About the image to base64
A Base64 data URL embeds an image directly inside your HTML or CSS as text, instead of linking to a separate file. The browser decodes it back into the picture with no extra network request.
This is useful for small icons, logos and email templates, where one fewer request matters or where the file cannot be hosted separately. Base64 makes the data roughly a third larger, so it suits small images rather than photographs.
Your file is read locally by your browser and never uploaded, so even private images stay on your device.
