I got tired of tools sites that force signups, watermark your files, or upload your photos to some server. So I built BlanzaTools — 14 free tools that run 100% in your browser. Your files never leave your device.
Image Tools
- Image Compressor — shrink JPG, PNG and WebP without visible quality loss
- Image Resizer — exact pixel dimensions for social media and web
Text Tools
- Word Counter — words, characters, sentences, reading time
- Text Case Converter — UPPERCASE, lowercase, Title Case and more
- Lorem Ipsum Generator — placeholder text by paragraphs, words or sentences
Calculators
- Age Calculator — exact age plus next-birthday countdown
- BMI Calculator — metric and imperial units
- Percentage Calculator — X% of Y, reverse percentages, % change
- Unit Converter — length, weight, temperature, data and more
Generators
- Password Generator — strong random passwords, generated locally
- QR Code Generator — free QR codes, download as PNG
- Color Picker — HEX/RGB/HSL converter with shades and palettes
Dev & Time

Everything is vanilla client-side JavaScript — no accounts, no watermarks, no limits. If you try them, I'd genuinely love to hear which tool you'd want next.
