How this service works
Documents: DOCX template fill, Office to PDF, any file to Markdown, PDF to Word, OCR, PDF pipeline.
Output
Returns the modified PDF with the new bookmark/outline structure applied, either as an inline base64-encoded file or as a temporary 24-hour download URL. The response includes the output file size, page count, outline depth, total bookmark count, and a report of any active content (XFA forms, JavaScript) removed during processing.
Example use cases
Add chapter bookmarks to a report
“I have a 20-page quarterly report at https://example.com/q4-report.pdf. Please add bookmarks for 'Executive Summary' on page 1, 'Financial Results' on page 5 (with sub-sections 'Revenue' on page 6 and 'Expenses' on page 8), and 'Outlook' on page 15. Return the bookmarked PDF as a download URL.”
Remove all bookmarks from a PDF
“Strip every bookmark from this PDF — send it base64 encoded as the input and give me back the cleaned version as base64. The outline list should be empty.”
Structure a technical manual for navigation
“This technical manual at https://example.com/manual.pdf needs a full navigable outline: 'Getting Started' on page 1, 'Installation' on page 3 with children 'Windows Setup' on page 4 and 'Linux Setup' on page 7, 'Configuration' on page 10, and 'Troubleshooting' on page 18. Set all top-level bookmarks to be expanded by default and return a download link.”

Endpoint

Choose this endpoint when you need to programmatically set, replace, or clear the navigational bookmark/outline structure of an existing PDF without altering its content. It is ideal for publishing workflows where chapter navigation must be added to generated PDFs, for sanitizing PDFs by stripping old bookmarks, or for injecting a structured table of contents into reports and manuals. It also automatically strips dangerous active content (XFA, JavaScript), making it useful as a light security step.
Side effects
- PDF URL exceeds 20 MB or is inaccessible/private — request refused
- Base64 payload exceeds 10 MB decoded — request rejected
- Outline tree exceeds 1,000 total bookmarks or 8 nesting levels — validation error
- Page numbers in the outline reference pages beyond the PDF's actual page count — error
- Invalid or corrupt PDF input — processing failure
- URL points to an internal or IP-literal host — refused for security
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| url | — | Public http(s) URL of the PDF (at most 20 MB; private, internal and IP-literal hosts are refused); or use pdf_base64. |
| output | string | base64 (default): the file comes back inline as base64. url: the file is stored for 24 hours and the reply carries a download link (url, expires_at, bytes, content_type, sha256) instead of the base64, which keeps the file out of your context window. |
| outline | array | The new bookmarks as a tree of {title, page, open?, children?}: at most 1,000 in all and 8 levels deep; an empty list removes every bookmark. They replace the ones the PDF has. |
| pdf_base64 | — | The PDF as base64 (at most 10 MB decoded per request); or use url. |
