Convert documents between formats using Pandoc CLI (Markdown, DOCX, PDF, HTML, EPUB, PPTX, ODT, RTF, LaTeX, CSV/TSV, Jupyter, etc.). Use when: (1) converting file formats, (2) generating DOCX/PDF from Markdown, (3) creating slide decks (PPTX/Beamer/Reveal.js), (4) extracting text from DOCX/EPUB/ODT, (5) producing EPUBs, (6) any Pandoc conversion task.

pandoc input.md -o output.pdf
# Chinese support (XeLaTeX)
pandoc --pdf-engine=xelatex -V CJKmainfont="Noto Sans CJK SC" input.md -o output.pdf
# LuaLaTeX (alternative CJK)
pandoc --pdf-engine=lualatex -V CJKmainfont="Noto Sans CJK SC" input.md -o output.pdf
# HTML intermediate (wkhtmltopdf)
pandoc --pdf-engine=wkhtmltopdf -s input.md -o output.pdf
# WeasyPrint (HTML intermediate)
pandoc --pdf-engine=weasyprint -s input.md -o output.pdf
# Typst (fast, no LaTeX needed)
pandoc --pdf-engine=typst input.md -o output.pdf
# ConTeXt
pandoc -t context input.md -o output.pdf
# roff ms (via pdfroff)
pandoc -t ms input.md -o output.pdf
# latexmk (auto-run LaTeX as needed)
pandoc --pdf-engine=latexmk input.md -o output.pdf
# Pass extra options to PDF engine
pandoc --pdf-engine=xelatex --pdf-engine-opt=-shell-escape input.md -o output.pdf
# Debug: output intermediate LaTeX
pandoc -s -o output.tex input.md
# Then test: pdflatex output.tex
Supported PDF engines: pdflatex, xelatex, lualatex, latexmk, tectonic, wkhtmltopdf, weasyprint, pagedjs-cli, prince, context, groff, pdfroff, typst.
Default engines by intermediate format:
-t latex(or none): pdflatex-t context: context-t html: weasyprint-t ms: pdfroff-t typst: typst
Chinese PDF requirements: XeLaTeX or LuaLaTeX + CJK font. If CJKmainfont is set, xeCJK is needed (xelatex) or luatexja (lualatex). fontspec is required for xelatex/lualatex.
LaTeX packages needed: amsfonts, amsmath, lm, unicode-math, iftex, fancyvrb, longtable, booktabs, multirow, graphicx, bookmark, xcolor, soul, geometry (with geometry variable), setspace (with linestretch), babel (with lang).
默认中英混排 PDF 字体方案（实测可用）
Linux 系统字体路径：/usr/share/fonts/
| 用途 | 字体包 | 字体名（pandoc -V 参数） |
|---|---|---|
| 中文正文/标题 | 文泉驿正黑 | wqy-zenhei |
| 英文正文/标题 | Helvetica Neue | helvetiker |
| 代码块 | Courier New / Latin Modern Mono | 默认 monospace 即可 |
标准生成命令（中英混排）：
pandoc input.md \
-o output.pdf \
--pdf-engine=xelatex \
-V CJKmainfont="wqy-zenhei" \
-V mainfont="helvetiker" \
-V monofont="Courier New" \
-V geometry:margin=1in \
-V linestretch=1.1 \
-V fontsize=12pt
注意事项：
mainfont（英文）和CJKmainfont（中文）必须同时设置，否则中英文混排时其中一种会回退到默认 CM 字体- 不要混用 pdflatex（不支持中文）和 xelatex
- 代码块默认用 Latin Modern Mono，若要 Courier 风格可加
-V monofont="Courier New" - 字体名大小写敏感，敲错 Pandoc 只给警告但仍出 PDF（回退到默认字体），需注意检查输出
字体名参考（xelatex + fontspec）：
# 查看已安装的中文字体（Linux）
fc-list :lang=zh -f '%{family}\n' | sort -u
# 查看已安装的英文无衬线字体
fc-list | grep -i 'helvetica\|arial\|sans' | head -20
# 测试字体是否可用（直接 pandoc -V CJKmainfont="字体名"）
DOCX Customization
Generate a reference doc to customize styles:
pandoc -o custom-reference.docx --print-default-data-file reference.docx

# Convert web page
pandoc -f html -t markdown https://example.com -o page.md
# Batch convert (shell)
for f in *.md; do pandoc "$f" -o "${f%.md}.docx" -s; done
# Extract text from Word (for processing)
pandoc document.docx -t plain -o text.txt
# Markdown to styled HTML with TOC

# Convert between bibliography formats
pandoc chem.bib -s -f biblatex -t csljson -o chem.json
pandoc chem.json -s -f csljson -t biblatex -o chem.bib
# Shift heading levels (e.g., HTML docs with H1 title → make H2 the top section)
pandoc --shift-heading-level-by=-1 input.md -o output.md
Troubleshooting
- PDF fails: Ensure LaTeX is installed (
which pdflatex). Try--pdf-engine=xelatexfor CJK. - Chinese garbled: Use
--pdf-engine=xelatex -V CJKmainfont="FontName". - Images not found: Use
--resource-path=.:imagesto set search paths. - Missing styles in DOCX: Use
--reference-doc=reference.docx. - Code blocks not highlighted: Use
--syntax-highlighting=pygments(not--highlight-style). - List all extensions:
pandoc --list-extensions=markdown - Debug PDF: Output intermediate:
-o output.texinstead of.pdf. - Exit codes: See
references/advanced.mdfor full exit code table. - Untrusted input: Use
--sandboxto limit IO operations.
