Frequently Asked Questions
- What image formats are supported?
- PNG, JPEG, GIF, SVG, WebP, ICO, and BMP. Any image your browser can display will work.
- Is my image uploaded to a server?

- What is a data URI?
- A data URI embeds the image directly in HTML or CSS as a Base64 string, eliminating the need for a separate file request.
