What browser-based actually buys you
An online tool has no installer, so there is no program to trust, nothing updating in the background, and nothing left on the computer when you close the tab. That matters most on devices you do not control — a work laptop, a shared family computer, a school machine where you cannot install software anyway.
It also means one tool covers every platform. The same page works in Safari on an iPhone, Chrome on a Pixel, Edge on Windows and Firefox on Linux, with no separate version to maintain and none that quietly falls behind.
