Frequently Asked Questions
What is Base64 encoding?
Base64 is an encoding scheme that converts binary data into ASCII text using 64 printable characters. It is commonly used to embed images in HTML/CSS, encode email attachments, and pass data in URLs.
Does Base64 encrypt my data?
No. Base64 is encoding, not encryption. Anyone can decode a Base64 string. Do not use it to protect sensitive information.
Why does Base64 output end with == ?
Base64 pads output with = signs to make the length a multiple of 4. One or two = signs at the end is completely normal.
