I stopped Googling for simple tools and built my own. Here are 5 I use daily — all free, no install, 100% browser-based.
1. JSON Formatter & Validator
When an API returns a wall of minified JSON, I paste it in, hit format, and instantly see the structure. Catches syntax errors too.
🔗 json-formatter
2. Base64 Encoder/Decoder
Debugging JWTs, reading encoded configs, or embedding images in CSS — one click does it.
🔗 base64-tool
3. UUID Generator
Need a unique ID for a database row, test data, or tracking code? Generates in bulk too.
🔗 uuid-generator
4. QR Code Generator
Sharing links in presentations or print materials? Generates clean QR codes instantly.
🔗 qrcode-tool
5. Text Diff Checker
Comparing config files, code versions, or logs — line-by-line diff with highlighting.
🔗 text-diff
All 14 tools at pyfile-toolkit.github.io/web-toolkit
No ads. No tracking. No accounts. Just tools that work.
