About this markdown to print-ready pdf
Edit Markdown locally. Three themes provide native vector text, headers, footers, page numbers and a contents list with page destinations. Short code blocks stay together; long blocks split by lines where possible. Uses the bundled MIT markdown-it parser with raw HTML disabled; no extra installation or service fee Parses and structures office document payloads locally in memory without transmitting private company files to external servers.
Document parsing & data extraction pipeline
Performs non-destructive manipulation of Portable Document Format (PDF) binary object streams in accordance with ISO 32000-1 and ISO 32000-2 (PDF 2.0). Operates on underlying PDF cross-reference tables (XRef), catalog dictionaries, page trees (/Pages), and content streams via pdf-lib and PDF.js. Implements symmetrical margin cropping based on existing CropBox / MediaBox origin coordinates [x, y], executes 90-degree page rotations, merges/splits page trees, and preserves AcroForm interactive form fields, annotations, and bookmarks.

File size & structure constraints
UTF-8 input must be smaller than 5,000,000 bytes. Limits: 20,000 nodes, depth 40, 1,000 headings, 2,000 rules per style block, 200 pages, 100,000 layout steps and 30 seconds including reading. Synchronous parsing/layout cannot be interrupted mid-operation. Editing or changing layout clears the old result. This is a limited print layout, not a full CSS renderer or complete W3C certification. Scripts, forms, SVG/MathML, remote images/fonts, positioning and imported styles are removed. A table row taller than a page or multi-page rowspan is rejected. Left/right breaks mean the next sheet, without duplex parity. Long contents titles and headers may be ellipsized; body text is preserved. Raster images/emoji may remain bitmaps. Chromium is verified; other browsers, native save dialogs and physical printers remain unverified.
Markdown to Print-Ready PDF parses structured OpenXML and PDF data locally. Review exported tables or sheets against original files.
Zero-upload document security boundary
File buffers and document assets in Markdown to Print-Ready PDF are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
Document schemas & interchange standards
ECMA-376 Office Open XML specifications and ISO 32000 PDF reference standards:
- Finite CSS paged-media geometry and Chromium native printing; not complete W3C conformance or all-browser verification
