One PDF at a time. Pages are rotated without re-encoding.

Quick start

How to rotate a PDF

Rotate selected or all pages of a PDF by 90°, 180° or 270° — locally, with no quality loss.

  1. Step 1
    Drop or pick a PDF

    Drag your PDF onto the drop zone, click to choose it, or paste from the clipboard. The file stays on your device.

  2. Step 2
    Pick rotation and scope

    Choose 90°, 180° or 270° clockwise, and decide whether to rotate every page or just a specific range like 1-3,5,7-9.

  3. Step 3
    Click Rotate, then download

    Hit Rotate. The new file is built locally and offered as <name>-rotated.pdf — no signup, no upload, no server-side copy.

In-depth guide

Rotate PDF pages in your browser — full guide

This tool rotates one or more pages of a PDF document by 90°, 180° or 270° clockwise. The rotation is stored as page metadata, not by re-rendering the content, so quality is preserved exactly and file size barely changes. Everything runs locally in your browser — your PDF is never uploaded.

When to use this tool

Browser-based rotation is the right tool when:

  • You scanned pages sideways or upside-down and need to fix orientation before sharing.
  • You receive a PDF mixed with portrait and landscape pages and want every page to face the same way.
  • You're working with sensitive documents (contracts, IDs, tax records) and don't want them on a third-party server.
  • You want a quick fix without launching a full PDF editor.

Choosing the right rotation

The three rotation options are clockwise. Pick whichever takes the shortest path:

  • 90° clockwise — fix a page that looks counter-clockwise sideways (the top is on the left).
  • 180° — flip an upside-down page right-side up.
  • 270° clockwise (= 90° counter-clockwise) — fix a page that looks clockwise sideways (the top is on the right).

If your starting orientation is unpredictable, try 90° first and click Rotate again until the page lands the right way up.

Rotating only some pages

Pick Selected pages to apply the rotation to a subset of pages. Enter a comma-separated list of pages or ranges:

  • 1 — only the first page.
  • 1,3,5 — pages 1, 3 and 5.
  • 2-6 — every page from 2 to 6 inclusive.
  • 1-3,5,7-9 — mix of ranges and singletons.

Pages outside your selection are kept exactly as they were.

Privacy & safety

Nothing leaves your browser. We don't even have an upload endpoint.

Every byte of the work happens in a Web Worker on your machine. No copy of your PDF is sent anywhere, the file is dropped from memory the moment you close the tab, and nothing is logged. Open DevTools → Network while rotating: you'll see zero outbound requests for your file.

For password-protected PDFs, decrypt the file first with your PDF reader (Save as → no password) — encrypted files cannot be saved by pdf-lib.

Frequently asked questions

Is my PDF uploaded anywhere?

No. Rotation runs 100% inside your browser using a Web Worker. The file never leaves your device — open DevTools → Network while rotating to verify yourself.

Does rotating reduce the quality of my PDF?

No. This tool changes the page-rotation metadata only — page content (text, vectors, embedded images) is copied byte-for-byte, so visual quality is identical to the original.

Will rotation make the output file larger?

Output size is essentially identical to the input (within a few hundred bytes). The rotation flag is a small dictionary value — no re-rendering happens.

Can I rotate only specific pages?

Yes. Pick "Selected pages" and enter a range like 1-3,5,7-9. The chosen pages get the rotation; the rest are left untouched.

Why does the rotation 'stack' if I keep rotating?

Each rotation adds to the page's existing angle. If a page is already at 90°, a further 90° rotation lands it at 180°. The tool handles wrap-around at 360° automatically.

What about password-protected PDFs?

Decrypt the file first in your PDF reader (save a copy without a password), then rotate it. The tool can read encrypted files for the page count but cannot save rotations into them.

Will digital signatures survive rotation?

No. Any structural change to a signed PDF invalidates its signatures — rotate, then re-sign the resulting file if you need signed output.
