Overview
What Is a Base64 Encoder/Decoder?
This tool converts text to Base64 encoding (a common method for representing binary data as text) and can decode Base64 back into readable text.
Encode or decode Base64 text instantly.
This tool converts text to Base64 encoding (a common method for representing binary data as text) and can decode Base64 back into readable text.
Useful for encoding data for transmission in text-based formats or decoding Base64-encoded content.
Type or paste the content to encode or decode.
Encoded or decoded output updates automatically.
A method of encoding binary data as ASCII text characters, commonly used for safely transmitting data in text-only environments.
It allows binary data (like images) to be safely embedded within text-based formats like JSON, XML, or email.
No, Base64 is encoding (reversible, not secret) - it's not a security or encryption method, just a data representation format.
No, all processing happens locally in your browser.
Uppercase and lowercase letters, digits, and the symbols + and /, with = used for padding.
Yes, Base64 is commonly used in web development for embedding images, API data transmission, and various encoding needs.
Yes, any text or binary data can be encoded into Base64 format.
Yes, completely free with no sign-up required.
Yes, Base64 encoding typically increases data size by approximately 33% compared to the original.
Valid Base64-encoded text can always be decoded back to its original form - invalid or corrupted Base64 will show an error.
