A Data URL is a `data:` URI that stores file content directly inside the URL instead of referencing a separate file.

Should I use Base64 every time?

Not always. Plain URL encoding can be shorter for simple text, while Base64 is useful for binary or complex content.

Is the payload private?

Yes. Encoding and decoding run in your browser for this tool.
