Rotate PDF
Fixes the whole document in one pass — the usual case when a scanner fed a stack in sideways. Rotation is written as page metadata, so no page is re-rendered and nothing is re-compressed.
Rotation is stored as page metadata, so nothing is re-rendered and no quality is lost. Leave the page field blank to turn the whole document.
The file is loaded in the browser; nothing is uploaded.
90 degrees clockwise, 180, or 90 anticlockwise. The angle is added to whatever rotation each page already carried.
Leave the range blank to turn the whole document, or type something like 2-5, 9 to straighten only the sheets that came in sideways.
The result opens the right way up in any PDF reader.
A PDF page carries a rotation value that readers apply when displaying it. Changing that value leaves the page content completely untouched — no re-rendering, no re-compression, no quality loss, and the file size barely moves.
The angle you pick is added to each page's existing rotation rather than replacing it. A page already stored at 90 degrees, rotated by another 90, ends up at 180 — which is what you want when a document is a mix of orientations.
Leave the range blank and every page turns by the same amount — the usual case for a stack fed into a scanner sideways. Name a range instead and only those pages move. To see thumbnails while you decide, the page organiser in the editor rotates pages one at a time.
