Embed Image In Html Base64 – How much faster is using inline/base64 images for a web page than linking to a hard file?

How much faster is using base64/line to display images than connecting to a hard file on the server?

Let’s define “speed”: the time it takes for a user to view a rendered HTML web page

Base64 encoding will expand the image by a third, increasing bandwidth usage. On the other hand, including in a file removes another GET round trip to the server. Therefore, a pipe with good bandwidth but poor latency (like a satellite Internet connection, for example) will load a page with embedded images faster than if you were using separate image files. Even on my (rural, slow) DSL line, sites that require a lot of round trips take longer to load than sites that are relatively large but only require a few GETs.

If you perform base64 encoding from the source files with every request, you will use more CPU and destroy the data cache, which will hurt your server’s response time. (Of course you can always use memcached or similar to solve that problem).

This prevents most forms of caching that can do a lot of harm if the image is rarely viewed – say, a logo that is displayed on every page, usually a logo that the browser can cache (or a proxy cache like Squid or whatever) and request once a month. This will prevent optimizations for web servers from serving static files using kernel APIs such as sendfile(2).

Basically, this will help in some situations and hurt others. You need to identify which situations are important to you before you can figure out if this is a worthwhile trick for you.

When the same image is loaded multiple times, if it is declared inline, the browser makes one request for each image (I think base64 decodes each image), but otherwise, the image is requested once. For each document (see comparison image below).

A document with embedded images loads in about 250ms, while a document with linked images takes about 30ms.

The situation in an HTML document with multiple occurrences of the same inline image does not make sense a priori. However, I found that the jquery lazyload plugin defines an inline placeholder by default for all “lazy” images.

Attribute will be set to it. Then, if the document contains a lot of lazy images, a situation like the one described above can occur.

Another (and perhaps more important) point is that if there are many images, the browser cannot receive them simultaneously (ie in parallel), but only a few at a time — so the protocol ends up being chatty. If there is an end-to-end delay, multiplying by the end-to-end delay for each image divided by the number of images at once gives a significant amount of time before the last image is loaded.

With base-64, each 8-bit character represents 6-bits: so binary data is decomposed in a ratio of 8 to 6, which is only about 35%.

In fact, if you do this in a CSS file, it will still be cached. Of course, any CSS changes will be invalidated by the cache.

In some cases this can be used as a huge performance boost on many HTTP connections. I say some situations because you can use techniques like Image Sprites for most things, but it’s always good to have another tool in your arsenal!

What is Base64 encoding Base64 is an encoding algorithm that allows you to convert any character into the alphabet, including Latin letters, numbers, pluses, and slashes. You can convert images into a “readable” string that can be saved or transferred anywhere.

Significance Of Embedding Images In Html

We can’t just send a Base64 string to our server and process it, how is it different from any other string? How do you know if a file is an image or a PDF file? That’s where the data URI comes in.

Data URI or Data URL is a format in which we can use some data as an inline string. In order to process our Base64 data on the server, we need to know what mime type (and whether it can be spoofed) the URI format of the data it returns.

To upload files as Base64, we need to listen for our file input’s change event, the process is asynchronous, so we need to catch some states to determine if we can submit the form or not.
