Base64 Decode
Decode Base64 text to its original format using different character encodings.
-How Base64 Decode Works
This tool decodes a Base64 string back into its original text format. Simply paste the Base64 string and select the correct character encoding to see the original data.
Practical Usage
Base64 decoding is essential when receiving encoded data from REST APIs or email attachments. Remember that the decoded binary data will be approximately 33% smaller than the Base64 string, as encoding adds overhead for text-safe transmission.
Official Documentation
For more technical details about Base64, consult the official RFC (Request for Comments): RFC 4648: The Base16, Base32, and Base64 Data Encodings.
Facts about Base64 Decode
- Base64 decoding converts ASCII characters back to binary data.
- The process reverses the 33% size increase of encoding.
- Base64 is not encryption and offers no security.
- Padding characters (=) are removed during decoding.
