Encode and decode text using URL encoding, HTML entities, Base64, hex, and binary formats. Free online encoding tool.
Text encoding is the process of converting text from one format to another for various purposes such as data transmission, storage, security, and compatibility. Encoding transforms text into different representations while preserving the original information.
Different encoding formats serve different needs - from making text safe for URLs to representing binary data as text, or ensuring proper display in HTML documents.
Converts special characters to percent-encoded format for safe transmission in URLs. Ensures compatibility across different systems and browsers.
Example: "Hello World!" → "Hello%20World%21"
Converts special characters to HTML entity format for safe display in web pages. Prevents HTML parsing issues and ensures proper rendering.
Example: "<script>" → "<script>"
Converts binary data to ASCII text format using 64 characters. Commonly used for encoding images, files, and binary data in text-based protocols.
Example: "Hello" → "SGVsbG8="
Converts text to base-16 representation using 0-9 and A-F characters. Useful for debugging, binary analysis, and low-level programming.
Example: "Hi" → "4869"
Converts text to base-2 representation using only 0 and 1 characters. Shows the fundamental binary representation of text data.
Example: "A" → "01000001"
URL encoding for query parameters, HTML entities for safe content display, and Base64 for embedding images and files in web applications.
Encoding data for safe transmission across different systems, protocols, and character encodings while maintaining data integrity.
Encoding sensitive data, obfuscating information, and ensuring data can be safely transmitted without corruption or interpretation issues.
Converting data between different systems that use different encoding standards, ensuring compatibility and proper data handling.
Each character is analyzed and converted to its numerical representation
Numbers are converted to the target encoding format (hex, binary, etc.)
Special characters are converted to their encoded equivalents
Final encoded text is generated and displayed
Use URL encoding when you need to include special characters in URLs, query parameters, or form data. This ensures compatibility across all browsers and systems.
Encoding is reversible and meant for format conversion, while encryption is for security and requires a key to decrypt. Encoding doesn't provide security - it's for compatibility.
Yes, you can encode any text data. For binary data like images or files, Base64 encoding is most appropriate as it converts binary to text format.
Not always. Some encodings like hex and binary can be more compact for certain data, while Base64 typically increases size by about 33% due to its 6-bit to 8-bit conversion.
