A Guide on Optimizing SVGs for the Web

Scalable Vector Graphics (SVG) is a two-dimensional vector code built on XML. Simple objects, pathways, and everything else you can accomplish in Illustrator may be used as vectors. It’s a picture type that looks more like a website page than a JPEG. Because we can optimize SVGs for the web with coding (whether in our word editors or with CSS/JS), it is far more effective than alternative file types we may utilize on the internet.

Algebraic formulas represent the SVG graphic under the hood, which means it can scale indefinitely. Scaling requires mathematical processes like multiplications since it employs integers rather than pixels.

SVG files are quality adaptive, which is one of their main advantages. It implies that SVG files maintain their quality regardless of display resolution or dimensions, unlike JPG or PNG files.

So that there is no deformation, websites rewrite the mathematics behind the picture. As a result, an SVG maintains its clarity on a retina screen in which a PNG may seem blurred if it isn’t sufficiently large.

Optimizing an SVG

Optimizing SVGs for the web and for online usage is a basic procedure that is no extra difficult than downloading a JPEG or PNG image. Operate with the image at the scale you want in your chosen vector images editor(Illustrator, Sketch, Inkscape, and perhaps Photoshop if one utilizes shape elements).

If you don’t intend to design them with a website font they’re applying on the site; you’ll need to transform any content to outlines because it won’t appear in the correct font. Don’t bother with turning all of your objects into concrete shapes, mainly if you include strokes. You’ll probably need to modify them on the site anyway, and enlarging them won’t make the document any smaller. 

Any titles you give to layers/groups would be included as an ID in the SVG for that component. This is useful for designing, but it will increase the final capacity of the document. To save, make sure the layout is located in an entire pixel region (not 23.3px86.8px) or else it won’t be sharp, and afterward, trim the artboard around it. 

Object > Artboards > Fit to Artwork Bounds in Illustrator can be used to accomplish this. After that, press saves as and select SVG with the default parameters. You may tweak these parameters if you like, but it’s not worthwhile because we’ll be post-processing them anyhow, so any effort you invest in toying with these is useless. The above is how you can go about optimizing SVGs for the web.

Editing the SVG

If users understand how optimizing SVGs for the web goes about, they should be able to get the smoothest, leanest outcome possible. If you’re curious to discover more about SVG pathways, look up the MDN docs and this webinar by Heydon Pickering.

However, for the large majority of people, modifying an SVG is usually possible with a visual program. Although Adobe Illustrator is widely used, alternate editors, such as Sketch, offer equivalent editing features.

The amount of coding one may remove by altering an SVG is determined by its structure and purpose. The following pointers apply to symbols and simple images in general. Detailed illustrations can’t permanently be changed to the same extent without impacting the finished product – and might be best served like PNGs and JPGs in certain circumstances.

Exporting the SVG

When saving from Illustrator, go to File > Save As and choose SVG as the type. On the following page, we’ll see some SVG choices. For stylistic alternatives, we should look into “Presentation attributes.”

After completing these stages, the SVG is run via an optimization program. After running these custom optimizations, one could get by choosing most of the settings in SVGOMG for icons. You’ll realize how much clearer and more straightforward the software is! Even yet, this may not necessarily eliminate everything that can be removed. A last mechanical clean-up in the code editor is recommended. The SVG is finally available for use!


This may be a long list of procedures, but if you’re familiar with your graphics program, you’ll find that the entire process requires remarkably little effort. It becomes muscle memory within a couple of times. The majority of the SVG icons are optimized in a bunch at the start of a venture to facilitate utilizing them in context much simpler. It’s worthwhile spending a little time now to make your visuals simpler to deal with afterward.
