Base64 decoder helps you decode Base64 encoded strings back into readable text or original data. This free online tool is useful for developers who work with encoded data in APIs, authentication tokens, or data transmission. Paste your Base64 input, and the decoder will instantly produce the decoded output.
A Base64 decoder converts Base64-encoded data back into its original readable format, such as plain text or binary data.
This Base64 decoder allows you to decode Base64-encoded
strings into their original form. Base64 encoding is commonly used to
safely transmit binary data as text, and decoding is required to retrieve
the original content.
Manually decoding Base64 data can be inconvenient and error-prone.
This tool performs decoding instantly and displays the result in a
readable format.
The decoder automatically handles padding and detects invalid Base64
input.
All decoding happens entirely in your browser for fast performance
and improved privacy. No data is uploaded or stored.
