Most online tools for this task bury what you need behind ads and forms. NASA APOD 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. If you find yourself doing this regularly, the rest of the utility suite covers most adjacent tasks with the same approach.
