How these tools keep files private
Most online converters upload your file to a server, process it there and send it back. These tools skip that round trip: the page loads the code once, and your browser does the work on your own computer or phone. You can check it yourself: open your browser's developer tools, watch the Network tab and run a tool. Nothing is sent.
That also means there is no queue and no daily limit. Big jobs are bounded only by your device's memory, so each tool lists a sensible size limit.
