About Data URI Generator
The Data URI Generator turns a dropped image into a complete data: URI plus copy-ready HTML and CSS snippets. It is for developers who want the URI and the markup to use it in one place.
A data URI is more useful with the surrounding markup ready to paste. Generating both locally saves steps and keeps the image private.
Step by step
- Drop an image into the tool — Data URI.
- The complete data URI is generated.
- Copy-ready HTML and CSS snippets are produced alongside.
- Choose the snippet you need.
- Copy it into your project — Data URI.
What it offers
- Complete data URI output
- Ready HTML and CSS snippets
- Image encoded locally
- Copy-ready results
Where it helps
- Inlining a small image with the markup ready to go
- Getting both the URI and a CSS background snippet
- Embedding an icon directly in HTML
- Producing a self-contained image reference
Tips for best results
- Inline only small images; reference larger ones as files.
- Add alt text when you use the HTML snippet.
- Prefer cached files for images shared across many pages.
Pitfalls to watch for
- Inlining large images, which bloats your HTML or CSS.
- Using a data URI where a cached file would perform better.
- Forgetting alt text when pasting the HTML snippet.
