What is Base64 Decode?

Base64 Decode is the process of converting Base64-encoded text or data back to its original form. This could be plain text, binary files, images, or other types of data that were encoded for safe transfer or storage.

Importance of Base64 Decode

Base64 encoding is often used to store or send binary data in text-based formats like JSON, HTML, or email. To use the data in its original form, you must decode it. This ensures files, images, and text display or function correctly after transfer.

Can I decode large files?

Yes, but very large Base64 strings may require more processing time or memory.
