FAQ
What is text encoding?
Text encoding is the process of converting text into a specific format for transmission or storage. Common encodings include Base64, URL encoding, HTML entities, and hexadecimal.
What is Base64 encoding used for?
Base64 encoding is used to safely transmit binary data over text-based protocols. It's commonly used for embedding images in CSS, encoding email attachments, and storing complex data in JSON or XML.
Is encoding the same as encryption?
No. Encoding transforms data into a different format using a publicly known scheme, but it's easily reversible. Encryption uses a secret key and is designed to be computationally infeasible to break without the key.
