Base64 Encoder/Decoder
Encode UTF-8 text or decode standard Base64 into UTF-8 text. Base64 is an encoding, not encryption; binary files are not supported.
About the Base64 Encoder/Decoder
The Base64 Encoder/Decoder lets you quickly encode UTF-8 text into standard Base64 or decode Base64 back into readable UTF-8 text. Enter your text or Base64 value, choose the operation, and get the result directly in your browser.
Base64 is commonly used to represent data using a set of ASCII characters, making it useful when text or data needs to be transferred through systems designed to handle text safely.
This tool works with UTF-8 text. It does not support encoding or decoding binary files.
How to Encode Text to Base64
To encode text, enter the text you want to convert and select Encode.
For example, entering:
Hello World
produces:
SGVsbG8gV29ybGQ=
The resulting Base64 string represents the original UTF-8 text in Base64 format.
How to Decode Base64
To decode a Base64 value, enter a valid standard Base64 string and select Decode.
For example:
SGVsbG8gV29ybGQ=
decodes to:
Hello World
This can be useful when inspecting Base64-encoded text found in APIs, application data, configuration values or other text-based formats.
What Is Base64?
Base64 is a binary-to-text encoding scheme that represents data using a limited set of printable ASCII characters. Its character set consists primarily of uppercase and lowercase letters, numbers, + and /, with = commonly used for padding.
Base64 makes data easier to represent in environments that expect text, but the encoded result is generally larger than the original data.
Most importantly, Base64 is encoding, not encryption. It does not provide secrecy or security. Anyone who has a Base64-encoded value can generally decode it without a password or secret key.
Common Uses for Base64 Encoding
Base64 is frequently encountered in web development, APIs, data formats and software applications. Developers may use or encounter Base64 when transferring data through text-based systems, working with encoded values in API responses, or inspecting application data.
Because Base64 is easily reversible, it should not be used as a method for protecting passwords, confidential information or other sensitive data.
Frequently Asked Questions
Is Base64 encryption?
No. Base64 is an encoding format, not an encryption method. It transforms data into another representation but does not make the original information secret or secure.
How do I encode text to Base64?
Enter your text into the Base64 Encoder/Decoder, select Encode, and the tool will convert the UTF-8 text into its standard Base64 representation.
How do I decode Base64 to text?
Enter a valid Base64 string, select Decode, and the tool will convert it back into UTF-8 text when the encoded data represents valid UTF-8 text.
Why does Base64 sometimes end with an equals sign?
The = character can be added as padding at the end of a standard Base64 value when necessary to complete the encoded output. Depending on the original input length, a Base64 string may have no padding, one =, or two = characters.
Can I encode files with this Base64 tool?
No. This WebToola utility is designed for UTF-8 text and standard Base64 text. Binary file encoding and decoding are not supported.
Does WebToola store the text I enter?
No. The Base64 Encoder/Decoder runs in your browser and does not send or save the text you enter.
