Frequently asked questions
What is a data URI?
A string starting with data:image/… that embeds the whole image, so it can be placed directly in CSS, HTML or JSON without a separate file.
When should I use Base64 images?
For tiny icons and placeholders. Large images are better served as files because Base64 is about 33% bigger.
Can I convert the format first?
Yes. Choose JPG, PNG or WebP as the output and the image is re-encoded before being encoded as Base64.
