Frequently Asked Questions
What is Base64?
Base64 is an encoding scheme that converts binary data into ASCII characters. It's commonly used to embed images in HTML/CSS, transmit data in JSON APIs, and encode email attachments.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode a Base64 string. Do not use it to secure sensitive data.
Why does Base64 output end with == ?
Base64 uses padding characters (=) to ensure the output length is a multiple of 4. One or two = signs at the end is normal.
