Base64 encoding converts binary data into ASCII text format. Use it when transmitting binary data over text-based protocols (email, JSON APIs), embedding images in HTML/CSS, or storing binary data in text formats. Remember: Base64 is not encryption!

URL encoding (percent encoding) makes text safe for use in URLs by converting special characters to %XX format. Base64 converts any data into a text format using A-Z, a-z, 0-9, +, and /. Use URL encoding for query parameters and Base64 for binary data transmission.

HTML entity encoding prevents XSS attacks by converting special characters (<, >, &, etc.) into safe entities (&lt;, &gt;, &amp;). Always use it when displaying user-generated content on websites to prevent security vulnerabilities.

JWT (JSON Web Token) is a secure way to transmit information between parties. Our JWT decoder splits the token into its three parts (header, payload, signature) and decodes the header and payload. Note: This tool does not verify signatures - always verify JWTs on your server.
