Base64 encode, Base64 decode, and Base64 to text
This Base64 tool encodes readable text into Base64 and decodes Base64 back to text. It matches common searches such as Base64 encode, Base64 decode, Base64 to text, and text to Base64.
Base64 is useful for APIs, data transport, configuration values, and debugging. It is not encryption, so decoded content should not be treated as protected.
Formula or logic
- Encode: UTF-8 text bytes → Base64 string
- Decode: Base64 string → UTF-8 text
- Base64 commonly uses A-Z, a-z, 0-9, +, /, and = padding
Example
For example, encoding hello gives aGVsbG8=. Decoding aGVsbG8= returns hello.
Common questions
Is Base64 encryption?
No. Base64 is an encoding format, not encryption.
Why does Base64 decoding fail?
The input may be incomplete, have invalid characters, or include unwanted spaces.
Can it handle non-English text?
Yes. The tool handles UTF-8 text, including Chinese and other languages.
