PDF Vector Crop - Pro Academic Snipping Tool

PDF Vector Crop makes it easy to crop selected content from PDF pages in Microsoft Edge. Open an online or local PDF, click the extension button, and select a chart, formula, image, text block, or any other page region in the built-in PDF viewer. The selected region can be exported as a cropped PDF that preserves the original content, saved as a high-resolution PNG image, or copied to the clipboard. Smart detection can help locate chart and figure regions automatically, with an adjustable crop margin.

The extension provides both Chinese and English interfaces. All PDF processing takes place locally in the browser, and document content is never uploaded to the developer or any third-party server. To open local PDF files, enable “Allow access to file URLs” on the extension details page. If access is disabled, the extension displays instructions explaining how to enable it.

PDF Vector Crop 用于在 Microsoft Edge 中快速裁剪 PDF 页面内容。打开在线 PDF 或本地 PDF 后，点击扩展按钮进入内置阅读器，即可拖动选择需要的图表、公式、图片或文字区域。所选区域可以导出为保留原始内容的裁剪 PDF，也可以导出为高分辨率 PNG 图片或复制到剪贴板。智能识别功能可以帮助定位页面中的图表区域，并支持调整裁剪边距。

扩展支持中文和英文界面。所有 PDF 处理均在浏览器本地完成，不会将文档内容上传到开发者或第三方服务器。若需要打开本地 PDF，请进入扩展详细信息页面，开启“允许访问文件 URL”；未开启时，扩展会显示相应提示。本扩展适合整理论文插图、课件内容、报告图表，以及其他需要从 PDF 中提取页面区域的场景。
