Reference

Data URIs allow embedding small files directly into web documents using base64 encoding. This technique avoids extra HTTP requests for retrieving external resources, potentially improving page load times. However, large Data URIs can negatively impact performance, so they are typically used for small images, icons, and data files. Data URIs are supported by all modern web browsers and can be used in various contexts where image URLs are accepted.

Calculation

This app does not perform complex calculations. It converts uploaded images into different formats like data URIs, CSS backgrounds, and HTML tags for embedding. The conversion process involves reading the image file, encoding it to base64, and formatting the result according to the selected output option.
