SingleFile is a powerful browser extension designed to save complete web pages into a single, self-contained HTML file. Unlike standard saving methods, it captures all essential elements, including CSS, images, fonts, and frames, ensuring the page looks exactly as it did when saved. Users can utilize the context menu to save specific tabs, selected content, or even entire sets of unpinned tabs. Advanced features include an annotation tool for highlighting text and adding notes, as well as the ability to upload saved files directly to cloud services like Google Drive, Dropbox, or GitHub. It even offers a unique way to prove page existence by linking SHA256 hashes to the blockchain.
