About Dovetail

Most online tools for this task bury what you need behind ads and forms. Dovetail takes the opposite approach: load the page, do the job, leave. Processing runs locally in your browser using modern Web APIs. Nothing is uploaded, nothing is logged, and there is no quota to worry about for casual use. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.
