Questions
Is my image uploaded anywhere?
No. The image is encoded in your browser, so it stays on your device.
What is a Base64 image used for?
It lets you embed a small image directly in HTML, CSS, JSON or email, with no separate file to load.
Why is the Base64 text bigger than the image?
Base64 makes data about 33% larger. It works best for small images like icons and logos.
What is the difference between the output formats?
Data URI is the full string that starts with data:image. Base64 only is the raw encoded part. HTML and CSS wrap the data URI so you can paste it straight into code.
