About Image to Base64

The Image to Base64 converter encodes any image file into a Base64 data URI — a text string that represents the complete image binary data. Data URIs can be embedded directly in HTML `<img>` tags, CSS `background-image` properties, or JSON API payloads, eliminating the need for a separate file HTTP request. This is commonly used in HTML email templates (where external image links may be blocked), single-file applications, offline-first web apps, and when passing images through APIs that only accept text.
