Rotate PDF pages

This tool fixes orientation problems that show up after scanning or merging files: a contract that imported upside down, a spreadsheet exported in landscape that needs to read as portrait, or a single inserted page that faces the wrong way in an otherwise correct document. You pick a rotation amount and choose whether it applies to the whole file or just specific pages, then download the corrected PDF.

Rotation is offered in fixed quarter turns only: 90, 180, or 270 degrees. There is no free-angle option, so this is for correcting orientation, not for nudging a slightly skewed scan back to level. If a page came in tilted by a few degrees, a quarter turn will not fix that.

Because each turn is a quarter of a circle, you can reach any of the four orientations by combining what you apply now with what is already on the page. Choose 90 to turn clockwise, 270 to turn counter-clockwise, and 180 to flip a page that is fully upside down.

When you switch the scope to custom, you type page numbers separated by commas, or ranges with a hyphen, such as 1, 3, 5-7. The tool reads this list and rotates only those pages. Single pages and ranges can be mixed in the same entry.

Be precise here, because the parsing is strict. If any number falls outside the document's page count, or the text cannot be read as page numbers and ranges, the tool stops and tells you which pages the document has instead of guessing. Commas, spaces and any kind of dash all work, so '1, 3-5' and '1 3–5' select the same pages.

To avoid an unwanted full-document rotation, enter only page numbers that exist in your file, double-check the range bounds, and then open the result to confirm that only the pages you intended were turned. If the whole document came out rotated when you wanted a few pages, a typo or an out-of-range number in your selection is the likely cause.

The rotation is additive. The tool reads each target page's existing rotation, adds your chosen amount, and wraps the total at 360 degrees. So applying 90 to a page already stored at 270 lands it back at 0. If a page already carries an unexpected baseline rotation, account for that when choosing your amount.

Your selection is written as the page's rotation flag rather than by redrawing the page, so the underlying content is not rasterized. Text stays selectable and searchable, images keep their quality, and the file size barely changes compared with the original.

The download link your browser creates is released automatically after about ten minutes, so save the file before then if you need it.
