❓ Frequently Asked Questions
What is Base64 Encoding?
Base64 is a method used to encode text and binary data into readable ASCII text format. It is commonly used in APIs, email systems, authentication tokens, and web applications.
Where is Base64 used?
Base64 encoding is widely used for secure data transfer, image embedding, JWT tokens, API authentication, and storing binary data safely inside text-based systems.
How do I use this tool?
Enter plain text in the box above to convert it into Base64 format, or paste a Base64 encoded string to decode it instantly into readable text.
Is Base64 encryption?
No. Base64 is an encoding scheme, not encryption — it does not provide security or confidentiality. Anyone can decode a Base64 string back to its original form. Use proper encryption for sensitive data.
