Free base64 decode and encode tool

Base64 decode turns coded strings back into plain text you can read and edit. Developers see Base64 in APIs, env files, and data URLs when binary data must travel as text.

Paste a Base64 string to decode, or paste plain text to encode. Copy the output in one click. The tool runs in your browser so secrets never leave your device.

Use base64 decode when a log, config, or email attachment shows a long coded block. Encode when a form rejects special characters or you need a quick data-URL style string.

When do I need a base64 decode step?

When an API, config file, or data URL gives you a Base64 string and you want to read the text inside.

Does this base64 decode tool upload my text?

No. Encode and decode run in your browser. Nothing is sent to a server.
