사용 방법
A data URI embeds an image directly into your code as text, so it loads without a separate file request — handy for small icons and self-contained HTML. This encodes it in your browser.
- 1You drop in an imageIt's read locally with the FileReader API — never uploaded.
- 2It's Base64-encodedThe image bytes become a data: URI (data:image/...;base64,…) right in your browser.
- 3You pick a snippetCopy the raw data URI, or ready-made CSS (background-image), HTML (<img>), or Markdown.
- 4Paste it into your codeThe image now travels inline with your CSS/HTML — no extra file to host.
The image is encoded entirely on your device. Note that Base64 is ~33% larger than the original, so data URIs are best for small images.
