What Is String Encoder/Decoder?
Encode and decode strings with Base64, URL encoding, HTML entities, and more.
String encoding converts characters into a specific format for safe transmission across different systems. Base64 encodes binary data as ASCII text, URL encoding replaces unsafe characters with percent-encoded equivalents, and HTML entity encoding prevents XSS attacks by escaping special characters. Each format serves a specific purpose in web development and data interchange.

Frequently Asked Questions
What is Base64 encoding?
Base64 is an encoding scheme that converts binary data into a text format using 64 ASCII characters (A-Z, a-z, 0-9, +, /). It is commonly used to embed images in HTML, transmit binary data in JSON APIs, and encode email attachments.
What is URL encoding?
URL encoding (also called percent-encoding) replaces unsafe characters in URLs with a percent sign followed by two hexadecimal digits. For example, a space becomes %20 and an ampersand becomes %26. This ensures URLs are valid and unambiguous.
