How to Rotate PDF Pages

Scanned documents often arrive sideways or upside-down — rotating PDF pages fixes their orientation for proper reading. The rotation can be applied to specific pages or all pages, in 90-degree increments. The change is metadata only, not destructive — quality is preserved exactly.

Step-by-step instructions

  1. 1

    Know what the browser can do today

    FormatDrop cannot rotate a PDF yet. A dedicated rotate tool — page thumbnails, per-page selection, and 90°, 180°, or 270° turns — is coming soon. Today FormatDrop's PDF pages convert to and from PDF, for example PDF to JPG or photos to PDF, fully in your browser. Free plan: up to 5 files at a time, 10 MB each. Pro raises the cap to 500 MB per file.

  2. 2

    Rotate the PDF with a tool you already have

    On a Mac, open the PDF in Preview, show thumbnails, select the pages, then use Tools → Rotate Left or Rotate Right, and save. On Windows or Linux, the free command-line tool qpdf rotates all pages or a page range in one command — the exact commands are in the FAQ below. Rotation is a metadata change, so quality is not touched.

  3. 3

    Check the result, then convert if you need to

    Open the saved PDF and confirm every page reads upright. If you also need the pages as images, or need images combined into a PDF, FormatDrop's PDF converter does that part in your browser today — files never leave your device.

Why rotate a PDF?

Scanned PDFs arrive in random orientations; rotation fixes them with no quality loss. It's a routine fix that takes seconds with the right tools.

Your files never leave your device

FormatDrop runs the conversion engine entirely inside your browser using WebAssembly. No file upload. No server. Nothing stored. You can verify this by opening DevTools → Network tab and watching: zero upload requests.

Frequently asked questions

Command-line tool to rotate PDF?
qpdf: `qpdf --rotate=90 input.pdf output.pdf` rotates all pages 90° clockwise. For specific pages: `qpdf --rotate=90:1-5 input.pdf output.pdf` rotates pages 1–5. PDFtk: `pdftk input.pdf rotate 1-endeast output output.pdf`.
Will rotating affect file size?
Negligibly — rotation is a metadata operation. The file might grow by a few bytes due to qpdf's rewriting. Image and text content remain bit-identical.
How do I rotate PDF on Mac?
Preview: open the PDF, View → Thumbnails, select the pages, Tools → Rotate Left/Right. File → Save (or Save As to keep the original).
