Frequently Asked Questions
When should I use Base64 encoding?
Base64 is used when you need to encode binary data as text, such as embedding images in HTML/CSS, encoding data in URLs, or transmitting binary data over text-based protocols.
Is Base64 encryption?
No, Base64 is not encryption. It's an encoding scheme that makes data safe for text transmission. Anyone can decode Base64, so it should not be used for secure data transmission.
What is URL-safe Base64?
