• add_annotationAdd Annotation

  Add one annotation to a page: sticky note (text), highlight, or rectangle (square). Coordinates are in PDF space (origin bottom-left, pt). For signed PDFs, preserveSignatures: true appends an incremental update without invalidating existing signatures (in tagged documents the enclosure in an Annot structure element rides the same update, preserving PDF/UA conformance).

• add_bookmarksAdd Bookmarks (Outline)

  Set the bookmarks (outline) of a PDF. Existing bookmarks are replaced. Nest with children. For signed PDFs, preserveSignatures: true sets them while keeping the signatures intact.

• add_watermarkAdd Watermark

  Overlay a diagonal watermark across the middle of each page ("社外秘" / "DRAFT" / "COPY", etc.). Drawn faintly behind the content by default. In tagged PDFs it is wrapped as an Artifact, preserving PDF/UA conformance. CJK watermarks need fontPath or the PDF_WRITER_FONT environment variable.

• attach_fileAttach File (Embedded File)

  Embed (attach) a file into a PDF. Registers it under /Names /EmbeddedFiles and the catalog /AF, with an AFRelationship. For PDF/A-3 (ISO 19005-3) and Japanese e-bookkeeping-law (電子帳簿保存法) workflows that bundle "a human-readable invoice PDF + machine-readable data (CSV/XML)" into one file.

• create_markdown_pdfCreate PDF from Markdown

  Create a PDF from Markdown. Supports headings, paragraphs, bullet/numbered lists, code blocks, quotes, horizontal rules and tables. Inline decoration markers are stripped and the text rendered plain (single font).

• create_table_pdfCreate Table PDF

  Create a ruled table PDF from headers and row data. Column widths are computed from the content, cells wrap, and the header row is redrawn after page breaks.

• create_text_pdfCreate PDF from Plain Text

  Create a PDF from plain text. Honours line breaks (\n) and treats blank lines as paragraph breaks. Long lines wrap automatically.

• delete_pagesDelete Pagescan change or delete data

  Create a new PDF with the given pages removed. Deleting every page is an error. Pages are copied into a new document, so document-level information (tagged structure, XMP, attachments, AcroForm, bookmarks, etc.) is not carried over. Anything lost is reported in warnings; follow up on the output with attach_file / ensure_tagged / add_bookmarks / set_metadata as needed.

• ensure_pdfaEnsure PDF/A (archival conformance scaffold)

  Put an existing PDF onto the PDF/A "vessel" (the PDF/A counterpart of ensure_tagged). Choose the flavour: "pdfa-3b" (default) / "pdfa-4" / "pdfa-4f". Supplies only the missing document-level requirements: the trailer /ID (ISO 32000-1 14.4), an sRGB OutputIntent (GTS_PDFA1; an ICC profile is generated and embedded), and XMP pdfaid. **The -4 flavours additionally set the header to PDF 2.0 and delete the Info dictionary** (-4 forbids Info unless the catalog has /PieceInfo — stricter than ISO 32000-2 14.3.3). **Content, structure tree and fonts are never touched.** **Documents with attachments mus…

• ensure_taggedEnsure Tagged (PDF/UA scaffold & repair)

  Put an existing PDF onto the PDF/UA-1 "vessel". If it is already tagged, the structure tree is untouched and only missing document-level requirements are supplied (MarkInfo / Lang / DisplayDocTitle / XMP pdfuaid:part and dc:title). For untagged documents, a minimal structure tree (each page = one P element) is created so the content becomes reachable by assistive technology. **IMPORTANT**: machines cannot infer meaning — headings, tables, lists, reading order and figure alt text are NOT created. The new tree is a scaffold, not an accessible document; it needs human review. If you can build the…

• extract_pagesExtract Pages

  Create a new PDF containing only the given pages. The given order is preserved, so extraction doubles as reordering. Pages are copied into a new document, so document-level information (tagged structure, XMP, attachments, AcroForm, bookmarks, etc.) is not carried over. Anything lost is reported in warnings; follow up on the output with attach_file / ensure_tagged / add_bookmarks / set_metadata as needed.

• fill_formFill Form (AcroForm)

  Fill field values into an existing PDF's interactive form (AcroForm). If you do not know the field names, pass a nonexistent one — the error lists every field name and type. CJK values need fontPath or the PDF_WRITER_FONT environment variable. flatten: true makes the form non-interactive after filling, but on a tagged PDF that breaks PDF/UA conformance and additionally requires allowBreakingTags: true. XFA forms are not supported.

• flatten_formFlatten Formcan change or delete data

  Flatten an existing PDF's interactive form (AcroForm), keeping the filled appearance while removing interactivity. Use it to freeze values before distribution. If existing values contain CJK text, set fontPath or PDF_WRITER_FONT in case appearances must be regenerated. On tagged PDFs, Widget annotations disappear and Form structure elements are left dangling, so it refuses by default (allowBreakingTags: true to force).

• merge_pdfsMerge PDFs

  Merge multiple PDFs into one, in the given order. Document metadata is carried over from the first file. Pages are copied into a new document, so document-level information (tagged structure, XMP, attachments, AcroForm, bookmarks, etc.) is not carried over. Anything lost is reported in warnings; follow up on the output with attach_file / ensure_tagged / add_bookmarks / set_metadata as needed.

• reorder_pagesReorder Pages

  Reorder pages. order must list every page exactly once, in the new order. Pages are copied into a new document, so document-level information (tagged structure, XMP, attachments, AcroForm, bookmarks, etc.) is not carried over. Anything lost is reported in warnings; follow up on the output with attach_file / ensure_tagged / add_bookmarks / set_metadata as needed.
