Question 1

What image formats are supported?

Accepted Answer

The tool supports all common image formats: PNG, JPG/JPEG, GIF, WebP, SVG, BMP, and ICO. The output Data URI preserves the original MIME type (e.g., data:image/png;base64,...).

Question 2

Is my image uploaded to a server?

Accepted Answer

No. All encoding happens locally in your browser using the FileReader API. Your image is never uploaded to any server, keeping your data private.

Question 3

What is a Data URI?

Accepted Answer

A Data URI (or Data URL) embeds the image directly as Base64 text in the format data:image/png;base64,iVBORw0.... This allows you to include images directly in HTML, CSS, or JS without separate HTTP requests.
