About Utility Tools

From generating QR codes and barcodes to crafting strong passwords, encoding data and validating JSON, these utilities cover the small everyday tasks that would otherwise need a dedicated app or website.

Each tool works instantly, directly in your browser, and free — with no registration, no pricing tiers and nothing sent to a server.

Frequently Asked Questions

Do these utilities cost anything?

No - QR generation, password tools, JSON formatting, Base64, hashing and the rest are completely free with no signup, rate limits or premium tiers.

Is sensitive data safe here?

Tools that touch sensitive input - password generators, hash generators, JWT decoding, JSON formatting - run entirely client-side. Your data never reaches a server, which you can verify via your browser's network tab.

Can I use these utilities offline?

Mostly yes. Once a tool page has loaded, processing happens locally, so formatting, generating and converting continue working without connectivity.

Is there a mobile-friendly version?

Every utility is responsive by design and works in modern mobile browsers - scan QR codes with your phone camera, generate passwords on the go, or unzip attachments directly.
