📑

📚

Bulk Rotation

Apply rotation to all pages at once if you scanned the whole batch in the wrong direction.

🔐

Dune Safe™

The file is never uploaded to the Internet. Rotation happens in your device memory.

Selectable Text

When rotating, we also update text coordinates so you can continue copying and pasting.

🚀

Permanent Save

It's not just a preview. The downloaded file will open correctly on any computer or mobile.

Metadata Rotation without Re-encoding

Why our tool is faster and safer.

/Rotate Attribute Modification

Instead of 'repainting' every pixel of your document (which would lose quality), DuneTools modifies an internal PDF tag called /Rotate. This tells the reader how to display the page. The result is 100% original quality and instant processing.
💡

Your images and signatures don't lose a single bit of definition.

Local Privacy (WASM)

Your architectural plans or legal papers don't need to travel to a server abroad just to be rotated. We use WebAssembly to do it in your own browser securely and privately.
💡

Total security for confidential blueprints and contracts.

Orientation Standardization

Mixing horizontal and vertical PDFs often causes printing issues. Our tool allows you to standardize the entire document to Portrait or Landscape before printing, avoiding cut-off pages.
💡

Avoid printing errors due to mixed orientations.

When is it Necessary to Rotate a PDF?

Scan Correction

Sometimes we put the paper upside down in the scanner. No need to rescan: upload the file, rotate the wrong pages 180 degrees and you're done.

📊

Tables and Excel in Landscape

Have a report where some sheets are wide tables that come out rotated? Rotate them to Landscape position to read them comfortably on screen.

📱

Reading on Tablets/Mobile

Adjust the orientation of ebooks or notes to fit better with your mobile device screen.

PDF Rotation FAQs

Clarifying doubts about saving and quality.

Is the change permanent?
Yes. When you click 'Save/Download', we generate a new PDF file with the corrected orientation. Next time you open it (in Adobe, Chrome, etc.), it will look straight.
Can I straighten a crooked document (e.g. 5 degrees)?
No. This tool performs structural rotations of 90 degrees. If your scan is slightly tilted (skewed), you need a 'Deskew' or perspective correction tool.
Can I rotate only odd pages?
Currently you must manually select the pages you want to turn. We are working on smart selectors (Odd/Even) for future versions.
Does it affect text recognition (OCR)?
It improves OCR. Text reading programs work much better when the page is in the correct orientation (vertical) rather than lying down.
Can I mix vertical and horizontal pages?
Yes, the PDF standard allows mixed orientations in the same file. Just be sure to warn the print shop if you are going to print it.
Is there a page limit to rotate?
In the free version you can upload documents with hundreds of pages. Being processed locally, it depends on your computer memory, but 500+ pages are usually no problem.
Is it reversible?
If you save the file, the change is permanent. But you can always upload it again and rotate it in the opposite direction (-90°) to put it back as it was.
What happens to comments and notes?
Comments, sticky notes, and signatures rotate solidarily with the page, maintaining their correct relative position regarding the text.
