Contact Base64 Tools

You can email the operator about a broken conversion, an incorrect explanation, a privacy question or general feedback.

The website itself has no contact form. Selecting the email link opens your email service, and any message you choose to send is handled outside the browser-only tools on this site.

Before you email

Please do not send passwords, API keys, private keys, access tokens, session cookies, recovery codes, payment information, sensitive Base64 content, or confidential or protected files. Include only the minimum information needed to explain the issue. If a short, non-sensitive sample is necessary, create a safe test case instead of sending real protected data.
