Should I use Base64 for every image?

No. Base64 makes the image about 33% larger. Use it for icons and small images, where saving an extra download is worth it.

Is the image uploaded to a server?

No. The conversion happens in your browser.

Turn an image into Base64 text to place directly in HTML, CSS or emails, with no separate file.
