You can manually embed fonts into your SVG to resolve this, but most times, will result in large SVG size, and therefore negating the advantages SVG has, over other image formats. This is mainly because images with tags are not allowed to refer to external resources including CSS, fonts and scripts, for security reasons. If you use an tag with web fonts, the fonts will fail to render and resort to using only system fonts. Streamlined, as with other image formats. The tag is now supported across all major browsers that support SVG (IE9+). It has a syntax that is similar to how we embed other image formats like PNG, JPEG and GIF: The best and the simplest way to embed SVG into HTML is to use the tag. Ideally our SVG should be easy to maintain, just create and embed without the need to ensure their classes and IDs do not clash, otherwise with a growing number of images on our websites, this is gonna create display problems which is difficult to detect. The embedding method we choose should result in an easy and streamlined workflow, that do not require extra work with maintaining complicated CSS and embedding methods. Therefore, it makes sense for better SEO (Search Engine Optimization), that the embedding method we adopt would allow search engines to list our images on image search.

Google has publicly stated that it will index and crawl SVG files. Especially when we have multiple images, ideally our embedding method should be able to refer to a single CSS, font or javascript file (to save resources) and be able to manipulate our embedded SVG. Interactivityīecause of security reasons, some SVG embedding methods will block access to external resources including CSS, fonts and javascript. According to the World Wide Web Consortium, SVG offers anything between 75% - 85% compression ratio, reducing a 16KB file to only 4KB, resulting in considerable bandwidth and speed savings. Unlike PNG and JPEG formats (practically, already compressed), SVG images are very well suited for compression. Ideally the embedding method will allow easy browser caching and cache busting. It pays to enable browser caching for all static assets including SVG images. We all know page speed will be a ranking factor on search engines, especially on mobile sites. Ideally, whatever way you choose to embed an SVG, you should have alt and title attributes. A title attribute allows hovering over the image to obtain more information. An alt attribute allows a user to view the image description, even when it fails to render on a device, in addition to providing context for search engines. When we embed an image onto HTML, it's always good to have alt and title attributes, for better accessibility. If you are embedding an SVG onto your website in this day and age, chances are, you have a lot more factors to consider, in addition to browser compatibility.īefore we do a comparison, let's have a look at what factors we are considering, when making a decision: Design considerations Alt and title attribute availability If possible use static compression, and compress your SVG with Brotli for the smallest sizes. : Updated inlining with ability to index text and select them.: Updated for 2019, img tag is still the best way, after compression with Nano.

: Update to include maintenance considerations for all embedding formats.

: Updated to include static compression with Brotli for even smaller file sizes.

You've probably came across various ways to embed SVG in HTML, but with the latest browser and technology updates, do we still need an tag or can we use instead? What are their pros and cons and how do they compare?
