Is my image uploaded to a server?

No. Conversion runs entirely in your browser — the file never leaves your device.

What image formats are supported?

PNG, JPG, GIF, and WebP files all convert to a valid Base64 data URL.

Why would I embed an image as Base64 instead of linking it?

Base64 data URLs remove the need for a separate image request, which is useful for small icons, emails, or offline HTML files.
