Rotate PDF Pages

To rotate pages of a document, use Document Engine’s /api/build endpoint(opens in a new tab).

For more information, refer to the API reference to learn about the /api/build endpoint and all the actions you can perform on PDFs with Document Engine.

For an overview of multipart requests, refer to the brief tour of multipart requests blog post.

Rotating Pages of a File on Disk

Send a multipart request to the /api/build endpoint(opens in a new tab), attaching input files and the instructions JSON:

The example below rotates the first two pages of an eight-page document 90 degrees clockwise. After rotating the first two pages, the result is merged with the remaining six pages of the document to get the final output PDF.

Terminal window
curl -X POST http://localhost:5000/api/build \
-H "Authorization: Token token=<API token>" \
-F document=@/path/to/document.pdf \
-F instructions='{
"parts": [
{
"file": "document",
"pages": {
"start": 0,
"end": 1
},
"actions": [
{
"type": "rotate",
"rotateBy": 90
}
]
},
{
"file": "document",
"pages": {
"start": 2,
"end": 7
}
}
]
}' \
-o result.pdf

Rotating Pages of a File from a URL

Send a multipart request to the /api/build endpoint(opens in a new tab), attaching a URL pointing to an input file and the instructions JSON.

The following example rotates all the pages of the document at the URL 90 degrees clockwise:

Terminal window
curl -X POST http://localhost:5000/api/build \
-H "Authorization: Token token=<API token>" \
-F instructions='{
"parts": [
{
"file": {
"url": "https://pspdfkit.com/downloads/examples/paper.pdf"
},
"actions": [
{
"type": "rotate",
"rotateBy": 90
}
]
}
]
}' \
-o result.pdf
