1. 第 1 步：上传 PDF 文件

访问 PDFnoted 官网（pdfnoted.com），点击「Choose File」或直接拖拽 PDF 文件至上传区。支持密码保护 PDF（需输入密码），单次最大 50MB，无需注册。

2. 第 2 步：选择输出格式并优化提取

在设置面板中，勾选「Extract as Markdown」获取带 # 标题、- 列表、代码块等语义标记的结构化文本；或选择「Plain Text (.txt)」获取纯净无格式内容。PDFnoted 自动识别版面逻辑，跳过页眉页脚与页码，提升准确率。

3. 第 3 步：下载或复制编辑结果

点击「Download」保存为 .md 或 .txt 文件；或直接点击「Copy to Clipboard」一键复制全文。所有文本均可粘贴至 Word、Notion、Obsidian 等任意编辑器，即刻开始修订、摘要或归档。

1. Step 1: Upload Your PDF File

Go to pdfnoted.com, click ‘Choose File’ or drag & drop your PDF into the upload area. Password-protected PDFs are supported (enter password when prompted). Max file size: 50MB. No sign-up required.

2. Step 2: Select Output Format & Refine Extraction

In the settings panel, select ‘Extract as Markdown’ for semantic output (e.g., # headings, - lists, code blocks), or ‘Plain Text (.txt)’ for clean, unformatted content. PDFnoted intelligently skips headers, footers, and page numbers — boosting accuracy.

3. Step 3: Download or Copy Your Editable Output

Click ‘Download’ to save as .md or .txt, or ‘Copy to Clipboard’ to paste instantly into Word, Notion, Obsidian, or any editor — ready for editing, summarizing, or archiving.

小贴士：✅ 小贴士：批量处理前，先用 1–2 页 PDF 测试格式还原效果；含公式/脚注的学术 PDF 建议选 Plain Text 模式避免 Markdown 解析干扰；导出后可在 Obsidian 中用插件自动同步为笔记。

Tips: ✅ Pro tip: Test format fidelity on 1–2 pages before batch processing; for academic PDFs with equations or footnotes, prefer Plain Text mode to avoid Markdown parsing issues; post-export, sync to Obsidian with plugins like ‘QuickAdd’ for instant note creation.

常见问题

FAQ

PDFnoted 支持扫描版 PDF 吗？

不支持。PDFnoted 仅处理含原生文本的 PDF（如 Word 导出、网页打印生成）。扫描件需先用 OCR 工具（如 Adobe Scan、Smallpdf OCR）转为可选中文本，再上传 PDFnoted 提取。

转换后的 Markdown 会保留图片和表格吗？

PDFnoted 当前不提取图片（仅跳过）；表格会被转换为近似 Markdown 表格语法（|---|），但复杂合并单元格可能需手动微调。建议对含重要表格的 PDF 先用专用工具预处理。

我的 PDF 包含中文，转换后乱码怎么办？

PDFnoted 原生支持 UTF-8 中文编码。乱码通常因 PDF 内嵌字体缺失或编码异常导致。请确认该 PDF 在 Adobe Reader 中可正常复制中文；若仍失败，尝试用 Acrobat ‘另存为’优化 PDF 后重试。

Does PDFnoted support scanned PDFs?

No. PDFnoted only works with native-text PDFs (e.g., exported from Word or browsers). For scanned PDFs, first run OCR using tools like Adobe Scan or Smallpdf OCR, then upload the resulting searchable PDF to PDFnoted.

Does the Markdown output retain images and tables?

Images are skipped (not extracted). Tables are converted to basic Markdown syntax (e.g., |---|), but merged cells may require manual cleanup. For PDFs with critical tables, consider pre-processing with dedicated table-extraction tools.

My PDF contains Chinese — why does the output show garbled text?

PDFnoted natively supports UTF-8 Chinese. Garbled text usually stems from missing embedded fonts or broken encoding in the source PDF. Verify Chinese text is copyable in Adobe Reader; if not, try re-saving the PDF via Adobe Acrobat’s ‘Save As Optimized PDF’ before using PDFnoted.
