Image to Base64 (Data URL Generator)

How to Use


Drag an image into the drop zone (or click to choose). The file is encoded into a Base64 string and a data URL. The data URL is ready to drop into a CSS `background-image` or an HTML `<img>` `src`; the raw Base64 string is also available separately if you need just the encoding.

Base64 and Data URLs


Base64 encodes arbitrary binary data as ASCII text. A data URL (`data:image/png;base64,...`) wraps Base64 with the MIME type so it can be embedded directly in HTML or CSS. Base64 inflates byte size by about 33%, so embedding large images bloats the surrounding HTML/CSS — keep this for icons and small assets.

Use Cases


  • Inlining small icons directly into CSS or HTML
  • Embedding images in email templates without external hosting
  • Building self-contained single-file HTML demos
  • Including icons in a browser extension manifest
  • Generating sample data when an API expects a base64 string

Privacy


Reading and encoding happen entirely in the browser via FileReader; the image never leaves your device. Internal or confidential images stay local.
