About Base64Decode.in

Base64Decode.in is a powerful and free web tool that converts Base64-encoded data back into readable text or files. Use it to decode strings, JSON, or even Base64-formatted files with full control over character set and formatting.

Base64 decoding helps restore original binary/text content from encoded data. It's commonly used in APIs, email systems, embedded images, and secure file transfers.
