Convert an image into a Base64 data URI you can paste directly into HTML or CSS — no separate file, no extra HTTP request.
Embedding a small image as a Base64 data URI inlines it straight into your HTML or CSS, removing a network request and keeping tiny assets like icons and logos self-contained. This tool encodes your image and gives you the full data URI ready to copy.
Base64 is best for small images — large files become bulky strings, so use it for icons, sprites and small backgrounds.

Frequently asked questions
When should I use Base64 images?
For small assets like icons and logos. Large images create huge strings and are better served as normal files.

Is the encoding lossless?
Yes — Base64 encodes the exact bytes of your file with no quality change.
