Rotate all or only some PDF pages
- Select one PDF in the PDF page rotation tool.
- Enter the page number to rotate, such as 1,3-5. An empty input is a full page.
- Select either Right 90°, Left 90°, or 180°.
- Click Save Rotate PDF and download the new PDF.
- Check which pages are selected and which are not selected in the PDF viewer.
Page numbers are counted from the first page of the file, including the cover. The chapter numbers may differ from those printed on the paper. Duplicate numbers are applied only once; non-existent numbers or reversed ranges such as 5-3 cannot be used.
means additional rotation in current direction
Right 90° adds 90 degrees to the current rotation value. If the page already has a rotation value of 90 degrees, the result will be 180 degrees. 90° left is the same direction as 270° right. Values exceeding 360 degrees are normalized to all directions except one rotation.
For example, if you select 1,3 in a 3-page document and save it 90° to the right, only the first and third will change, but the second will remain. To extract pages or change their order, use the PDF Split and Page Extract tool. The Rotate tool does not rearrange pages in the order of the numbers entered.
Difference between page rotation and image recompression/skew correction
This function changes the display orientation with the page rotation setting in pdf-lib. It doesn't re-render the page as a photo or recompress it as a JPEG. Although it is different from the method of converting the original text to an image, it is recommended to manually verify the necessary operations such as search, display, and link after saving. If the original is a scan, searchable characters will not be created automatically.
Deskew correction, which straightens problems where scans are skewed by 2 or 3 degrees, is not supported. Editing, cropping, and OCR of the photo itself are also separate tasks. Unlike the PDF viewer's temporary screen rotation, this tool saves the changed rotation values to a new PDF file.
Password, form, electronic signature PDF and confirmation after saving
Input is less than 20MiB·150 pages and output is less than 150MiB. Encrypted documents and documents with AcroForm input form and electronic signature fields are rejected. Password input or electronic signature preservation functions are not provided. Preservation of special document configurations, accessibility tags, etc. is not guaranteed, so archiving of the original is required.
Files are processed within the browser. Interruptions during processing are applied at possible task boundaries, and reading/saving of large documents may not stop immediately. Open the resulting file to check the total number of pages, rotation direction, and whether text and images look as expected.

Frequently Asked Questions
What happens if you rotate left 90 degrees twice?
Saves twice to the same page and rotates a total of 180 degrees when applied. To start over from the original, select the original file.
Does rotating the PDF reduce its size?
The size may vary during the process of re-saving files, but this is not a compression tool and does not guarantee any reduction in size.
