Frequently Asked Questions

What is Base64 encoding?

Base64 is a way to represent binary data using 64 text characters (A-Z, a-z, 0-9, +, /). It lets you safely include images or binary data inside text formats like JSON, HTML and URLs.

Is Base64 encryption?

No. Base64 is encoding, not encryption - anyone can decode it instantly. Never use it to protect passwords or secrets.

Why is my Base64 string so long?

Base64 output is about 33% larger than the input. That overhead is the price of making binary data text-safe.

Can I decode any Base64 string here?

Yes, as long as it is valid Base64. The tool will tell you if the input is not decodable.
