About Base64 Decoding
Base64 decoding converts Base64 encoded ASCII characters back to the original binary data or text. This reverses the Base64 encoding process.
Common Uses:
- Email attachments: Decoding MIME encoded files
- Data URLs: Extracting embedded images and files
- API responses: Decoding encoded data payloads
- Configuration: Reading encoded settings and credentials
- Debugging: Inspecting encoded data
Input Format:
- Characters: A-Z, a-z, 0-9, +, / (and = for padding)
- Line breaks: Automatically handled and ignored
- Whitespace: Spaces and tabs are ignored
- Padding: = characters at the end for proper alignment
Note: Invalid Base64 characters will cause a decoding error. Ensure your input contains only valid Base64 characters.
