Rotate PDF

A scanned page that came out sideways, a whole document that landed upside-down, or just a handful of pages shot in landscape when the rest are portrait — Rotate PDF fixes all of it, page by page or all at once, entirely inside your browser.

What is Rotate PDF?

Rotate PDF is a tool that turns pages inside a PDF 90° left, 90° right, or a full 180°, and saves the result as a new document, leaving your original file untouched. Rotate every page at once, just the odd or even pages, a specific selection, or one page at a time using the per-page controls.

You choose your file, fix the orientation of whichever pages need it, and the tool processes everything directly in your browser using pdf-lib — no byte of your document is ever uploaded to a server.

Each page shows its current rotation angle live, so you can see exactly what will be applied before you download.

When should you use it?

This tool is most useful whenever a PDF's pages aren't sitting the right way up.

• Fixing a scanned document where some pages came out sideways or upside-down.
• Correcting a batch of photos or landscape pages exported into a mostly-portrait report.
• Straightening a signed page that was scanned in the wrong orientation.
• Turning an entire PDF 180° when it was scanned upside-down from front to back.
• Preparing a document for printing or sharing where every page needs to read the same way.

The benefits

Manually fixing page orientation usually means printing to PDF or juggling desktop software. A dedicated online tool keeps things far simpler:

• Rotate the whole document, just odd/even pages, or a specific selection in one click.
• Fine-tune individual pages afterward with dedicated Left/Right/180° buttons.
• See each page's current rotation angle at a glance before downloading.
• Nothing leaves your device, so sensitive or confidential PDFs stay private throughout.
• Completely free, with no watermark added to your output file.

How the rotation works

Rotate PDF reads your source file's existing page rotations and lets you adjust them — 90°, 180°, or 270° at a time — using pdf-lib. When you download, the new rotation angle is written directly into each page's metadata, so there is no re-rendering or quality loss; the page content itself is untouched, only its orientation changes.

Common mistakes to avoid

A little care goes a long way when fixing orientation on a larger document:

• Rotating a page twice by mistake — check the angle shown under each thumbnail before downloading.
• Trying to process a password-protected or encrypted PDF, which the tool cannot read without the file being unlocked first.
• Using "All Left/Right/180°" when only a handful of pages actually need fixing — a selection is faster and safer.
• Overwriting your original file before confirming the rotated PDF opens and reads correctly.

Tips for best results

A few small habits make the whole process smoother:

• Use Odd/Even Pages when a scanner alternated orientation between sides.
• Select several pages at once and use the "Selected" rotate buttons instead of one page at a time.
• Zoom in on thumbnails before rotating if it's hard to tell which way a page should face.
• Keep your original file until you've confirmed the rotated PDF opens and reads correctly.
