How is rotation stored?

Each page carries a /Rotate value — a multiple of 90 degrees. This tool updates that value rather than re-rendering the page, so the content is simply displayed turned. Text stays selectable and the file stays small.

Can I rotate just one page?

Yes. Use the rotate arrows beneath any individual page thumbnail to turn only that page, or use the 'rotate all' buttons to spin every page together. You can mix both.

Does rotating reduce quality?

No. Because only the page's rotation metadata changes and no pixels are re-rendered, there is zero quality loss and no increase in file size from rasterisation.

No. The file is parsed and re-saved entirely in your browser with pdf-lib. The document never leaves your device.

What rotation amounts are supported?

Rotations are in 90-degree steps — 90, 180, and 270 degrees, clockwise or counter-clockwise. Each page's final angle is shown so you always know its orientation before saving.

Fix sideways and upside-down pages

Scanners and phone-camera PDFs often produce pages that are rotated the wrong way. Rather than re-scanning, you can correct the orientation in seconds. This tool reads each page, lets you turn the ones that need it, and writes a corrected PDF — all without uploading your document.

How it works

Every PDF page stores its display orientation in a /Rotate entry, which must be a multiple of 90 degrees. Viewers read that value and rotate the page content when drawing it. This tool:

Loads the PDF with pdf-lib and reads each page’s existing rotation.
Tracks the additional rotation you apply per page (the previews update live).
On save, sets each page’s /Rotate to its original angle plus your change, normalised to 0, 90, 180, or 270 degrees.

Because only this metadata value changes, nothing is rasterised — text remains selectable, vector graphics stay crisp, and the file size barely changes.

Tips and notes

Rotate all, then fine-tune. If most pages need the same turn, use the “rotate all” buttons first, then adjust the odd page out.
Clockwise vs counter-clockwise: the two single-page arrows turn that page in each direction; the displayed angle confirms the result.
No quality loss: unlike tools that flatten pages to images, metadata rotation keeps your PDF fully searchable and lightweight.
Everything is processed locally, so confidential documents stay on your machine.
