Can a Base64 image be displayed in HTML?

Base64 encoding and Data URL go hand-in-hand, as Data URLs reduce the number of HTTP requests that are needed for the browser to display an HTML document. In this snippet, we’ll demonstrate how you can display Base64 images in HTML.

What can I use Base64 image maker for?

You can use the Base64 Image maker for not so important images that do not bring traffic, for example, social icons. Little icons such as Twitter, Google+, Facebook, etc. images are really small and have no need to be indexed.

What is the history of the base64 algorithm?

(Wikipedia) Initially, the algorithm was named “printable encoding” and only in June 1992, RFC 1341 defines it as “Base64”. The 64 characters represent the 64 place-values for the base varies between implementations. The history of the Base64 algorithm started when, in the past, engineers argued over how many bits should be in a byte.

Why are there 64 characters in the Base64?

The 64 characters represent the 64 place-values for the base varies between implementations. The history of the Base64 algorithm started when, in the past, engineers argued over how many bits should be in a byte. Some decades ago, seven-bit, six-bit, and three-bit bytes were used.

How to use Base64 encrypted code in PHP?

Here is a corrected version: A function I’m using to return local images as base64 encrypted code, i.e. embedding the image source into the html request. This will greatly reduce your page load time as the browser will only need to send one server request for the entire page, rather than multiple requests for the HTML and the images.

How big is a Base64 encoded png image?

If you don’t like having small 1×1 pixel images in your projects, you can embed the base64 encoded pixel directly in your css or html source files. We always try to generate the smallest possible PNG image. Our 1×1 transparent pixel for example uses only 68 bytes.

Why is it necessary to return 0 in base64 PHP?

This is necessary because file_get_contents can return 0 and be casted to false in some cases, even if the file fetch was successful. Actually in this case it shouldn’t happen, but its a good practice when fetching file content. I’m not sure, but check this example http://www.php.net/manual/es/function.base64-encode.php#99842
