Markdown 转换：全部可用目标Markdown conversions: every available target
Markdown 是这组路线里最像「源文件」的格式：它只有结构，没有版式。所以每条出路的差别不在能不能转，而在目标格式肯不肯接住这些结构——Word 与 HTML 会保留标题、列表与表格，PDF 与图片只留下渲染后的样子，表格数据则要求文档里真的有一张表。Markdown is the closest thing here to a source file: it carries structure, not layout. The routes therefore differ less in whether they work than in what the target is willing to keep — Word and HTML keep headings, lists and tables, PDF and images keep only the rendered look, and spreadsheet targets require the document to actually contain a table.

HTMLHTML 1 步1 step
MarkdownMarkdown HTMLHTML
浏览器本地把 .md 渲染成可直接双击打开的完整 HTML：GFM 表格与任务列表可用，样式内联，脚本与事件属性在净化阶段移除。Render .md into a complete, double-clickable HTML document locally: GFM tables and task lists work, styles are inlined, scripts and event attributes removed.
-
Word (.docx)Word (.docx) 2 步2 steps
MarkdownMarkdown HTMLHTML Word (.docx)Word (.docx)
在浏览器本地把 .md 转成 .docx：标题层级、列表、表格、代码块写成真实 Word 段落，不是截图。批量、可预览、零网络请求。Convert .md to .docx in your browser: headings, lists, tables and code become real Word paragraphs, not a screenshot. Batch, previewable, zero requests.

PDFPDF 2 步2 steps
MarkdownMarkdown HTMLHTML PDFPDF
Markdown → HTML → PDF，本地按 A4 逐页切片成图像型 PDF。好处是哪台机器打开都一样，代价是没有文字层、不可选中检索。Markdown → HTML → PDF, sliced page by page onto A4 locally. It looks identical everywhere; the price is no text layer, so nothing is selectable or searchable.
-
Excel (.xlsx)Excel (.xlsx) 4 步4 steps
MarkdownMarkdown HTMLHTML JSONJSON CSVCSV Excel (.xlsx)Excel (.xlsx)
Markdown 表格经 HTML、JSON、CSV 三步落进一张工作表：15 位以内的数字变可求和，`00424`、日期串和 16 位以上的账号保持原字符，`=` 开头加护栏。全程离线。A GFM table lands in a worksheet via JSON and CSV: numbers become summable, 00424 and 16-digit IDs stay text, and a leading = is disarmed. Offline.
-
CSVCSV 3 步3 steps
MarkdownMarkdown HTMLHTML JSONJSON CSVCSV
把文档里的管道表变成能再计算的 CSV：首行当列名，其余行当记录，数字按值写出不被显示格式改写，文件带 BOM 让 Excel 直接双击不乱码。A pipe table becomes a CSV you can compute on: first row as column names, values written as values, and a BOM so Excel opens the file without mojibake.
-
纯文本 (TXT)plain text (TXT) 2 步2 steps
MarkdownMarkdown HTMLHTML 纯文本 (TXT)plain text (TXT)
去掉记号、留下阅读顺序：标题变成一行文字，链接把地址附在文字后，列表按位置重新编号。全程离线，不经过服务器。Strip the markup: headings become lines, links keep their URL after the text, and ordered lists are renumbered. Offline — nothing is uploaded.
-
JSONJSON 2 步2 steps
MarkdownMarkdown HTMLHTML JSONJSON
把 Markdown 表格变成对象数组：表头行给出键名，两张以上按 `##` 小标题分组，没有表格时读代码块。全程离线，不请求图片与脚本。Turn Markdown tables into objects: the GFM header row supplies keys, and several tables group under their `##` headings. Offline, no uploads.
-
PNGPNG 2 步2 steps
MarkdownMarkdown HTMLHTML PNGPNG
Markdown 先按 GFM 渲染成带样式的 HTML，再无损截成一张长图：表格有条纹、行内 SVG 图形保留。高度超过 32768 px 会报错而不是截断。GFM renders to styled HTML, then the page is captured losslessly: striped tables and inline SVG diagrams survive the trip. Past 32768 px it fails, not trims.
