Frequently Asked Questions

What is a Base64 data URI used for?

Embedding an image directly inside HTML, CSS, or JSON without needing a separate image file — common for small icons, email templates, or single-file web components.

Why is the Base64 text so much longer than my file size?

Base64 encoding increases size by roughly 33% compared to the original binary file — this is a normal, expected part of how the encoding works.

Should I use this for large images?

Generally no — Base64-encoded large images bloat your HTML/CSS file size and lose the caching benefits of a separate image file; it's best suited for small icons and images.

What formats are provided?

A raw data URI, a ready-to-paste HTML tag, and a CSS background-image snippet — pick whichever fits where you're using it.
