Frequently asked questions about Base64
What is Base64 encoding?
Base64 turns binary data into plain ASCII text using 64 safe characters. This lets files and images travel through systems that only accept text, such as email and URLs.
Is Base64 encryption?
No. Base64 is an encoding, not encryption — anyone can decode it instantly. Never use it to protect passwords or sensitive data; use proper encryption instead.
Where is Base64 used in practice?
Common uses include inline data URLs for images in CSS and HTML, encoding email attachments, embedding small files in JSON, and passing binary data in API tokens.
