SingleFile is a Safari extension for macOS that saves complete web pages as a single HTML file for offline viewing and archiving.
What is SingleFile?
SingleFile is a Safari extension for macOS that helps users save a full web page, including images, styles, fonts, and frames, into one HTML file. It is designed for people who want a portable offline copy of online content without relying on screenshots or PDF exports. Common uses include research, reference collecting, recordkeeping, and preserving pages that may change later. Saved pages can keep links and much of the original layout, which makes them easier to revisit in a browser. SingleFile also supports workflows such as saving selected content, annotating saved pages, and handling multiple pages in broader archiving tasks. The Safari edition is distributed for Apple platforms and gives Mac users a focused way to capture web content directly from the browser.

Safety overview
Status: Safe
SingleFile is a legitimate Safari extension used to save web pages for offline access. It needs access to the pages you choose to save, which is normal for this kind of browser tool. Saved pages may include the visible content of the sites you capture, so avoid archiving sensitive account pages or private information unless you intend to keep that data locally. If you stop using it, removing the app only affects this page-saving feature and your existing saved files remain your responsibility to manage.
Recommendation: Keep SingleFile if you regularly save articles, documentation, or reference pages from Safari. If you do not use web-page archiving, you can remove it without affecting macOS beyond losing its save-to-HTML workflow.
