About the Image to Base64 Converter

This tool converts images into Base64 encoded strings, which can be embedded directly into HTML, CSS, or JavaScript code. This is useful for creating self-contained web pages, reducing HTTP requests, or storing images in databases.

The conversion happens entirely in your browser, so your images are never uploaded to a server. The Base64 string can be copied as plain text or as a complete data URI ready to use in your code.

Common use cases

  • Embedding small images in HTML emails
  • Using images in CSS without separate files
  • Storing images in localStorage or databases
  • Creating offline-capable web applications
