About Us

Who We Are

3box is a free online‑tools platform built for learners, developers, educators and general‑purpose web users. Our goal is to deliver lightweight, browser‑run utilities that work directly inside your web browser, without mandatory registration, downloads or software installation.

What We Offer

We maintain a growing collection of free web‑based tools covering multiple categories:

• Office & math utilities: standard and scientific online calculator
• Time tools: timestamp converter, world clock and time‑zone map
• Text processing: URL encode/decode, HTML escape, character counter, case converter, ISBN lookup
• Image tools: QR‑code generator & decoder, Base64 conversion, favicon maker, screen dead‑pixel test
• Educational visualization tools: interactive 3D anatomy model and 3D interactive globe

Important note for our 3D anatomy tool: The interactive human‑body anatomy viewer is built purely for educational and reference purposes. It is intended for self‑study for students and educators, and shall not be used for clinical diagnosis or medical decision‑making. It is not a substitute for professional medical advice from qualified healthcare providers.

Our Core Principles

• Browser‑first: Most tools run locally on your device; many operations never send your data to our backend server.
• No mandatory sign‑up: You can use nearly all functions without registering an account.
• Mobile‑friendly: Every tool is optimized for both desktop computers and mobile phones.
• Free for personal use: All core features are available at no cost for non‑commercial personal usage.

Disclaimer Reminder

All tools and visual content are provided on an "as‑is" basis. We do not guarantee absolute accuracy of every output. Please review our Privacy Policy, Terms of Use and dedicated Disclaimer for full details.
