Frequently asked questions

Is Base64 Encoder free to use?

Yes. Everyday use is free. A free account also saves your history, while watermark-free exports and higher AI limits come with a paid plan.

Do I need to create an account to use Base64 Encoder?

No. You can use it as a guest. Signing in adds saved history, and paid plans add higher AI limits and clean, watermark-free exports.

Is my data kept private?

Text and image tools that can run in your browser do exactly that, so the content never leaves your device. AI tools send your prompt or file to the model provider only to produce the result.
