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.
