Base64 Encoding Guidelines
- Base64 encoding converts binary data into ASCII text format for safe transmission over text-based protocols.
- Common uses include data URIs, email attachments, and storing binary data in JSON or XML.
- Text encoding works with any text input including URLs, JSON, XML, and plain text.
- File encoding supports various file types including images, documents, and PDFs.
- Output format produces a string containing only ASCII characters (A-Z, a-z, 0-9, +, /, and = for padding).
- Size increase - Base64 encoded data is approximately 33% larger than the original binary data.
- Privacy assurance - all encoding happens in your browser, no data is sent to servers.
Base64 encoding is essential for safely transmitting binary data through text-based systems.
