Tiny tools, zero friction.
25 utilities · free forever · client-side
TinyToolkit was born from a simple frustration: every time you need to format JSON, crop an image, or generate a QR code, you end up on a different ad-cluttered website that uploads your data to some server you don't trust. We thought — what if all those tiny daily tools lived in one place, ran entirely in your browser, and never sent a single byte of your data anywhere?
Our Mission
To provide a fast, private, and beautifully designed collection of everyday utility tools that work offline, require no sign-up, and respect your data. Whether you're a developer formatting JSON, a student calculating BMI, a designer picking colors, or a writer counting words — TinyToolkit has you covered without compromising your privacy.
What Makes Us Different
Your data never leaves your device. All processing happens in your browser.
Install as a PWA and use every tool without an internet connection.
No spinners, no waiting. Tools load in milliseconds and respond instantly.
The Tool Library
TinyToolkit currently includes 25 built-in tools across four categories:
- Math & Logic (7 tools) — Standard and Scientific Calculators, Random Number Generators, Name Picker, BMI Calculator, Age Calculator
- Time & Data (3 tools) — Interactive Calendar with notes, CSV Graph Generator, Pomodoro Timer with ambient sounds
- Image & Media (6 tools) — Image Cropper, Image Editor, Color Picker, Image Format Converter, Image Compressor, CSS Gradient Generator
- Text & Dev (9 tools) — JSON Formatter, Base64 Encoder, Password Generator, Word Counter, QR Code Generator, UUID Generator, Hash Generator, URL Encoder, Case Converter
Built With Modern Tech
TinyToolkit is built with Next.js, TypeScript, Tailwind CSS, and shadcn/ui components. The Pomodoro Timer's ambient sounds are powered by the Web Audio API. Image tools use the HTML5 Canvas API. All audio and image processing happens locally — no server compute required. This keeps our hosting costs at $0, which means we can keep the service free forever.
Support the Project
TinyToolkit is free to use and always will be. We support the project through non-intrusive Google AdSense advertisements that are lazy-loaded so they don't slow down your experience. If you find TinyToolkit useful, the best way to support us is to:
- Bookmark the page and use it daily
- Share it with friends and colleagues
