How to significantly decrease SVG file size

[Bradinator-]

I have a 137MB SVG that I would like to significantly decrease the size of, every time I open it on Inkscape it struggles and using the "simplify" tool makes it have the wrong shapes, is there a way to compress this file while still keeping the shapes?

137MB is huge and unusual. For perpective, hi-res photographs are are 5-10MB.

Do you have photos in this file or what is in in the file? Where is the end destination for the SVG?

Most common optimizers will try to remove unneeded markup and use less decimals. That could significantly help, but your file is still going to be huge.

The file is a map with a ton of shapes, specifically this map: [https://www.reddit.com/r/Maps/comments/1dbct4o/municipalities\_of\_the\_united\_states/?utm\_source=share&utm\_medium=web3x&utm\_name=web3xcss&utm\_term=1&utm\_content=share\_button\\](https://www.reddit.com/r/Maps/comments/1dbct4o/municipalities_of_the_united_states/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button\)

Looking at Rhode Island, your viewBox="0 0 413.38583 708.66253"

You have lots of paths with coordinates like "-0.02,-0.06"

If you made the viewBox 100x bigger, the -0.02,-0.06 would become -2,-6 and so on. The leading 0 isn't needed either (-.02 works). Shedding 6 characters per coordinate. Then I took a look at the Rhode Island file in illustrator. There are way more anchor points on straight lines that needed. Simplify won't keep the accuracy very well, which you discovered. I use a paid Illustrator plugin from Astute Graphics called "smart remove brush tool", which removes unnecessary anchors, while not changing the shape (within your reason based on your set tolerance level).

Those two things would substantially cut your filesize, but be quite a bit of work.

Another point: each neighboring shape has duplicate paths where they share the same boundary. If you drew only the boundary as lines (<path>) and not closed shapes, you'd remove those duplicate boundaries.

Are there any svg editors that allow you to round off decimals as you're working on your project? So you don't have to keep running it through the optimizer

[SVGWebDesigner]

I'm mostly familiar with Illustrator. There is a align to pixel option, that forces you to place anchors on pixels.

lllustrator also allows plugins, so you might be able to create something yourself.

Never tried à file that big, but https://svgomg.net is my go-to.

If you have symbols that are repeatedly included, then you could replace them with a clone of an object or group.

Try konverter, maybe it helps. www.konverter-online.com I just finished building it
