Free Online Tools to Simplify Your Life

Private by Design

Powerful, free online utility tools that run in your local browser. No installations and no file uploads — your files and text stay on your device. The few tools that rely on an online service, such as sharing an encrypted paste or looking up a domain, say so on their own page.
