About Rotate PDF

Viewers can rotate a page on screen, but that setting is not saved in the file, so the next person sees the page sideways again. This tool writes the rotation into the page itself.

Rotation changes only the page’s display attribute — the content stream is untouched, so text stays selectable and the file size does not grow.

How it works

  1. Drop PDF file onto the box above, click it to browse, or paste from the clipboard.
  2. Adjust the options if you need to — the defaults suit most cases.
  3. Press Convert. The work happens on your device, so speed depends on your computer or phone.
  4. Download the result.

About the format

PDF · Portable Document Format · .pdf

The fixed-layout document standard: looks the same on every device and printer, which is why forms, invoices, contracts and reports are shared as PDF.

  • A PDF can contain vector text, embedded fonts, images, form fields, annotations and digital signatures.
  • Scanned PDFs are just pictures of pages; they need OCR before the text can be searched or copied.
  • PDF is an open ISO standard (ISO 32000) since 2008.
