About SAFBOX UTI

SAFBOX UTI is a collection of free tools for everyday tasks: converting units, colors and images, compressing files for email, creating passwords and QR codes, counting words, and calculating BMI, percentages, loans and savings.

Built on one rule: your data stays with you

Most online tools work by uploading what you give them to a server. That means your text, files and photos are copied to a computer you do not control, where they may be logged, analysed or leaked. Every tool on this site does its work with code that runs inside your own browser. Nothing you type, paste or choose is sent to us or to anyone else.

This is enforced technically, not just promised. Each page is served with a strict Content Security Policy that forbids the tools from connecting to other servers, and the site uses no analytics or tracking scripts. You can verify it yourself: load a tool, switch off your internet connection, and it keeps working.

Safe to use

• No downloads or installers: there is nothing to install that could carry malware. The optional app is the same website saved to your device by your browser.
• No accounts, no sign‑up, no email address required.
• Encrypted connections (HTTPS) on every page.
• Open, readable code with no third‑party libraries loaded from other sites.

How the site is funded

The tools are free. In the future some pages may show advertising, which will be kept separate from the tools and will never have access to what you enter in them.
