Rotate PDF pages

What this does to a Malaysian office document

A PDF page is an object inside the file, not an image. This tool copies the page objects into a new document and leaves their content streams exactly as they were — so text stays selectable, a scanned page keeps its resolution, and the file does not grow a second JPEG generation of itself.

• Rotation is added, not replaced. A page that already carries /Rotate 270 turned another 90° becomes 0°, which is what "turn it upright" means when the scanner wrote the wrong value. The row reports the angle that was applied and how many pages it turned.
• Deleting a page shifts the numbering. Removing page 2 of 5 gives you a 4-page file where the old page 3 is now page 2. If you need the original numbers, split first and rename afterwards.
• A number that is not a page is named, not ignored. Typing 1-2, 9 into a six-page file gives you pages 1-2 and the result line quotes 9. A typo costs you the typo, never the rest of the request — and never a page you did not ask for.
• Measured in pages, not megabytes. A bank site that caps uploads at 5 MB is really asking you to remove pages: a 300 dpi A4 scan is roughly 1–2 MB per page, so a 40-page bundle has to lose most of its pages, not be compressed.
• Password-protected files are refused by name. An encrypted PDF — including one that only carries an owner (permissions) password — cannot be opened here, and pretending otherwise would hand you a blank document. Open it in Chrome or Edge, press Ctrl+P and choose "Save as PDF", then drop that copy — you do not need to remember the password to do this.
• Filled forms keep their text. Copying pages carries a page's visible annotations but not the document's form definition, so a filled LHDN or bank form is flattened first: the answers are burned into the page instead of silently disappearing.
• Nothing leaves the tab. The file is read with pdf-lib, which runs in this page; there is no upload endpoint on this site, and the network tab stays empty apart from this site's own assets.
• Split makes a ZIP, not 40 downloads. One click, one file, one entry per page named page-01.pdf so the folder sorts in reading order. The Pages field is hidden for split, because splitting means every page.
