FAQ
What is a Base64 image?
Base64 encodes an image’s binary data into plain text. As a “Data URL” it can be embedded directly in a page, email or config file without a separate file request.
What is the difference between a Data URL and raw Base64?
A Data URL carries a `data:image/png;base64,` prefix and can be used directly as an img src; raw Base64 is just the encoded content, for cases where only the string is needed.
Are my images uploaded to a server?
No — conversion runs entirely in your browser, so image content never leaves your device.
