<div class="bg-white p-3 rounded-lg shadow-sm">
<h4 class="font-medium text-blue-600 mb-1">Base64</h4>
<p>Encodes binary data to ASCII characters using 64 different characters (A-Z, a-z, 0-9, +, /). Commonly used for email attachments and embedding images in HTML.</p>
</div>
<div class="bg-white p-3 rounded-lg shadow-sm">
<h4 class="font-medium text-blue-600 mb-1">Base32</h4>
<p>Similar to Base64 but uses 32 different characters (A-Z, 2-7). More human-readable and case-insensitive, often used in OTP tokens and file hashes.</p>
</div>
<div class="bg-white p-3 rounded-lg shadow-sm">
<h4 class="font-medium text-blue-600 mb-1">URL Encoding</h4>
<p>Replaces unsafe ASCII characters with "%" followed by hexadecimal digits. Used in URLs to encode special characters.</p>
</div>
<div class="bg-white p-3 rounded-lg shadow-sm">
<h4 class="font-medium text-blue-600 mb-1">HTML Entities</h4>
<p>Represents special characters in HTML using entity references (like &nbsp; or &#169;). Essential for displaying reserved characters (<, >, &, etc.) and special symbols in web pages.</p>
