About this tool
Convert any image to a Base64 data URI with ready-to-paste HTML img and CSS background-image snippets. Inlining tiny images (icons, tracking pixels) removes HTTP requests from your critical path.
How to use the Image to Base64 Converter
- Drop an image (keep it small — under ~5 KB ideally).
- Copy the data URI, HTML tag or CSS rule.
- Paste directly into your code.
Frequently asked questions
When is Base64 embedding a good idea?
Only for tiny, frequently-used assets — the encode adds ~33% size and skips caching, so large images get slower, not faster.
Is the image uploaded?
No — encoding happens in your browser via FileReader.
