Removing this will have no impact on the image, but will cause the layer name to be lost if you were to open the file up in illustrator. These are coordinates for the top left position of the image, safe to remove from an individual SVG. This attribute is supposed to make the background available to child elements. These attributes control the dimensions of the image much the same as how a standard image is scaled in HTML. Groups are a container for paths and shapes. Useful for organising paths in the creation of the SVG, but unless you plan on using CSS to animate or move the group and its children around inside the SVG element, the group tag can be removed without any ill effect.
Depending on your own use of SVGs, the amount of unnecessary code can quickly accumulate and may lead to a poor user experience. There are tools that exist to make the job easier. I suggest you take a look at the tools below to help :. Raygun Real User Monitoring. This has been great news for web developers concerned about SVG performance, but there is still some way to go, particularly with very large and detailed SVG files such as complex diagrams and maps, especially considering the trend towards browsing the web on mobile devices.
Here are 6 tips for optimising SVG files:. Moving styles into CSS is a lossless optimisation that both reduces file size making the file faster to load , as well as improves render speed by allowing the web browser to better optimise drawing.
Using groups to apply styles rather than applying styles to each path is a lossless optimisation that reduces file size making the file faster to load , as well as improves render speed by allowing the web browser to better optimise drawing.
Using relative positions rather than absolute positions is a great, lossless way to reduce file size making the file faster to load. This can sacrifice readability for humans, but it can significantly reduce file size, especially when small adjustments are made to shapes with large X or Y positions.
This is one of the smaller optimisations, but nonetheless a worthwhile one. It is a lossless way to reduce file size, making the file faster to load. Excessive accuracy is often seen in SVG files that are automatically generated. From this time stems the good support of SVG in Illustrator. However, the resulting SVG often shows some quirks, that make it necessary to post-process it for general applicability.

Several projects exist that can create a raster image from an SVG source. ImageMagick is one of the most famous command-line image processing tools.
