Hey Product Hunt! 👋
I'm excited to share **Webutilbox** with you today!
Like many of you, my browser tabs are constantly filled with random utility sites. Need to format a JSON blob? Open a tab. Need to generate a secure password, test a regex, or crop an image? Open another.
But I noticed three major issues with most online tools:
1. **Privacy Concerns:** They require you to upload sensitive data (like API keys, JSON payloads, or text) to their servers.
2. **Bloat and Ads:** They are covered in pop-ups, trackers, cookie consent banners, and slow scripts.
3. **Paywalls:** Simple utilities often lock features behind registration or "pro" tiers.
I built **Webutilbox** to solve all of this. It’s a 100% free, lightweight, privacy-focused toolkit of 94+ single-purpose utilities.
### Key Highlights:
- 🔒 **Zero Server Uploads:** Everything is processed 100% locally in your browser using modern web APIs (Web Cryptography, Canvas, Web Audio, File API). Your data never leaves your device.
- ⚡ **Lightning Fast:** Built with Astro JS and vanilla JavaScript. No heavy JS frameworks, tracking libraries, or ads. It loads instantly.
- 📶 **Works Offline:** Once you visit a tool's page, it works even when you're completely disconnected.
- 🎨 **Modern UX:** Clean, cohesive interface with instant copy-to-clipboard buttons and smart developer options.
### What's inside the box? (94+ Tools)
- **Developer utilities:** JSON Formatter, JWT Decoder, SQL Formatter, Regex Tester, JS Obfuscator, Markdown to HTML.
- **Crypto & Security:** SHA-256/MD5 Hashers, Password Generator, Text Encryption, Base64 & Hex Converters.
- **CSS Helpers:** Flexbox/Grid Generators, CSS Gradient/Shadow tools, Border Radius creator.
- **Media & Audio:** Audio Trimmer/Speed Changer, Audio Visualizer, Image Compressor/Resizer, GIF Maker, PDF Merger/Splitter.
- **Quick Calculators:** Investment, Loan, Crypto Profit, Percentage, Compound Interest.
Webutilbox is completely free, with no signup or hidden tiers. I’d love to hear your feedback—which tools do you find yourself using the most, and what utilities should we add next?
