Once converted to Base64, encoded image data will look similar to this (shortened for simplicity):,Other file types like XML and JSON also supports Base64 encoded images. Start by uploading an image file above and play with the different possibilities.,The string can be used instead of an URL in the src attribute of the img element in HTML:,Base64 images are primarily used to embed image data within other formats like HTML, CSS, or JSON. By including image data within an HTML document, the browser doesn't need to make an additional web request to fetch the file, since the image is already embedded in the HTML document. A Base64 representation of an image is larger than a separate image and the string gets very long for large images. You should primarily use Base64 for small images and always test both embedded and external images to see what works best.

Well, you can notice it clearly that the process of showing normal images from a directory on the web page is same as here we show the image from base64 binary coded text. Here you just have to put “data:image/png;base64, BASE64_CODE_FOR_THE_IMAGE” inside for the src.,To retrieve an image from a base64 text, you need to follow rules of HTML. It is very easy to show the image from base64 encoded text in HTML.,The image type here is PNG. If you want to test it with any other image then you need to get the base64 encoded code of your image which you can get from any online image to base64 converter.,Below is the HTML code that will show the image for the base64 code on the web page:

The HTML code syntax to show an image from base64 binary code will be like below:

How do I make the images in base64 correctly displayed in the emails using sendgrid as a mailing client?,Right. I see that. deprecation is brutal. But I also use another massive Mail client (mandrill) where I embed images and it works perfectly well. The thing is, sendgrid works a lot better and since I always use base64 images for emailing, I want to keep doing that way because it's simple.,It might be because base64 encoded images are not supported by all email clients.,Anyone has any idea of another way to embed images in HTML and being properly processed by sendgrid?

<!DOCTYPE html>
<html lang="en" dir="ltr">

<head>
   <meta charset="utf-8">
   <title></title>
</head>

<body>
   <img src="data:image/png;base64, // all the encoded base 64 that follows" alt="">
</body>
