Over the past few weeks I've been building small, free web tools — the kind of thing I always wished existed without the signup wall, the ads, or the tracking.
They're all vanilla HTML/CSS/JS. No frameworks, no accounts, no data collection. Everything runs in your browser.
Here's the full collection:
The Tools
Word Counter — Paste text, get word count, character count, sentence count, and estimated reading time.
JSON Formatter — Paste JSON, get it pretty-printed with syntax highlighting. Shows you exactly where the error is if it's invalid.
Base64 Encoder/Decoder — Encode text, decode strings, handle files and JWTs. Supports URL-safe mode.
QR Code Generator — Paste any text or URL, download the QR code as PNG. No watermarks.
Unit Converter — Length, weight, temperature, speed, area, volume. Instant conversion.
Reaction Time Test — Test your reflexes. Average is 250ms. Can you break 200? Challenge your friends with a shareable link.
Typing Speed Test — How fast can you type? Get your WPM score and challenge friends to beat it.
Color Personality Quiz — 5 quick questions to find out your personality color. Surprisingly addictive.
Why?
Every time I needed a QR code or wanted to format some JSON, I'd land on a site that wanted my email or was plastered with ads. These tools cost nothing to host (Cloudflare Pages free tier) and nothing to use.
