About Base64 Encoding
Base64 is an encoding scheme that converts binary data into ASCII text. It's commonly used in web development, email attachments, and APIs to safely transmit binary data through text-based channels.
Our Base64 tool handles both encoding (text to Base64) and decoding (Base64 to text). It properly handles UTF-8 characters, ensuring special characters and non-English text convert correctly.
The URL-safe option modifies the encoding to use characters safe for URLs, replacing + with - and / with _. This is essential when Base64 data needs to be included in web addresses or query strings.
Developers frequently use Base64 for basic authentication headers, data URIs for inline images, and encoding JSON payloads for transmission. This tool makes testing and debugging these encodings quick and easy.
