Open toolWhy these tools?
Most online utilities upload your text, links and files to a server you can't see. These don't. Every tool here is plain HTML, CSS and JavaScript that executes entirely on your device, so your data never leaves the browser tab.
That also means they're fast, free forever, and keep working even with the network off.
