I've a problem with a complicated SVG image.
It works on Chrome and Firefox, but there is no way to convert it into a PNG image even using an online tool or GIMP and also with Inkscape.
I'm not sure where the problem is. Maybe because is it an image built with two other SVG images embedded.
Here is the SVG file.
To reproduce the problem: open the SVG file linked with a browser: it works.
Open it with GIMP and the image is empty.
An easier example with the same problem:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg">
<!-- Some graphical objects to use -->
<defs>
<svg id="pippo" viewBox="0 0 10 10" >
<circle id="myCircle" cx="5" cy="5" r="5" />
</svg>
<linearGradient id="myGradient" gradientTransform="rotate(90)">
<stop offset="20%" stop-color="gold" />
<stop offset="90%" stop-color="red" />
</linearGradient>
</defs>
<!-- Using my graphical objects -->
<rect height="100%" width="100%" fill="#fc0" />
<use x="0" y="0" href="#pippo" fill="url('#myGradient')" />
</svg>
With SVG 1 you need to use the attribute xlink:href instead of href on the use element
<use x="0" y="0" xlink:href="#pippo" fill="url('#myGradient')" />
You will also need the xlink namespace on the <svg> element
<svg
viewBox="0 0 10 10"
xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
>
Since SVG 2, xlink: prefix is deprecated but SVG 2 is a W3C Candidate Recommendation and all its features are not yet supported by all browsers and editors.
Full SVG 1 example:
<?xml version="1.0" standalone="no"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg viewBox="0 0 10 10" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
<!-- Some graphical objects to use -->
<defs>
<svg id="pippo" viewBox="0 0 10 10">
<circle id="myCircle" cx="5" cy="5" r="5" />
</svg>
<linearGradient id="myGradient" gradientTransform="rotate(90)">
<stop offset="20%" stop-color="gold" />
<stop offset="90%" stop-color="red" />
</linearGradient>
</defs>
<!-- using my graphical objects -->
<rect height="100%" width="100%" fill="#fc0" />
<use x="0" y="0" xlink:href="#pippo" fill="url('#myGradient')" />
</svg>
Workaround: SVG to PDF via the native browser feature "save to PDF" (print modal)
Since Firefox, Chromium, and WebKit have powerful built-in PDF export functionalities combined with way better SVG support than any "desktop" application, we can convert complex SVG images to a flattened, 'visually hardwired' vector file.
Ideal result
all vector data is retained (can also be opened in a vector application like Inkscape, Adobe Illustrator, Figma, etc.)
complexities like nested SVG images or <use> elements as well as transforms are repositioned to hardcoded vector x/y coordinates.
... but curb your enthusiasm: common issues
patterns and some complex gradients might be rasterized
you will lose structural data like layers, IDs and other editable features.
Manual SVG export optimisations
as #Yukulélé already pointed out: some syntax conventions and newer attributes might be too progressive
try to replace CSS-based styling with attributes – svgomg can be helpful
reusable elements defined in <defs> or as <symbols> might have quirky recursive dependencies
try to clean up unnecessary or invalid properties (e.g., hexadecimal RGBA) and fix incomplete SVG nestings (missing end tags)
document dimensions and aspect ratios can often be better retained (by a graphic application),
when the parent SVG element was added a viewBox and width/height attributes (at least in Adobe Illustrator)
I'm trying to hack together a sprite sheet from a set of icons. I know almost nothing about SVG. I can get the simple icons to work, but an icon with a clip path isn't displaying properly. From what I can tell it seems like it's not using the clip path.
The sprite works in jsfilddle and it works if I just load the svg on it's own and include a < use > statement in the SVG. But if I have a separate < use > it doesn't work.
All my testing has been done in Chrome (50.0.2661.94)
<svg xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg" version="1.1">
<defs>
<clipPath id="folder-clip-0">
<path d="..." />
</clipPath>
<symbol id="folder" viewBox="0 0 32 32">
<g class="container" data-width="32" data-height="27" transform="translate(0 2)">
<path d="..." class="..." />
<path class="..." d="..." />
<path clip-path="url(#folder-clip-0)" d="..." class="..." />
</g>
</symbol>
</defs>
</svg>
I'm using it like so:
<svg>
<use
xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="/img/path/sprite.svg#folder">
</use>
</svg>
When I use the separate statement it looks like this:
But it should look like this:
The color difference is not relevant, it's just the background when the image was taken.
Edit:
I just discovered that if I dump the whole sprite sheet into the page HTML and reference it locally instead of an external file it works. So I don't know what's wrong with my external reference.
e.g.
<svg>
<use xlinkHref={"/img/path/not/work/sprite.svg#folder"}></use>
</svg>
vs.
<svg>
<symbol id="folder"></symbol>
</svg>
<svg>
<use xlinkHref={"#folder"}></use>
</svg>
This works for me as a fallback, but I'd rather have an external SVG file instead of embedding it in my HTML.
Edit 2:
If the SVG sprite sheet is embeded in the HTML directly using the external link shows the icon correctly.
This seems to be a browser support issue. Using the external reference works as expected in Firefox. Chrome doesn't handle clip paths and some other functions in external references. There's an outstanding bug report filed. Safari also doesn't support it.

I downloaded some 16x16 SVG icons that used the viewbox attribute to scale the original code to fit into 16x16 canvas on download. Now what I am experiencing is that I can not insert the SVG from an external file anywhere as the viewbox attribute just isn't working on it. If I place the SVG code inline then it works.
Am I missing something, or is this just how it is?
Here is the code.

Note that it's viewBox not viewbox - the browser might save you sometimes, but not always.

I'm writing a web application which generates SVG images in the browser.
The SVG's I'm generating work fine in ever browser. However, when I download one of the SVG's and try to open it in Adobe Illsutrator, all the transformations are all over the place.
They are in fact so different that you have to zoom right out to see where the shapes are positioned.
This is the contents of the SVG, you can see it's pretty simple. Just a couple of nested SVG's and a few basic shapes:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="592" height="592" xmlns:xlink="http://www.w3.org/1999/xlink">
<svg style="overflow:visible;" x="88.80000305175781" y="88.80000305175781" fill="#777777">
<svg style="overflow:visible;" height="100px" width="100px">
<rect width="100" height="100" style="stroke:#006600;" transform="scale(4.144 4.144)"></rect>
</svg>
</svg>
<svg style="overflow:visible;" width="592" height="592" x="176.60000000000016" y="177.60000000000014" fill="#000000">
<rect width="592" height="592" fill="rgba(0,0,0,0)" stroke="#bbbbbb" transform="scale(0.4 0.4)"></rect>
<svg style="overflow:visible;" x="-0.0000015258789005656581" y="-0.0000015258789005656581">
<svg style="overflow:visible;" height="48px" width="48px">
<ellipse id="SvgjsEllipse1010" rx="24" ry="24" cx="24" cy="24" style="stroke:#006600;fill:#00cc00;" transform="scale(4.933333333333334 4.933333333333334)"></ellipse>
</svg>
</svg>
</svg>
</svg>
I don't know the SVG spec inside out, but I'm doing anything particularly complex, so it all seems good to me. I can't see a reason why Illustrator would render it so differently to browsers.
Does anyone know why this is happening?
Edit
This is what it looks like in Illsutrator, as you can see the scaling and positioning is all off, the small square in the center is the 592 x 592 canvas area, so you can see who far I am zoomed out.
I suspect AI doesn't like/handle/expect nested <svg> elements. Try replacing them with groups. Those with x and y attributes may need to have a transform added to get it to look the same. Also if the overflow is important, you may need to tweak things further as that property is not valid for group elements.
