How to Rotate PDF Pages Online — Fix Orientation Instantly
Scanned documents frequently come through with the wrong orientation — a page rotated 90 or 180 degrees is unreadable without correction. Rotating a PDF fixes the page orientation permanently in the file, so it opens correctly in any PDF viewer on any device, without requiring the reader to tilt their screen or use a viewer that doesn't support rotation memory.
Rotate individual pages or the whole document
The tool lets you apply rotation to all pages at once or select specific pages to rotate independently. This is important when scanning produces a mixed document — most pages are portrait, but a landscape table was inserted sideways. You can rotate only that one page to landscape and leave the rest unchanged.
Rotation angles: 90°, 180°, 270°
90° clockwise — corrects a page scanned in landscape orientation. 90° counter-clockwise — corrects a page scanned facing right. 180° — corrects an upside-down page. The rotation is stored in the PDF's page dictionary, so every viewer will display it correctly — not just the one where you set the preference.
How it works under the hood
This tool uses PDF-lib to modify the rotation value in each page's dictionary. This is a metadata-level change — no content is re-rendered or re-encoded. Vector text, embedded fonts, images, and annotations remain at full quality. The file is processed entirely in your browser; nothing is uploaded.
Common scenarios requiring PDF rotation
Scanned contracts where the second page is upside down. Bank statements where the table page was fed sideways through the scanner. Architectural drawings in landscape inserted into a portrait report. Phone-photographed documents processed by a scanning app that picked the wrong orientation.

After correcting orientation, you may need to merge with other PDFs, or compress the file before sharing. To reorder pages as well, use the PDF page organiser. To convert individual pages to images, use PDF to JPG.
