  3. Paste it into an <img src="…"> or a CSS background.

Frequently asked questions

What is a Base64 data URL?

The image file encoded as text (data:image/png;base64,…) so it can live inside HTML or CSS instead of a separate file.

When should I embed an image?

Only for small images like icons and logos — Base64 is about 33% larger than the file, so big photos should stay as files.

Is my image uploaded?

No — conversion happens locally in your browser with FileReader.

Can I use it for any image type?

Yes — PNG, JPG, WebP and GIF all convert, keeping their original format in the data URL.
