About the Image to Base64
A Base64 data URI embeds an image directly inside CSS, HTML or JSON, removing an extra network request — a classic trick for small icons, email templates and single-file demos. Drop an image here and this tool produces the full data URI plus ready-made snippets: a CSS background-image rule, an HTML img tag and a JSON-safe string. It also warns when the file is too large for embedding to be sensible.
