain, so the saving can be smaller than expected. If size matters, try compress PDF.
