Is there a mobile app or is this web-only? I'd love to have tools on my phone?
Great news ZTools is available on Android too!
Here's where you can use ZTools:
Web App full experience at https://ztools.zaions.com, works on any browser
Android App available on Google Play Store (search "ZTools" by Zaions)
Browser Extension Chrome Web Store ("ZTools - Utility Tools") for quick access from any tab
PWA Support install from the browser for a native-app-like experience
All three surfaces share the same tool library, so you get the full 484 tools whether you're on desktop, mobile, or using the extension. Your favorites and settings sync across devices if you sign in with Google.
What does the browser extension do? Is it just a link to the website?
Definitely not just a link! The extension is built as a standalone quick-access companion:
Instant tool access open the extension popup and use tools directly without navigating to the site
Search from your toolbar find any of the 484 tools right from the extension icon
No new tab needed run quick conversions, formatting, or generation without leaving your current page
Same tool quality uses the same client-side logic as the web app
Chrome & Firefox built for both browsers with a custom build system
It's designed for the "I need this tool for 10 seconds" moments. You're coding, you need to quickly base64-encode a string pop open ZTools, paste, done, back to work. No context switching.
"The fastest tool is the one that's already in your toolbar."
Can I save my most-used tools? I only need about 20 tools regularly.
Absolutely this is exactly what favorites, collections, and presets are for!
Favorites one-click star on any tool to add it to your favorites list for quick access
Collections group related tools together (e.g., "My Dev Tools", "Design Toolkit", "Finance Stuff")
Presets save specific configurations for tools you use repeatedly
History recently used tools are tracked so you can jump back quickly
Cloud Sync sign in with Google and your favorites + collections sync across all your devices
Smart Search even without favorites, search instantly surfaces what you need
For someone who uses 20 tools regularly, I'd suggest:
Star your top 20 as favorites
Create 2-3 collections to group them by workflow
Sign in once to sync everything
I'm a developer — which tools are most useful for coding and debugging work?
Fellow developer here this is literally why I built ZTools in the first place!
Here are the developer favorites:
JSON Formatter/Validator paste messy JSON, get it formatted and validated instantly
Base64 Encoder/Decoder for API tokens, image encoding, data payloads
Color Converter HEX RGB HSL conversions for CSS work
Regex Tester build and test regular expressions with live matching
Minifier/Beautifier JavaScript, CSS, HTML compress or expand
UUID Generator generate v4 UUIDs for database seeding and testing
Hash Generator MD5, SHA-1, SHA-256 for verification workflows
Diff Checker compare two text blocks side by side
URL Encoder/Decoder handle query params and encoded URLs
Lorem Ipsum Generator placeholder content for UI mockups
Timestamp Converter Unix human-readable date/time
Unit Converters bytes, pixels, rem/em, and more
The best part? Everything runs in your browser. No API keys being sent to random servers. No "paste your code here and trust us" situations.
