What is Base64URL?

Base64URL is a variant of the standard Base64 encoding intended for usage in URLs and filenames. It uses a modified character set and replaces characters with special meanings in URLs to offer a URL-safe representation of binary data. When binary data needs to be included in URLs, query parameters, or other components of a web application’s URL structure, Base64URL encoding is widely employed. It ensures that the encoded data is preserved and does not interfere with URL processing or formatting.

What is Base64URL Encoding?

Encoding, in general, refers to the process of converting data from one format to another.

Base64URL Encoding is a method used to transform binary data into a text-based format that is safe to include in URLs and other contexts where special characters might cause issues. Encoding involves converting binary data into a series of characters using a specific character set. In the case of Base64URL, the standard Base64 encoding is modified to use URL-safe characters: the characters ‘+’ and ‘/’ are replaced with ‘-‘ and ‘_’, and any trailing ‘=’ padding is removed.

  4. If you want, you can copy the result using the Copy button.

Is Base64URL an Encryption?

It should be noted that Base64 encoding is not a type of encryption. While it changes the way data is represented, it does not provide security or confidentiality. The goal of Base64 encoding is to ensure data compatibility and to avoid problems with binary data transmission.
