Our online Base64 validator tool is a useful web application that allows users to validate the correctness of their Base64 encoded data. This tool is particularly valuable for ensuring that encoded content is accurate and error-free. With the Online Base64 Validator Tool, users can quickly determine if their Base64 data follows the correct format.
What is Base64?
Base64 is a method of encoding binary data into ASCII characters to facilitate data transfer and storage.
What is Base64 Validator Tool?
The Base64 Validator Tool is an online utility designed to verify the integrity and accuracy of Base64-encoded data. This tool assists users in confirming whether their Base64-encoded content adheres to the correct formatting and does not contain any errors.
The program is not only capable of interpreting Base64 code, but also recognizes Base64URL and MIME-type Base64 encoded text.
Limitations of the Base64 Validator Tool
Please note that this program only checks that Base64 is syntactically correct, i.e. that the code does not contain any characters that should not occur in Base64 encoded text.
Thus, it may happen that, although Base64 is syntactically correct, it does not contain meaningful data.
How Do I Use the Online Base64 Validator?
- Simply enter the Base64 (or non-Base64) encoded text you want to test in the Input field.
- No need to press the button, the check will run automatically.
- If the input data contains valid Base64 characters, a green feedback will be displayed under Result, otherwise a red notice will be displayed to indicate invalidity.
Is It Secure To Use Your Base64 Validator?
Absolutely. Our program operates entirely on the client side, which means all the conversion processes occur within your browser. No data is sent to our servers, ensuring that your information remains under your control and confidential throughout the conversion process.
Base64 Valid Characters and Table
Uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), and two additional characters, typically “+” and “/”, comprise the set of 64 ASCII characters used in Base64 encoding. When the length of the binary data is not a multiple of three bytes, the “=” character is also used for padding.
Characters in which Base64 and Base64URL differ
Base64 employs a character set that includes special characters such as “+”, “/”, and “=”, which might cause problems in URL situations due to their unique meanings. Base64URL, on the other hand, uses a URL-safe character set by replacing “+” with “-“, “/” with “_”, and omitting padding with “=”.
