Everything you need to know about how Quasar works, what it stores, and who built it.
Yes, completely. There's no free tier, no paid plan, no sign-up. Every tool is free forever.
No. Every tool runs entirely in your browser using JavaScript. Your text, files, and data never leave your device. There is no server-side processing.
No account, no email, no sign-in. Open the site, use the tool, close the tab. That's it.
Yes. After your first visit, Quasar is cached by a service worker. You can use every tool without an internet connection. The app also installs as a PWA on mobile and desktop.
Sessions are saved to your browser's localStorage, entirely on your device. There is no cloud sync. Auto-save keeps your last input per tool, and you can create named saves via the Save button inside any tool. Up to 50 named sessions are stored.
JSON, YAML, XML, CSV, TSV, and SQL INSERT statements. You can convert between any of these, format/validate them, and diff them.
HEX, RGB, HSL, HSV, CMYK, and CSS named colors. Every combination is available: 30 converters total.
Length, weight/mass, volume, area, time, temperature, speed, and data storage. More are planned.
Yes. The layout is responsive and every tool works on small screens. On iOS Safari or Chrome for Android, tap "Add to Home Screen" to install it as a standalone app.
No tracking, no analytics, no cookies, no third-party scripts. The page is purely static HTML, CSS, and JavaScript.
