❓ Frequently Asked Questions

What is Base64 encoding used for?

Base64 is commonly used to transmit binary data over text-based protocols like email (MIME), embed images in HTML/CSS as data URIs, and store binary data in JSON or XML without corruption.

Is the encoding done on my device?

Yes. Both encoding and decoding happen entirely in your browser using JavaScript. No data is uploaded to any server, keeping your information completely private.

Can I decode Base64 strings back to original text?

Yes. Any valid Base64 string can be decoded back to its original text. Simply paste the Base64 string, select Decode, and the tool will restore the original content.
