打开 PDFnoted 网站（pdfnoted.com），点击「合并 PDF」入口；直接拖拽或点击选择文件，支持同时上传正文（如Chapter1.pdf）、子章节（Chapter2.pdf）及附录（Appendix_A.pdf、Appendix_B.pdf）等任意数量PDF。
上传后，PDFnoted 自动列出所有文件缩略图。按实际报告结构，用鼠标拖拽调整顺序（如：封面 → 目录 → 第一章 → 第二章 → 附录A → 附录B）；点击任意缩略图可实时预览该页内容，确认章节衔接无误。
确认顺序无误后，点击「合并PDF」按钮；PDFnoted 在后台自动执行无损合并（保留原始字体、超链接、书签层级），约5–10秒生成最终文件；点击「下载」即可获取命名规范的整合PDF（默认名：merged_report_by_chapter.pdf）。
Go to pdfnoted.com, click 'Merge PDF'. Drag and drop all files — e.g., Chapter1.pdf, Chapter2.pdf, Appendix_A.pdf — or click to browse. PDFnoted accepts unlimited PDFs in one batch, with no size limit per file.
Files appear as thumbnails in upload order. Drag them into your desired sequence — e.g., Cover → TOC → Chapter 1 → Chapter 2 → Appendix A → Appendix B. Click any thumbnail to preview its first page instantly — verify logical flow before merging.
Click 'Merge PDF' once ordering is confirmed. PDFnoted performs lossless merging — preserving embedded fonts, hyperlinks, and hierarchical bookmarks. Your unified report generates in ~5–10 seconds; download it instantly as 'merged_report_by_chapter.pdf' (auto-named for clarity).
不会。PDFnoted 保留源文件中已有的书签结构；若原文档含自动生成的目录（如Word导出PDF），建议先在源文件中更新页码再合并，以确保跳转准确。
可以，但需提前输入密码解锁。PDFnoted 会在上传时检测加密状态，弹出密码框；输入正确密码后即可正常参与合并流程。
默认不自动重编页码，但PDFnoted保留各文件原始页码。如需统一连续页码（如‘第1页’起始），建议用PDFnoted的「重排页码」功能（高级选项）在合并后一键设置。
No — PDFnoted preserves existing bookmarks from source files. For auto-generated TOCs (e.g., from Word), update page numbers in the original before merging to ensure accurate hyperlink navigation.
Yes — but you must unlock them first. PDFnoted detects encryption upon upload and prompts for the password. Once entered correctly, protected files join the merge seamlessly.
Page numbers remain unchanged by default. To achieve continuous numbering (e.g., starting from 'Page 1'), use PDFnoted’s built-in 'Renumber Pages' tool — available post-merge under Advanced Options.
