# SHRTX Web Utilities
> Fast, private, browser-based web utilities for developers, designers, and daily digital workflows. Built with a local-first architecture ensuring zero server uploads, instant execution, and complete privacy.

## Overview
SHRTX (shrtx.in) is a modern browser-native utility platform. Every utility executes directly inside the user's browser session using native Web APIs (HTML5 File APIs, Canvas 2D, Web Workers, and WebAssembly). User files, documents, text, images, and data payloads are never uploaded, transmitted, or stored on external servers.

- **Platform URL**: https://shrtx.in
- **Platform Architecture**: Static Astro v5 + React 19 Client Islands + Cloudflare Pages & Workers
- **Execution Model**: Local-First, Client-Side Only (Zero Server Payloads)
- **Privacy Model**: Zero user data retention, zero file transmission
