Rotate a PDF. Fix sideways scans without uploading
A document fed into a scanner in the wrong orientation produces a PDF with sideways or upside-down pages. This page rotates every page by 90° right, 180°, or 90° left. pdf-lib applies the change to each page’s standard rotation metadata, which Acrobat, Preview, browsers, and phone viewers all recognize. Scanned IDs, leases, and signed forms remain on your device.
How it works
- Drop your sideways PDF below.
- Choose the direction from the Rotate by menu: 90° right, 180°, or 90° left.
- Download the corrected PDF. Every page is rotated by the same amount.
Frequently asked questions
Will the rotation stick in other PDF viewers?
Yes. The tool sets each page’s rotation entry in the PDF itself. The standard, spec-defined way to orient a page. Rather than applying a temporary view setting. Acrobat, macOS Preview, browsers, phones, and printers all honor it.
Can I rotate only some pages?
This tool rotates every page by the same amount, which fits the common case of a whole batch scanned in the wrong orientation. If only a few pages are wrong, a workaround is to extract those pages, rotate them, and merge them back. All three tools run locally on this site.
Does rotating reduce quality or re-render the pages?
No. Nothing is rasterized or recompressed. The page content stays exactly what it was, with only the orientation metadata changed. Text stays selectable and images keep their original resolution.
Is the file uploaded while it is rotated?
No. Rotation happens in JavaScript inside your browser; the PDF never crosses the network. Scanned documents tend to be personal. Leases, IDs, signed forms, and yours stays on your machine for the entire operation, even if you go offline after the page loads.
