SingleFile

Save a complete page into a single HTML file

SingleFile is a powerful Chrome extension designed to save complete webpages into a single HTML file. It captures all the elements including CSS, images, fonts, and frames, enabling users to archive or share exact replicas of web content offline.

Users can conveniently save the current page, selected content, frames, or links via the toolbar button or context menu. Advanced features include annotating pages by highlighting text, adding notes, or removing unwanted sections before saving. SingleFile supports batch saving of multiple tabs, and offers auto-save options for tabs upon loading. Integration with Google Drive is available to upload saved pages automatically, and the extension can add proof of existence linking the saved pages' hash to blockchain.

Customizable shortcuts, detailed options, and ongoing development documented on GitHub make this extension a versatile tool for researchers, professionals, and casual users needing reliable offline copies of webpages.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

SingleFile requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that an Edge add-on may turn malicious. This is determined by the publisher and the Edge add-on reputation on Edge Add-on Store, the amount of time the Edge add-on has been around, and other signals about the Edge add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing an Edge add-on.

SingleFile has earned a fairly good reputation and likely can be trusted.
