: I made a map in AI, but the file size is HUGE as an svg? I made an svg in Illustrator, but now I want to use it in a website/app but it's a huge size (around 10 MB) how can I decrease

@Barnes313

I've ran into this several times with Illustrator CC-2014 and I will use the below as an example:

Just a few shapes, colors, and guides.



File -> Save As select SVG (svg)



After selecting SVG an option box will appear so select SVG Code...:



The code will either output in your default code editor or open a .txt file:

<?xml version="1.0" encoding="utf-8"?>

If you notice from the above code I have three layers and they are Layer_1, Layer_2 and Layer_3. In this instance it didn't output the guides but sometimes I have seen it as id="guide" if I recall.

I would trim the code down to this:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
viewBox="0 0 713 956" enable-background="new 0 0 713 956" xml:space="preserve">
<g id="Layer_1">
<path fill="#F1F2F2" stroke="#000000" stroke-miterlimit="10" d="M472.5,359.6c-82,0-148.5-66.5-148.5-148.5
c0-16.7,2.8-32.8,7.9-47.9c-9.4-1.1-18.9-1.6-28.5-1.6c-138.9,0-251.5,112.6-251.5,251.5s112.6,251.5,251.5,251.5
s251.5-112.6,251.5-251.5c0-25.1-3.7-49.3-10.5-72.2C523.1,352.9,498.6,359.6,472.5,359.6z"/>
</g>
<g id="Layer_2">
<circle fill="#E6E7E8" stroke="#000000" stroke-miterlimit="10" cx="488.3" cy="638.9" r="148.5"/>
</g>
</svg>


and the above SVG can be called as an image in your files.

That is one way to do it but I've learned and have been testing another. In my XHTML files I trim it down all the way to the SVG itself like so:

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<path fill="#F1F2F2" stroke="#000000" stroke-miterlimit="10" d="M472.5,359.6c-82,0-148.5-66.5-148.5-148.5
c0-16.7,2.8-32.8,7.9-47.9c-9.4-1.1-18.9-1.6-28.5-1.6c-138.9,0-251.5,112.6-251.5,251.5s112.6,251.5,251.5,251.5
s251.5-112.6,251.5-251.5c0-25.1-3.7-49.3-10.5-72.2C523.1,352.9,498.6,359.6,472.5,359.6z"/>
<circle fill="#E6E7E8" stroke="#000000" stroke-miterlimit="10" cx="488.3" cy="638.9" r="148.5"/>
</svg>


BUT be aware after some testing I have found that the <svg> tag should be enclosed inside a <div>. Doing it this way saves down on the code and I can easily animate it this way.

Yes, you should delete any extra elements before saving out your svg. Also how complex is your map? Svg's typically perform best without gradients, clipping masks, or additional effects like drop shadows. If you need to keep the detail why not just do a save for web from Illustrator as a png?
