FAQ

Does Base64 encryption protect data?

No. Base64 is an encoding, not encryption. This tool does not upload your text.

Base64 Encode and Decode: Can I use the result in production?

Treat generated, converted, or inspected output as a development aid. Validate security-sensitive values, commands, and configuration in the target environment before production use.

Does Base64 Encode and Decode upload my input?

TrueFree Tools processes the input in your browser and does not store it on our servers. Features that need browser permissions or access to a user-supplied address still follow the notice shown in the tool.
