Hi everyone! I built Toolzom because most "free tool" sites are slow, full of pop-ups, or quietly send what you paste to their servers.
A few things I cared about:
• Everything runs in your browser — your text, JSON or passwords never leave your device.
• The JSON formatter keeps large numbers exact (most online formatters silently round IDs like 12345678901234567890).
• QR codes are static, so they never expire or depend on my site.
• Passwords and UUIDs (v4 and the newer time-ordered v7) use the browser's cryptographic generator.
• Fully bilingual: every tool and guide also exists in Spanish.
It's free with no account. I'd love to hear which tool you'd like to see next!
