AnyClip is a browser extension for Chrome, Edge, and Firefox that lets you draw a freehand shape on any webpage and capture whatever is inside that shape as an image. Most screenshot tools constrain you to a rectangle. This one does not. You hold the mouse button, trace any outline you like, bring the cursor back near the starting point, and the extension automatically closes the path and takes the screenshot. After capturing, the extension removes everything outside the shape, leaving the background transparent. The result is saved as a PNG file that looks like a sticker clipped from the page, with a clean edge rather than a bounding box full of extra content. The captured image is automatically downloaded to your computer and also saved to a gallery built into the extension itself. That gallery uses the browser's built-in IndexedDB storage, so the images persist even after you close the browser. From the gallery you can re-download any saved image or delete it. The extension is built to the Manifest V3 standard, which is the current extension format supported by Chrome, Edge, and Firefox. Under the hood it uses an HTML5 Canvas layer to draw the freehand overlay on top of the page, a background service worker to handle the actual screenshot capture and file downloads, and a content script injected into each page to handle mouse input. The popup panel that appears when you click the extension icon shows your saved gallery with hover effects and action buttons. Installation for Chrome and Edge requires loading the folder manually through the browser's developer mode, since the extension has not yet been submitted to the Chrome Web Store. Firefox users can load the included .xpi package file directly through the browser's debugging page. The README is written in Chinese, but the extension works on any webpage regardless of language.
