Local processing, explained plainly.
These tools process the text and files you provide inside your browser, rather than sending them to a Free Online Tools Nest processing server. Large files can still be limited by your device's memory.
The website can make separate requests for fonts, Google Analytics and advertising. Local tool processing does not mean the entire page is disconnected from the internet.
