What is Base64 Encoding?
Base64 is a generic term for a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
Base64 encoding is commonly used to embed binary data (like images or other files) within text-based formats such as HTML, CSS, or email messages, where direct inclusion of binary data is not feasible or could cause data corruption. It ensures that the data remains intact during transmission across systems that might not handle binary data natively.
While Base64 encoding increases the size of the data by approximately 33%, it guarantees data integrity and simplifies data handling in text-oriented environments. It's not encryption; it's merely a different representation of data.
Why use Base64 Encoding?
- Data Integrity: Ensures binary data safely traverses systems that were not designed to handle binary data.
- Embedding Data: Allows embedding of images, fonts, and other files directly into source code or HTML files, reducing HTTP requests.
- Email Attachments: Critical for encoding attachments in email systems, as email protocols primarily handle text.
