How it works
Everything happens on your machine
Most converters upload your file to a server. This one doesn't have one.
01<br>You choose a file
It's read straight into your browser's memory — never sent anywhere.
02<br>Your browser converts it
Canvas, PDF and text engines built into the page do the actual work.
03<br>You download the result
Close the tab and it's like it never happened — nothing is stored.