-
JPEGJPEG 3 步3 steps
MarkdownMarkdown HTMLHTML PDFPDF JPEGJPEG
Markdown 先按 GFM 渲染成带样式的 HTML，再整篇渲染一次、按 A4 切片存无损页面，逐页编码成 JPEG；多页打包成 ZIP。全程离线。GFM renders to styled HTML first, then the document is captured once, sliced into lossless A4 pages and encoded JPEG by JPEG, zipped when there are several.
-
WebPWebP 3 步3 steps
MarkdownMarkdown HTMLHTML PDFPDF WebPWebP
Markdown 先按 GFM 渲染成带样式的 HTML，再整篇渲染一次、按 A4 切成无损片段，逐页编码成 WebP；多页打包 ZIP。全程离线。GFM renders to styled HTML first, then the document is captured once, sliced into lossless A4 pages and encoded WebP page by page, a ZIP when several.
这个来源格式的共同限制What holds for every target from this source
- 源文件先按 BOM / NUL 识别 UTF-16，再按 UTF-8 → GB18030 → GBK 依次解码；四种都不成立时报解码失败，不产出乱码文件Input is decoded UTF-16 (by BOM or NUL spacing), then UTF-8 → GB18030 → GBK; if none of the four works the route reports a decode failure instead of writing mojibake
- HTML 之外的格式只能看到渲染结果或表格结构：CSS 版式、脚注、mermaid 图与自定义语法会被降级或丢弃Every target except HTML sees either the rendered result or the table structure, so CSS layout, footnotes, mermaid diagrams and custom syntax are flattened or dropped
- 指向 http(s) 的图片在渲染或打包前被剥掉；相对路径的图片只有在同一批次里也选入那个文件时才有字节可用http(s) images are stripped before rendering or packing; a relative image only has bytes when that file is part of the same batch
- 一整批文件共用一个目标格式；混合格式批次只提供对所有文件都成立的目标One target format applies to the whole batch; a mixed-format batch only offers targets that work for every file in it
常见问题Questions people actually ask
Markdown 转 PDF 后还能选中文字吗？Is the text in a Markdown to PDF result selectable?
不能。这条路线先把 Markdown 渲染成 HTML，再整页拍成图像切片写入 PDF，所以 PDF 里是页面图像，不是文字层。要可编辑的文档请选 Word；要能被搜索的文字请选 HTML 或 TXT。No. The route renders Markdown to HTML and slices that rendering into page images, so the PDF holds pictures of pages rather than a text layer. Choose Word for an editable document, or HTML/TXT when the text itself has to stay searchable.
为什么 Markdown 转 Excel 要求文档里有表格？Why does Markdown to Excel need a table in the document?
Excel 的每一格都要求行列坐标，而标题和段落没有坐标。转换器先找 Markdown 表格（或一段能被当作 JSON 数组读的代码块），找不到就报错，而不是交出一张空表。Every Excel cell needs a row and a column, and a heading or paragraph has neither. The converter looks for a Markdown table, or a code block that parses as a JSON array, and fails when there is none rather than handing back an empty sheet.
链接和图片会跟着走吗？Do links and images travel with the result?
链接会：HTML 与 Word 保留可点击的地址，TXT 会把地址附在链接文字后面。图片分两种：data URI 内嵌的会跟着走；指向网络或相邻路径的取不到字节，渲染类目标会按张数披露。Links do: HTML and Word keep clickable addresses, and TXT appends the address after the link text. Images depend on where the bytes are — embedded data URIs travel, while network or sibling-path references have no bytes and rendering targets count them in the drop disclosure.
一次能转多少个文件？How many files can one batch hold?
最多 200 个文件，单个文件上限 100 MB；超过 5 个文件或 20 MB 的批次会先弹确认。每个文件独立执行路线，一个失败不会阻断其余文件。Up to 200 files and 100 MB per file; a batch over five files or 20 MB asks for confirmation first. Each file walks the route on its own, so one failure does not stop the rest.
