Rotate and reorganize a PDF's pages

Fixing orientation and page order in a PDF

A PDF almost never comes out perfect on the first try. A batch scan turns some pages sideways or upside down, depending on how the sheet fed into the scanner. A document assembled from different pieces ends up with its sections out of order. A page that should have been left out got included by mistake. None of these problems are with the content — they're with the presentation: the right page, in the wrong orientation, or in the wrong place.

This tool handles exactly that part: you upload a PDF, fix the rotation and order of whichever pages need it, remove anything that shouldn't be there, and download the result — nothing to install, and the file never leaves your computer, because all the processing happens in your browser.

A grid with a thumbnail of every page

As soon as the PDF is uploaded, the tool shows a grid with every page in the document, each one numbered by its current position in the result. Unlike a plain numbered list, every cell here shows a real thumbnail of that page's content — useful for recognizing visually which page is which, without needing to open the original PDF side by side to check.

In documents with a lot of pages, drawing every thumbnail at once would make loading slow. That's why thumbnails are generated on demand, as you scroll: a cell is only drawn once it's near the visible area, not all at once when you upload the file. Scroll through the grid gradually on large documents and the thumbnails fill in as you go.

Rotating pages, one at a time or in bulk

Every thumbnail has two rotation buttons, one for each direction, that rotate just that page by 90 degrees — the thumbnail rotates right along with it, instantly, so you can check the result before generating anything. To fix several pages in the same orientation at once, there's also a range field above the grid: enter the pages (like "1-5" or "3,7,12"), leave it blank for all of them, and apply the rotation in one go.

One important detail: the rotation is added to whatever the page already had, not replaced. Scanned PDFs frequently already carry a built-in rotation even when they look "straight" on screen — rotating a page like that by 90° adjusts from its actual current state, instead of ignoring what was already there and possibly making the orientation worse.

Reordering and removing pages

Any thumbnail can be dragged to a different spot in the grid, which changes the page order in the final PDF. Every cell also has buttons to move the page one position left or right — built for anyone on a phone or navigating with just a keyboard, where dragging isn't a reliable option.

Removing a page doesn't delete it right away: it gets flagged and drops out of the final result's count, but stays visible in the grid, faded out, with the option to restore it at any point before you generate the PDF. If something goes wrong — a rotation applied to the wrong range, a page moved to the wrong spot — the undo button steps back one action at a time, and the reset-to-original button returns the document exactly as it was uploaded, discarding every change made up to that point.

Preserving the original content

Like the portal's other PDF tools, nothing here goes through rasterization. Reordering and removing pages uses pdf-lib's page-copying function, and rotating just adjusts a rotation value stored on the page — at no point is the content turned into an image and recompressed, so the final result keeps the same text, vector, and embedded-image quality as the original file.

What this tool doesn't do

It doesn't remove a password from a protected PDF, or bypass that kind of restriction — a protected PDF can't be opened here at all. It doesn't compress or shrink the file's size. It doesn't recognize or extract text from the pages, and it doesn't do OCR. And it doesn't edit the content of any page — no text, image, or element is changed, only the orientation and position of each page within the document.
