Frequently Asked Questions

What is Base64 encoding used for?

Base64 encoding is commonly used to embed binary data (like images) in text-based formats such as HTML, CSS, JSON, and email. It converts binary data into a safe ASCII string.

Is my data sent to a server when encoding?

No. All encoding and decoding happens entirely in your browser using JavaScript. Your data never leaves your device.

Can I convert images to Base64?

Yes, our tool supports image to Base64 conversion. Switch to Image Mode, drag and drop your image file, and it will generate the complete data URI for you.

Is Base64 a secure encryption method?

No, Base64 is an encoding format, not an encryption method. It provides no security or obfuscation. It is simply a way to represent binary data as plain text.
