How to use this tool
Select one PDF, choose any settings, then press Process PDF. Review the output carefully before relying on it for important work. No document is sent to OpenToolKit servers. The PDF processing library is loaded from an external CDN.
Example use
Add numbered page labels with adjustable position and size. For example, take a three-page PDF and check all three output pages or the associated downloaded text or PDF.
Limitations
Page labels are newly drawn; existing page numbers in your document are not removed. Encrypted or damaged PDFs may not work, and complicated formatting may not be preserved perfectly. Large pages can consume significant browser memory.
