About Comfort
Most online tools for this task bury what you need behind ads and forms. Comfort 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. It is one of about a hundred utility tools that share the same philosophy: do one thing, do it well, get out of your way.
