Rotate PDF

Rotate PDF turns the pages of a PDF by 90° clockwise, 180° or 90° counter-clockwise and saves the result as a new file, without uploading it. It is for the everyday fixes: a scanned contract with pages upside down, a landscape spreadsheet that opens sideways, or one rotated photo page in the middle of a report.

Choose the file and every page appears as a thumbnail. Leave "All pages" selected to turn the whole document, or click the pages you want — the page list box fills in as you click (for example 1-3, 5), and you can also type the list yourself. The thumbnails turn on screen before you save, so you can see exactly what the result will look like.

The rotation is lossless. Every PDF page has a /Rotate setting that tells viewers to display it turned by 0, 90, 180 or 270 degrees, and this tool changes only that number. Nothing is re-rendered or recompressed: text stays selectable and searchable, and images keep every pixel. The file is re-saved, so its size can come out somewhat smaller or larger, but no page content is recompressed. The rotation is added to whatever the page already had, so a page stored at 90° and turned 90° counter-clockwise ends at 0°. Odd values that some programs write, such as -90 or 450, are first normalised to the nearest quarter turn, and a rotation a page inherits from its parent page tree is read correctly rather than ignored.

Because only that one setting changes, the rest of the document is kept as it was: bookmarks, links, fillable form fields, metadata and page sizes. One thing cannot survive any edit: a digital signature, which covers the exact bytes of the original file, will no longer validate after rotating. Password-protected and permission-locked PDFs are refused with a clear message, because the library used here cannot decrypt them; files up to 200 MB are accepted.

Rotating here changes how pages are displayed and printed in every viewer, which is different from the rotate button in a PDF reader: that usually turns only your view and is forgotten when you close the file. If you need to reorder or delete pages as well, use Organize PDF; to trim margins, use Crop PDF.

The work happens in your browser with pdf-lib (for saving) and pdf.js (for the thumbnails). Your PDF is not uploaded — you can check in your browser's developer tools, under the Network tab, that no request carries the file. The site does load its own scripts and analytics, but never your document.

1. The file's first bytes are checked for the PDF signature, then pdf-lib opens it; encrypted and damaged files are refused with a specific message. 2. pdf.js renders a small thumbnail of each page (about 240 pixels on the long side) as it scrolls into view. 3. The pages to turn are all pages, or the list you clicked or typed (numbers, ranges like 2-6, and 8- for page 8 to the end), checked against the page count. 4. For each chosen page, its current rotation — its own /Rotate or one inherited from the page tree — is normalised to 0, 90, 180 or 270, the chosen turn is added, and the result is written back as the page's own /Rotate. 5. The document is saved and offered as <name>-rotated.pdf; nothing else in the file is changed.
