Frequently Asked Questions
What is the difference between encoding and encryption?
Encoding transforms data into a different format for compatibility or transmission purposes, while encryption scrambles data for security. Encoding is reversible without a key, but encryption requires a decryption key.
When should I use Base64 encoding?
Use Base64 when you need to transmit binary data over text-based protocols like email or JSON APIs. It's commonly used for embedding images in HTML/CSS and storing binary data in text formats.
What is URL encoding used for?
URL encoding converts characters into a format that can be transmitted over the Internet in URLs. Special characters, spaces, and non-ASCII characters are converted to percent-encoded format (%20 for space, etc.).
How do HTML entities work?
HTML entities encode special characters that have meaning in HTML (< for <, & for &, etc.). This prevents browsers from interpreting them as HTML markup and ensures they display correctly.
Is my data safe when using this tool?
Yes! All encoding and decoding operations are performed locally in your browser. Your data never leaves your device and is not sent to any servers, ensuring complete privacy and security.
Understanding Text Encoding
Common Encoding Formats
- • Base64: 64 printable ASCII characters
- • URL Encoding: Percent-encoding for URLs
- • HTML Entities: Safe HTML character representation
- • Hexadecimal: Base-16 number system (0-9, A-F)
- • Unicode Escape: \u notation for Unicode characters
Use Cases
- • Web Development: URL parameters, form data
- • API Integration: JSON data transmission
- • Data Storage: Binary data in text formats
- • Security: Obfuscation and data integrity
- • Compatibility: Cross-system data exchange
Developer Tip: Always choose the right encoding for your use case. Base64 for binary data, URL encoding for query parameters, and HTML entities for user-generated content in web pages. Understanding these formats is essential for secure web development.
