Use our free Base64 decoder to convert Base64 encoded strings back to readable text instantly. This online tool processes everything in your browser, so your data never leaves your device. Perfect for developers who need to decode API responses, read encoded data, or debug Base64 strings.
Base64 is a binary-to-text encoding scheme that represents binary data using 64 ASCII characters. Decoding Base64 reverses this process to retrieve the original text or binary data.
Decode Base64 encoded strings back to readable text instantly. All processing happens in your browser for complete privacy and security.

Base64 decoding converts a Base64 encoded string back to its original form. This tool reverses the encoding process, transforming the 64-character representation back into binary data or text. It's essential for reading encoded data from APIs, emails, or embedded content.
Decode Base64 encoded email attachments and embedded content from MIME format.
Decode Base64 data received from REST APIs and web services for debugging.
Decode JWT token payloads to inspect claims and verify token content.
Base64 decoding is the reverse process of Base64 encoding. It converts a Base64 string back to its original binary or text format using the standard 64-character alphabet.
Yes! All decoding happens entirely in your browser. Your data never leaves your device or gets sent to any server.
Invalid Base64 errors usually occur when the string contains invalid characters, has incorrect padding, or was corrupted during transmission. Ensure the string only contains A-Z, a-z, 0-9, +, /, and = characters.
