About HEX to Base64 Converter

This tool allows you to convert hexadecimal (HEX) data to Base64 encoded format with various display options. HEX is a common way to represent binary data in a text format using the characters 0-9 and A-F.

Supported HEX input formats:

Plain - Simple uppercase or lowercase hex characters (DEADBEEF or deadbeef)
With Dashes - Pairs separated by dashes (DE-AD-BE-EF)
With 0x Prefix - Each byte has 0x prefix (0xDE 0xAD 0xBE 0xEF)
With Colons - Pairs separated by colons (DE:AD:BE:EF)
With Spaces - Pairs separated by spaces (DE AD BE EF)

Available Base64 output formats:

Standard - Regular Base64 encoding (SGVsbG8gV29ybGQ=)
URL Safe - URL-friendly Base64 where '+' is replaced with '-' and '/' with '_'
With Line Breaks - Base64 with line breaks every 76 characters for better readability
