Frequently Asked Questions
What is Base64 encoding?▼
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to embed images or files directly into HTML or CSS.
Why does the encoded text look longer?▼
Base64 increases the size of the data by approximately 33%, because it uses 4 characters to represent every 3 bytes of binary data.
