Detecting...Our Base64 Encode/Converter tool provides a simple yet powerful way to encode and decode data in Base64 format. Base64 encoding is commonly used for transmitting data over media that are designed to deal with textual data, ensuring that the data remains intact without modification during transport.
Use the "URL Safe" feature when you need to include Base64 data in URLs or filenames. This replaces the + and / characters with - and _ respectively, making them safe for URL usage.
