打开 PDFnoted 网站或桌面端,点击「Compare PDFs」按钮;拖拽或选择两个版本的 PDF(如 v1.0 和 v2.0),确保文件未加密且文字可选(非扫描图)。PDFnoted 将自动解析每页文本结构。
点击「Start Comparison」后,PDFnoted 逐页比对文字内容,识别插入、删除、替换等变更类型,并以彩色高亮(绿色=新增,红色=删除,蓝色=修改)直观呈现。左侧为原始版,右侧为新版,支持滚动同步查看。
确认无误后,点击「Export Report」生成 PDF 格式比对报告:含差异摘要页、逐页高亮对比视图、以及变更统计(如共修改 17 处,新增 42 字)。支持一键下载,便于存档或邮件发送给同事审阅。
Go to PDFnoted’s website or desktop app, click ‘Compare PDFs’. Drag & drop or select two PDF versions (e.g., v1.0 and v2.0). Ensure files are not password-protected and contain selectable text (not scanned images). PDFnoted parses text layout page-by-page automatically.
Click ‘Start Comparison’. PDFnoted performs page-by-page textual diff, detecting insertions, deletions, and substitutions. Changes appear color-coded: green = added, red = deleted, blue = modified. Left panel shows original PDF; right panel shows revised version — with synchronized scrolling for easy review.
Once reviewed, click ‘Export Report’ to generate a printable, shareable PDF report — including a summary page, side-by-side annotated pages, and change statistics (e.g., ‘17 edits, 42 words added’). Download instantly for archiving or emailing to collaborators.
不能。PDFnoted 基于文字内容比对,要求 PDF 内含可复制文本(OCR 处理后的扫描件可支持,但需提前在其他工具中完成 OCR 并保存为文本型 PDF)。
是的。PDFnoted 在比对时保留原始页面布局、字体、段落结构;差异高亮叠加在原样式上,不破坏文档专业外观,适合正式场景交付。
当前版本暂不支持手动页码范围筛选,但你可在上传前用 PDFnoted 的「Split PDF」工具提取目标页(如第5–12页),再对子文件执行比对,实现精准聚焦。
No. PDFnoted compares text content directly — it requires searchable, selectable text. Scanned PDFs must first be processed with OCR (e.g., using Adobe Acrobat or online OCR tools) and saved as text-enabled PDFs before use in PDFnoted.
Yes. PDFnoted retains original page layout, fonts, and paragraph structure. Highlighted changes overlay seamlessly on the native design — ensuring professional appearance for contracts, legal docs, or academic submissions.
Direct page-range selection isn’t supported yet. However, you can pre-split your PDFs using PDFnoted’s built-in ‘Split PDF’ tool (e.g., extract pages 5–12), then run comparison only on those segments — enabling targeted, efficient review.
