Key features

  • Encodes any image into a complete data:image/...;base64 string instantly via FileReader.
  • Copy as the raw data URL or as a ready-to-paste CSS background-image rule.
  • Stat tiles show the original size, Base64 character count and the encoding overhead.
  • A 'rendered proof' image whose source is the generated string confirms the encoding is valid.
  • Everything happens locally — no network request is involved at any point.

How it works

  1. Drop A Small Asset

    Icons and logos under roughly 200 KB are the ideal use case.

  2. Read The Stats

    The tiles show how much weight the encoding adds compared to the original file.

  3. Copy What You Need

    Grab the plain data URL or the formatted CSS rule with one click.

  4. Paste Into Your Code

    Use it in an img src, a CSS background, or a single-file HTML document.

Tips for better results

  • Base64 inflates files by about a third — the overhead tile shows the exact figure, so embed only small assets.
  • Data URLs eliminate one network request and keep working offline inside a single HTML file.
  • For large hero images, stick to normal files; embedding them bloats your HTML or CSS.
