How to use the Image to Base64

  1. 1
    Upload an image

    Choose the icon or small graphic to inline.

    Encode to Base64

    We generate the full data URI string.

    Paste the data URI into your HTML or CSS.

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.

  • Full data URI, ready to paste
  • Removes an extra HTTP request
  • Great for icons and small assets
  • Works in HTML and CSS

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.

Does it work in CSS?

Yes — paste the data URI as a background-image value or in an <img> src.

Is the encoding lossless?

Yes — Base64 encodes the exact bytes of your file with no quality change.
