1. 上传PDF文件

访问PDFnoted官网（pdfnoted.com），点击「Choose File」上传需处理的PDF。支持批量上传（单次最多5个），自动识别文字型PDF；若为扫描件，PDFnoted会调用OCR引擎识别中文与英文混合内容。

2. 选择输出格式为Markdown

在转换设置中，将「Output Format」切换为「Markdown (.md)」。PDFnoted默认启用‘智能结构识别’——自动还原H1–H3标题层级、有序/无序列表、引用块及行内代码，避免纯TXT导致的格式丢失。

3. 下载并导入笔记工具

点击「Convert」后约3–10秒生成Markdown文件。下载后可直接拖入Obsidian、Typora或Notion（通过「Import → Markdown」）。PDFnoted生成的.md文件兼容Front Matter（含PDF源名与时间戳），方便归档与双向链接。

1. Upload Your PDF File

Go to pdfnoted.com, click ‘Choose File’ to upload your PDF. Supports up to 5 files at once. For text-based PDFs, extraction starts instantly; for scanned PDFs, PDFnoted applies OCR to accurately detect both Chinese and English characters.

2. Select Markdown as Output Format

In the conversion settings, select ‘Markdown (.md)’ as output format. PDFnoted enables ‘Smart Structure Detection’ by default—restoring H1–H3 headings, ordered/unordered lists, blockquotes, and inline code, so you never lose semantic formatting like plain TXT does.

3. Download & Import into Your Note-Taking App

Click ‘Convert’—your Markdown file generates in 3–10 seconds. Download it and drag directly into Obsidian, Typora, or Notion (via ‘Import → Markdown’). Every PDFnoted .md file includes YAML Front Matter (source filename + timestamp), enabling smart archiving and bidirectional linking.

小贴士：小贴士：转换前删除PDF页眉页脚可提升Markdown结构准确性；长文档建议分章节上传；导出后用VS Code + 'Markdown All in One'插件一键美化排版。

常见问题

FAQ

扫描版PDF能转出准确的Markdown吗？

可以。PDFnoted集成多语言OCR引擎，对中英文混合扫描件识别准确率超92%（实测A4文档，12pt字体）。建议使用清晰度≥150dpi的PDF以获得最佳效果。

表格和图片会被保留吗？

表格会转为标准Markdown表格语法（|---|），图片则生成占位链接（如![](fig1.png)），并附原始图片文件包（ZIP下载）。公式暂不支持LaTeX渲染，但保留原文本位置。

是否支持批量处理与API调用？

免费版支持单次最多5个PDF批量转换；专业版（$8/month）提供API密钥、每日100页限额、自定义Front Matter模板及企业级Webhook通知。

Does PDFnoted handle scanned PDFs accurately?

Yes. PDFnoted uses a multilingual OCR engine—achieving >92% accuracy on Chinese-English scanned PDFs (tested on A4 docs, 12pt font). For best results, use PDFs with resolution ≥150 DPI.

Are tables and images preserved in Markdown output?

Tables convert to standard Markdown syntax (|---|); images become placeholder links (e.g., ![](fig1.png)) + bundled image files (ZIP download). Math formulas retain their textual position but aren’t rendered as LaTeX yet.

Does PDFnoted support batch processing or API access?

Free plan supports up to 5 PDFs per batch. Pro plan ($8/month) unlocks API access, 100 pages/day quota, custom YAML Front Matter templates, and enterprise webhook notifications.
