About this site
This site is a growing collection of free online tools — calculators, converters, generators and text utilities — built around one rule: your data stays on your device.
How the tools work
Every tool on this site runs entirely in your browser. When you count words, convert an image or calculate a loan installment, the processing happens on your computer or phone — the text you paste and the files you drop are never uploaded to any server. You can load a tool page, disconnect from the internet, and keep working.
That design choice is why the tools are fast, why they work offline, and why we can honestly say we cannot read your data: it never reaches us.
Two languages, one quality bar
Everything exists in English and Serbian — not machine-translated, but written separately for each language, with local details where they matter: VAT rates with their legal source, Serbian alphabet ordering in the line sorter, đ→dj in the slug generator.
We would rather publish ten tools that are genuinely finished than a hundred stubs. Each tool ships with worked examples, an honest FAQ that includes its limitations, and automated tests behind the logic.
What is coming
The collection grows category by category. When a category appears here, the goal is for it to be the most complete resource of its kind in the region — first in Serbian and English, later in more languages.
