访问 PDFnoted 官网，点击「拆分 PDF」工具入口；拖拽或点击选择需处理的 PDF 文件（支持最大 200MB）。文件全程在浏览器中解析，不会上传至任何服务器。
在输入框中输入目标页码，支持多种格式：单页（如“7”）、连续区间（如“10–15”）、多段组合（如“1, 3–5, 22”）。PDFnoted 会实时预览将生成的拆分文件数量与命名规则。
点击「开始拆分」按钮，PDFnoted 在本地快速处理并生成多个独立 PDF 文件；每个文件按页码自动命名（如“document_10-15.pdf”）。一键打包下载 ZIP，或逐个保存。
Go to PDFnoted’s official site, click the ‘Split PDF’ tool. Drag & drop or select your PDF (up to 200 MB). The file is parsed entirely in your browser — never uploaded.
Enter page numbers in the input field: single page (e.g., “7”), range (e.g., “10–15”), or multiple segments (e.g., “1, 3–5, 22”). PDFnoted previews output count and filenames instantly.
Click ‘Split Now’. PDFnoted processes locally and generates separate PDFs named by range (e.g., “document_10-15.pdf”). Download all as ZIP or save individually.
不会。PDFnoted 所有操作均在您的浏览器中完成（WebAssembly 技术），原始文件和拆分结果均不经过服务器，确保敏感文档（如合同、身份证扫描件）100% 本地处理、零泄露。
可以，但需先输入正确密码解锁。PDFnoted 支持带用户密码（打开密码）的 PDF；若文档设定了编辑限制（如禁止打印），请先解除权限或使用其他工具解密后再操作。
完全保留。PDFnoted 严格按您输入的页码顺序提取，例如输入“5, 1–3”将生成两份文件：第一份含第 5 页，第二份含第 1–3 页（顺序不变），原始排版、字体、链接全部 intact。
No. PDFnoted runs entirely in your browser via WebAssembly — no file leaves your device. Your original PDF and split outputs stay local, guaranteeing full privacy for sensitive docs.
Yes — if you know the open password. PDFnoted handles user-password-protected PDFs. However, it cannot bypass owner passwords (e.g., print/edit restrictions); decrypt those first.
Yes — page order is strictly preserved. Inputting “5, 1–3” creates two files: one with page 5, another with pages 1–3 in correct sequence. All formatting, fonts, and links remain intact.
