base64 to text decoder

Decode any Base64-encoded string back into readable plain text instantly.

Base64 to Text Decoder reverses the Base64 encoding process, transforming encoded strings back into their original human-readable form. Base64 encoding is commonly encountered in email attachments, API responses, data URIs, JWT tokens, and configuration files where binary or text data has been encoded for safe transport.

This tool is particularly useful for developers inspecting API payloads, decoding JWT token segments, reading encoded configuration values, or simply reversing Base64 strings found in source code and documentation. It saves time compared to writing custom decoding scripts or searching for command-line solutions.

The decoder fully supports UTF-8 encoded content, correctly handling special characters, accented letters, and multibyte characters that were properly encoded. Simply paste your Base64 string, click decode, and view the original text instantly. Invalid Base64 input is caught with a clear error message.

All decoding happens entirely in your browser — no data leaves your device, ensuring complete privacy and security. The tool is free to use, works on all devices, and requires no sign-up, installation, or configuration.
