PDF Page Rotator

Rotate 1 page(s) by 90°, keeping the other pages unchanged.

How it works

• Read the document's page tree.
• Resolve the requested pages and add the rotation to each page's existing /Rotate value.
• Write the updated document, leaving every other page unchanged.

• Nothing is uploaded; the rewrite runs in your browser.

Methodology

1. Parse the page selection and validate each page against the real page count.
2. Add the requested rotation to each selected page's /Rotate entry, combining with any existing rotation.
3. Leave every unselected page untouched and refuse an encrypted or unsupported input by name.

Usage

1. Choose or drop a PDF.
2. Enter the pages to rotate and choose 90, 180 or 270 degrees.
3. Run the rotation and download the result.

Examples

These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.

Rotate page 1 by 90 degrees

{
  "pageCount": 4,
  "selection": "1",
  "rotation": 90,
  "baseName": "report"
}

Rotate pages 2-3 by 180 degrees

{
  "pageCount": 4,
  "selection": "2-3",
  "rotation": 180,
  "baseName": "report"
}

Limitations

Only the pages you choose

Rotation updates the selected pages' /Rotate value and writes a fresh valid PDF; unselected pages are copied unchanged.

The rotation is combined with any existing page rotation so repeated edits stay predictable.
