Type (or paste) text on the left. Choose to encode it to Base64 or decode it back to readable text.
Encode text to Base64 or decode Base64 strings back to plain text with our free online Base64 tool. It supports standard Base64 and URL-safe encoding, making it perfect for embedding data in URLs, APIs, emails, and configuration files.
Paste your text or Base64 string into the input panel, select your conversion direction, and click Convert. You can optionally wrap output at a specific line length for easier reading. The result appears instantly and can be copied to your clipboard with one click.
Everything happens locally in your browser — no data is ever sent to a remote server. This is especially important when encoding or decoding sensitive content like API keys or credentials. The tool is completely free, requires no signup, and works offline once loaded.
