What is Base64 Decoding?
Base64 decoding converts a Base64-encoded string back to its original binary or text format. It’s commonly used to retrieve data embedded in text-based systems like JSON, XML, or email.
Why Use Base64 Decoding?
- Retrieve images, audio, or video embedded in HTML/CSS.
- Extract binary data from text-only systems.
- Access configuration files or documents stored in databases.
Base64 Example
Encoded: SGVsbG8=
Decoded: Hello
Advantages & Limitations
Base64 decoding is straightforward but requires valid Base64 input. Invalid strings will fail to decode. For large files, direct binary access is more efficient.
Common Uses
- Decoding email attachments (MIME format).
- Extracting images/icons from web pages.
- Retrieving cryptographic keys/certificates.
Tip: Ensure your Base64 string is valid to avoid errors. Encode a file or text to Base64 here.
