## Overview
Perform string transformations, Base64/Hex/URL encodings, case transformations, and typography analysis without sending raw text across the internet. Built for developers, security analysts, and technical writers.

## Format Specifications
- **Category:** Text & Encodings
- **Supported Formats:** `Base64`, `Hex`, `URL`, `HTML`, `Markdown`
- **Privacy Guarantee:** 0 bytes uploaded to remote servers. All computation executes locally in browser memory.
- **Compliance:** GDPR, HIPAA & SOC 2 Friendly (process sensitive payloads and PII directly on your local device).

## Technology Stack
- Web Crypto API
- TextEncoder / TextDecoder
- Unicode Normalization Engine
- RegEx Parsers

## How It Works
1. Input text streams directly into JavaScript memory without touching network sockets.
2. Encoding transformations use native standard TextEncoder and TextDecoder UTF-8 buffers.
3. Real-time statistics (byte lengths, character counts, reading time) compute reactively on input changes.
4. One-click clipboard export provides instant copying without tracking event telemetry.

## Practical Use Cases
### API & Secret Token Debugging
Encode or decode Base64 strings, Basic Auth headers, and Hex payloads without risking credential leaks to online loggers.

### Programming Identifier Formatting
Convert variable naming between camelCase, snake_case, PascalCase, kebab-case, and CONSTANT_CASE instantly.

### URL Parameter Sanitization
Encode query strings, redirect targets, and deep links to prevent URL parsing errors in web services.

### Copywriting & Technical Documentation
Strip whitespace, calculate reading metrics, and standardize title capitalization for technical articles.

## Frequently Asked Questions
### Is it safe to paste confidential passwords or private API keys here?
Yes. Privatools runs 100% clientside. You can even turn off your network connection before pasting confidential keys to verify that zero traffic leaves your machine.

### Does Base64 conversion support binary UTF-8 characters and emoji?
Yes. Unlike standard atob/btoa functions which fail on multi-byte characters, our engine uses UTF-8 byte array buffers to correctly preserve all international Unicode characters and emojis.

### Can I process large files through this text tool?
Yes, inputs up to several megabytes of text are parsed and transformed in milliseconds.
