How to Prevent Annotations from Rotating When Replacing PDF Pages
Question details
The user needs to stop lines and annotations from unexpectedly rotating by 90 degrees when replacing pages in a PDF document.

- Adobe Acrobat DC
- Device & OS
- not provided
- Scenario
- Replacing pages within an existing PDF document that already contains specific annotations or drawing markups.
- Observed behavior
- Existing lines and annotations on the original PDF rotate by 90 degrees after the page replacement is executed.
Before replacing pages, verify the dimensions and orientation of both the original PDF pages and the replacement pages to ensure they match perfectly.
Match Page Orientation and Dimensions Before Replacing
Ensuring that the original and replacement pages have identical size and rotation settings prevents annotations from shifting or rotating.
Page replacement can cause annotations to retain their original coordinates. If the replacement page has a different inherent rotation or dimension, the coordinates map differently, causing the 90-degree rotation effect.
Open the original PDF, navigate to the specific page, and check its document properties or crop box settings to note the exact page size and rotation.
Open the replacement PDF file and verify its page size and rotation settings to see if they match the original file exactly.
If the replacement page has a different orientation, rotate the page manually to match the original page and save the file before executing the replace command.
Proceed with the Replace Pages tool. The annotations should now retain their correct orientation.

Flatten Annotations on the Original Document
Flattening merges annotations into the base page content, preventing them from rotating independently during modifications.
Replace PDF Pages and Manage Annotations with WPS PDF
WPS Office provides a reliable and user-friendly PDF editor to replace pages without messing up your annotations. Easily match page orientations and keep your markups intact.
- 1. Open PDF in WPS Office: Launch WPS Office and open your PDF document containing the annotations.
- 2. Navigate to the Page tab: Click on the 'Page' tab in the top menu bar to access the PDF page management tools.
- 3. Select Replace Page: Click the 'Replace' button, choose the replacement PDF file from your computer, and specify the page range you wish to swap.
- 4. Confirm the replacement: Click 'OK' to replace the page. WPS PDF will handle the background formatting to keep your annotations in their correct orientation.

Frequently Asked Questions
Why do my PDF annotations rotate when I insert or replace a page?
Annotations have fixed coordinates based on the page's original dimensions and rotation data. If the new page has different underlying orientation settings, the PDF reader applies the original coordinates to the new dimensions, making the annotations appear rotated by 90 degrees.
Can I fix annotations that have already rotated?
Yes, you can manually select the rotated annotations, drawing markups, or lines, and rotate them back 90 degrees using the object editing or properties tool in your PDF editor.
Is there a difference between drawing markups and page content?
Yes. Drawing markups and annotations are dynamic elements layered on top of the PDF and can be edited, deleted, or rotated independently. Page content forms the flattened base layer of the PDF and cannot be moved without using advanced content editing tools.
