SingleFile for Safari vs Dev Promo Kit

SingleFile is a Safari extension that helps you to save an entire webpage including images, styling, frames, fonts etc. as a single HTML file. Unlike screenshots or PDFs, SingleFile can preserve the original layout, links, etc. It's like having a digital snapshot that you can easily access offline. Getting started Wait until the page is fully loaded. Click on the SingleFile button in the extension toolbar to process and save the page. You can click again on the button to cancel the action when processing a page.
