Base64 Decoder

The Base64 Decoder converts Base64-encoded data back into its original format. This tool takes Base64 strings and transforms them back into their original text or binary representation.

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. The Base64 Decoder reverses this process, allowing users to view the original content that was encoded. This is particularly useful for examining the content of Base64 data found in various technical contexts.

Common Uses:

• Decoding Base64-encoded email attachments
• Viewing the content of Base64-encoded data in files or documents
• Decoding Base64 data embedded in HTML/CSS data URIs
• Examining HTTP Basic Authentication credentials
• Extracting information from Base64-encoded JWT tokens
• Converting Base64-encoded binary data back to its original form
• Debugging applications that use Base64 encoding for data transfer
• Analyzing encoded content in security and reverse engineering contexts
