How to Rotate a PDF

Rotate a PDF — one page or all pages — without re-scanning. Browser-based, free, no upload. Useful for fixing scans that came out sideways.

The most common reason to rotate a PDF: you scanned a stack of pages and a few of them came out sideways or upside down. Re-scanning is slow; rotating in software takes 10 seconds.

Use Dropvert's PDF Rotate

Open the Rotate PDF tool. Drop the file. The tool shows every page as a thumbnail.

  • Rotate one page: click the page, then click 90° / 180° / 270°.
  • Rotate all pages: click "Apply to all" with the rotation you want.
  • Mixed rotation: select multiple pages with shift-click, apply rotation only to the selection.

Click Download. The output PDF has every page with its new orientation baked in — every PDF reader will display them correctly without further user action.

This runs entirely in your browser — the file never leaves your device.

Why "rotate" sometimes looks like it didn't work

Some PDF readers display rotation metadata as a viewing hint without actually transforming the page contents. If you "rotate" a page in Preview on macOS and save, then open the same file in Adobe Reader, the page might appear rotated in one and not the other.

Dropvert's rotate operation modifies the actual page transform in the PDF, not just the viewer hint. Every reader interprets the result the same way.

Other things you can do

  • Remove pages — auto-detect blank pages from a duplex scanner that scanned a single-sided stack.
  • Merge PDFs — combine the rotated PDF with others.
  • Compress the result if the file got bigger (rotation alone shouldn't change file size, but if you re-render afterward it might).

FAQ

Does rotation lose quality? No. Rotation in PDF is a transform applied to the existing page contents — it doesn't re-rasterize anything. Even after multiple rotations, the page is bit-for-bit identical to the original (just oriented differently).

Can I rotate by an arbitrary angle (e.g., 17°)? No — PDF rotation is only 0°, 90°, 180°, or 270°. For arbitrary angles you'd need to convert each page to an image, rotate the image, and embed it back as a new PDF. That does lose quality. If your scan is slightly tilted (a few degrees), most modern scanners' "auto-deskew" feature is the right fix at scan time, not post hoc.

My PDF has 200 pages. Can I rotate them all in one click? Yes. The "Apply to all" button does exactly that — pick the rotation, apply, download.
