## Basic information - Name: Jiandu Reader — Clean Web Reading - Summary: Turn the current webpage into a clean, fixed-width reading view with typography controls, media modes, editing, and A4 PDF printing. - Category: Productivity - Language: English - Mature content: No ## Detailed description Jiandu Reader turns the webpage you choose to open into a clean, fixed-width reading view designed for focused reading and print-ready PDF export. No account is required. Jiandu Reader uses no cloud service and does not send article content, page URLs, or reading history to the developer. Reading, formatting, and editing are performed locally in your browser. Key features • Reader mode: Extracts the visible title, article content, images, tables, quotes, and code into an independent reading layer without changing the original page. • Focus cleanup: Keeps normal site interactions such as playback, search, sign-in, and comments while reducing distracting app prompts, ads, recommendation blocks, and sidebars. • Fixed reading width: Choose a preset width or a custom width for long articles, technical documentation, tutorials, and news. • Typography controls: Choose common cross-platform, Windows, macOS, and Linux font stacks; adjust font size, line spacing, paragraph spacing, and text alignment. • Outline and progress: Open a table of contents for long articles and follow reading progress. • Media and text modes: Collapse visual media into a clickable picture placeholder or switch to a monospaced plain-text reading mode. • Edit the reading copy: Edit text, remove unwanted blocks, undo, and redo without modifying the original webpage. • Print and PDF: Builds a dedicated A4 print document and normalizes images, SVG, Canvas, and wide diagrams to reduce blank first pages and cropped media. • Local settings: Theme, typography, width, and layout preferences are saved in Chrome Sync storage for use on your Chrome devices. How it works 1. Open an article or content page. 2. Click Jiandu Reader in the browser toolbar and choose Start Reading. 3. Use the right-side reading rail to adjust layout, typography, theme, media mode, or editing. 4. Click the print icon and choose Save to PDF in Chrome's print dialog. Privacy and scope Jiandu Reader processes a page only after you click the extension, use its shortcut, or explicitly enable optional automatic cleanup. It does not bypass paywalls, sign-in requirements, or access controls. It does not sell data, show ads, inject tracking, or upload article content. Compatibility Jiandu Reader uses a general article extractor and includes dedicated adapters for selected content sites. Dynamic single-page apps, video pages, search pages, forum lists, and shopping pages may be better suited to Focus Cleanup or Select Content to Read. 将当前网页转成固定宽度、可定制、适合专注阅读与 A4 PDF 保存的书面阅读视图。 简读将你主动打开的当前网页转换为一个干净、固定宽度、可长期阅读和打印保存的书面阅读视图。 它不需要账户，不使用开发者自建云端服务，也不会把文章内容、网页地址或阅读记录发送给开发者。阅读、排版和编辑均在浏览器本地完成。 主要功能 • 阅读模式：从当前页面提取标题、正文、图片、表格、引用与代码，在独立阅读层中呈现；退出后原网页保持不变。 • 聚焦净化：保留原网站的播放、搜索、登录和评论等交互，同时减少下载 App 引导、广告、推荐与常见侧栏带来的干扰。 • 固定阅读宽度：提供预设宽度与自定义宽度，适合新闻、技术文章、教程与长文阅读。 • 字体与排版：可切换常用跨平台、Windows、macOS、Linux 字体；支持字号、行间距、段落间距和正文对齐调整。 • 目录与进度：长文可打开章节目录并查看阅读进度。 • 无图与纯文本：可将媒体折叠为可点击的 picture 占位，或进入等宽纯文本阅读模式，减少视觉干扰。 • 阅读副本编辑：可在简读副本中修改文字、删除多余内容，并使用撤销和重做；不会修改原网页。 • 打印与 PDF：生成独立 A4 打印文档，处理图片、SVG、Canvas 和宽图，帮助减少网页样式导致的空白页或图片裁切。 • 本地设置：主题、字体、宽度和排版偏好保存在 Chrome 同步存储中，便于在你的 Chrome 设备间沿用。 使用方式 1. 打开一篇文章或内容页面。 2. 点击浏览器工具栏中的“简读”，选择“开始阅读”。 3. 在阅读层右侧调整宽度、字体、主题、无图、纯文本或编辑模式。 4. 点击打印图标，在 Chrome 打印窗口中选择“保存为 PDF”。 权限与隐私 简读仅在你点击扩展、使用快捷键，或主动开启“自动净化”后才处理网页。它不提供绕过付费墙、登录门槛或访问控制的功能；不会出售数据、展示广告、植入追踪或上传文章内容。 兼容性说明 简读对常见文章页使用通用正文识别，并为部分内容站点提供专用适配。动态单页、视频页、搜索页、论坛列表和购物页不一定适合抽成单篇文章；这类页面可使用“聚焦净化”，或先选中文章正文再使用“选中内容阅读”。
