LittleJobz is a growing collection of 23 free online calculators and tools spanning 9 categories — from loans and mortgages to calories, grades, and image compression. Our goal is simple: answer the small, practical questions people search for every day, instantly and without friction.
What makes us different
- No signup, ever.Every tool works immediately. No account, no email wall, no “export requires login.”
- Privacy-first.Our calculators run in your browser. Tools like the image compressor process your files entirely on your device — they’re never uploaded to a server.
- Fast and clean. Lightweight pages, no clutter, mobile-friendly, and instant results as you type.
- Clear methodology. Each tool explains the formula it uses so you can trust — and check — the result.
How we keep tools accurate
Every calculator is based on a published, well-established formula (for example, the Mifflin-St Jeor equation for calorie needs, or standard amortization math for loans). We document the method on each tool’s page and review the logic when tax brackets, rates, or standards change. Where results are estimates — like tax or affordability — we say so clearly.
A note on what we are not
Our tools are for information and education. They are not financial, medical, legal, or tax advice. For decisions that matter, please consult a qualified professional. See our disclaimer for details.
