No sign-up. No upload. Nothing to install.

How to rotate pages in a PDF

  1. Open the PDF. Drop your document onto PDFLight.
  2. Pick the pages. Tick the pages you want in the sidebar, or switch to grid view to see them all at once. Ctrl+A selects everything.
  3. Rotate. Click Rotate. Click again to keep turning by 90°.
  4. Save. Click Save. The rotation is written into the file itself — it is not just a display setting.

A rotation that actually sticks

Most PDF readers let you rotate the view, but the change is lost the moment you close the file — it was never written to disk. PDFLight rebuilds the document with the new page orientation, so the rotation survives being emailed, printed or opened anywhere else.

This is the usual fix for scans and phone photos converted to PDF, where half the pages come out on their side. It is also worth doing before OCR: recognition engines expect roughly upright text, and a page lying on its side is the single easiest way to get an unreadable result out of an otherwise clean scan.

Rotation is the cheapest operation in the format. Each page carries a /Rotate value, and changing it costs nothing in quality — no image is re-encoded and no text is redrawn, so a page can be turned any number of times and stay pixel-perfect.

Which makes uploading a document just to change one number in it particularly hard to justify. The rebuilt file is produced by your own browser; the original never leaves your disk.

Frequently asked questions

Is the rotation permanent?

Yes. PDFLight rewrites the document, so the new orientation is stored in the file and survives being sent to someone else.

Can I rotate only some pages?

Yes. Select exactly the pages you want in the sidebar or the grid view, then rotate only those.

Can I rotate every page at once?

Yes. Press Ctrl+A to select all pages, then click Rotate.

Can I undo a rotation?

Yes, with Ctrl+Z. Every edit in PDFLight is undoable.

Is my file uploaded?

No. The rewritten PDF is built in your browser and saved from there.
