网页截屏

截取网页滚动区域并拼接成一张图片，支持不同分辨率、文件大小上限、保存和剪贴板复制。

Full Page Capture is a high-quality screenshot extension for long web pages. It captures and stitches scrolling content into one or multiple clear images, with support for right/left scroll regions, full page mode, custom screen ranges, and start-end line capture. You can export in PNG, WebP, or JPEG, choose output resolution, and set a target file size limit. To reduce repeated headers and floating overlays, the extension can temporarily hide fixed/sticky elements before capture. For very long pages, Full Page Capture supports auto-split export based on a configurable height threshold (default: 18000 px) to preserve image clarity. All capture, stitching, and export processing runs locally in your browser. No screenshot content is uploaded to external servers.
