Why browser-based tools?

Many one-off utility sites ask you to paste sensitive snippets into a server form. Toolora focuses on client-side processing for v1 tools: JSON formatting, encoding, hashing, Markdown preview, and similar utilities run in your browser. That means faster results, fewer round-trips, and a clearer privacy story for everyday work.

Tip: Dark mode is the default. Switch to Light anytime from the palette icon in the header.
