Once the problem has been identified the first thing to do is create a mechanism to pull the base64 encoded images out of a block of content and create file entities.

The developers then saved this content directly into the database, which then created a problem as the Drupal API then became slow to respond. I have also seen this happen in a couple of decoupled Drupal sites where users were given a CKEditor box to edit content and this sends base64 encoded images back to the Drupal site. When the post is saved the data is saved to the database along with the encoded image. Instead of creating the file reference, CKEditor will instead embed the file directly into the content area. The main culprit of this base64 image encoding problem is when a user drags an image into the body field of a Drupal post. The image element would look something like this. In certain situations it is possible to embed images directly into content. You might see an image element that looks like this. Let's say that when you embed an image into some copy on a Drupal site using the normal media or file embed features. It can also put unnecessary strain on the database due to the increased time taken to return data. Whilst it is technically possible, it creates more problems than it solves and even sites with a couple of thousand nodes can have databases of many gigabytes in size due to this issue. If you can't tell, I really dislike this method of image storage. It isn't possible for the browser to make that decision any more and that can lead to more slowdown for the user.

By injecting files into the content you are forcing your users to download very large pages every time they want to request a page. When you download a file from the web your browser can make a decision on whether to fetch that file a second time. Instead of fetching a few kilobytes of data from the table the database is forced to fetch many megabytes of data, which can create a bottleneck for other requests. Whilst this is technically possible, it massively balloons the size of the database and can often slow down page load times due to the database being slow to respond to the request. The original binary data can then be re-created using this string and the data is understood by lots of different technologies (including web browsers). This is the approach of taking the binary data contained in a file and converting it into a string of characters.

So browser has to do roundtrip to get full content.Occasionally, I have come across Drupal sites that have base64 encoded images embedded into content fields. If you apply base64 encoding to lots of medium sized images it will increase HTML content size or CSS content size.IE6 & IE7 not supports Data URI which means base64 images will not be loaded in ie6 & ie7 browsers.Even if we apply gzip compression, doing so will only decrease css file size to around 10-12%.So more data has to be transferred on internet. than what it is actually in its binary form.

Doing so will increase image size approximately 20-25%.

Though Base64 increases performance but be careful.

Image encoded data can be saved inside database and can generate image file.

Removes separate HTTP Requests for image loading by wrapping encoded image code inside css or HTML.

Because most of page load time is taken for transferring data over internet.

That will definitely increase performance of website. Doing this will reduce the number of HTTP requests because client (browser) donвЂ™t have to issue separate request for images. If we encode all our websites small images, wrap them inside css or html code.
