Our free online encoding tool allows you to quickly convert between different encoding formats commonly used in web development. Whether you need to encode sensitive data in URLs, convert binary data to Base64, or properly escape HTML entities, this tool has you covered.
Encoding and decoding are essential techniques in web development for data transmission, security, and proper content rendering. Use this tool to:
Base64 encoding is commonly used to encode binary data (like images) into ASCII characters for safe transmission over text-based protocols. It's widely used in web development for data URLs, email attachments, and basic obfuscation.
URI encoding (also called URL encoding) converts special characters in URLs to a format that can be transmitted over the internet. Spaces become %20, slashes become %2F, etc. This prevents URL interpretation errors.
HTML encoding replaces special characters with their HTML entities to prevent XSS attacks and ensure proper rendering. For example, < becomes < and > becomes > to prevent HTML tag interpretation.
All encoding performed by this tool happens directly in your browser - no data is sent to our servers, ensuring complete privacy for your sensitive information.
