Free Online Full Page Screenshot (Chrome Extension) - ATools
Free online full page/long screenshot for any webpage (requires ATools Chrome extension). Runs locally in your browser.
Free online full page screenshot tool (Chrome extension edition). Due to same-origin and browser security restrictions, a normal web page cannot reliably capture external websites by URL. With the ATools Chrome extension, you can open the side panel on the current tab, scroll-and-capture in segments, stitch into a single PNG, and download it for archiving, documentation, QA and bug reports.
Why does this need an extension?
Because of same-origin and browser security restrictions, a normal website cannot read/render arbitrary external pages, so “capture by URL” is not reliable on the web. A Chrome extension can capture the current tab while scrolling and then stitch the result.
How to use
- Install the ATools Chrome extension (load unpacked from the repo before it’s published).
- Open ATools side panel on the page you want to capture.
- Click Start under “Long Screenshot (Current Tab)” and download the PNG.
开发者安装（加载已解压扩展）
在仓库 `site/extension` 目录作为扩展根目录，打开 `chrome://extensions` → 开启开发者模式 → 「加载已解压的扩展程序」→ 选择 `site/extension`。
Tip
Some sites use lazy-loading or fixed headers which can affect stitching. Increase the “scroll delay” or scroll once manually to preload content.
