Turn Base64 back into readable data.
Paste Base64-encoded text and decode it while debugging APIs, authentication flows, configuration, encoded payloads, and application data.
Decode text quickly
Convert Base64 strings back into their decoded text representation.
Useful for developer workflows
Inspect encoded values found in APIs, configuration, headers, logs, and other application data.
Keep encoded data local
Your Base64 input is processed on your device instead of being submitted to an online decoder.
From Base64 to text
Encoded input goes in; the original text comes out.

Hello, DevT Pro!
When a Base64 Decoder is useful
API development
Inspect Base64-encoded values found in API requests, responses, or integration data.
Debugging application data
Quickly decode strings found in logs, configuration, database values, or development output.
Authentication and headers
Inspect Base64-encoded values encountered while debugging authentication and HTTP-related workflows.
Encoded doesn't mean non-sensitive.
Base64 is an encoding, not encryption. Encoded strings can still represent credentials, internal application data, identifiers, or other information you may not want to send to an external website. DevT Pro decodes them locally.
