Everyday tools guide
These are the “use it once, save 10 minutes” tools: quick timers, QR codes, text cleanup, time zones, and size conversions. They’re built to be fast on mobile and easy to copy/share.
Start here
Turn a URL, message, or Wi‑Fi details into a scannable code.
QR Code GeneratorGenerate a professional HTML signature with an optional logo and a plain-text fallback.
- QR codes: shorter content = easier scanning. If a QR looks “busy,” shorten the URL.
- World clocks: focus on overlap hours (for example 09:00–12:00 in each region) rather than exact minutes.
- Clothing sizes: conversions are approximate. Use brand charts for final confirmation.
- Timers: always cool boiled eggs in ice water to stop cooking and improve peelability.
Tool highlights (what they’re best for)
QR Code Generator
QR codes are best when you want a phone camera to “just open” something without typing. Good uses include URLs, contact cards, Wi‑Fi access, or a WhatsApp link.
- URL: a landing page, product page, or document link.
- Wi‑Fi: share network name + password with guests.
- Contact: a vCard for business cards or events.
Egg Timer
Boiled eggs are all about consistent timing. The egg timer helps you adjust by size, starting temperature, and preferred softness.
If your eggs crack in boiling water, start with room-temperature eggs and lower them in gently. Use an ice bath at the end to stop cooking.
Text Case Converter
This is ideal for headlines, filenames, and SEO slugs. It’s also handy when you’ve copied text with weird casing and just need it fixed.
Input: hello world from SMART web apps
Title Case: Hello World From Smart Web Apps
Slug Case: hello-world-from-smart-web-appsClothing Size Converter
Sizes vary by brand, but conversions are still useful when shopping internationally. Use this tool as a starting point, then double-check the brand’s size chart if available.
Privacy note
Most everyday tools don’t send your input anywhere (they run locally). For tools that must call an external endpoint (for example “What’s my IP”), the tool page lists what it calls and why.
