Removing transforms in SVG files
SvgTransformInkscapeSvg Problem Overview
I have been struggling with this for a while, and can't seem to find an answer (that works) anywhere. I have an SVG file which looks like this:
<svg
xmlns:dc="http://purl.org/dc/elements/1.1/"
...
width="72.9375"
height="58.21875"
...>
...
<g
...
transform="translate(10.75,-308.96875)"
style="...">
<path
inkscape:connector-curvature="0"
d="m -10.254587,345.43597 c 0,-1.41732 0.17692,-2.85384 0.5312502,-3.5625 0.70866,-1.41733 2.14518,-2.82259 3.5625,-3.53125 1.41733,-0.70866 2.11392,-0.70867 3.53125,0 1.41732,0.70866 ... z"
... />
</g>
</svg>
I want to remove the transform="..."
line but still have my image stay where I've placed it (in InkScape). If I manually remove the transform, the image zips to another part of the screen (as expected), but I need to get rid of the transform altogether and, at the same time, have the image stay exactly where I want it. Is there a way to remove/flatten the transforms into the path coordinates themselves? (The only transforms I have to deal with are translate and scale, no matrices.)

How to remove transforms in Inkscape
- Open svg file in Inkscape
- Go to Edit -> Select All
- Go to Object -> Ungroup
- Go to Edit -> XML Editor
- Find "transform" attributes in layers and delete them
How to move all objects altogether without creating another transform attributes
- Go to Edit -> Select All in All Layers
- Go to Object -> Transform
In Transform panel
- Uncheck Relative move and check Apply to each object separately
- Set Horizontal and Vertical values according to your needs and click Apply

There is inkscape extension called Apply Transforms that recomputes paths with their transforms. This is exactly what I've been looking for.
After installing it you'll find it menu under Extensions > Modify Path > Apply Transform.

I worked out what the problem was. I was hoping not to have to resort to Robert's answer, although I am glad for confirmation that it would work! In the end Duopixel's answer was actually the closest, although it turns out something else was going on as well.
When you're working with different paths in Inkscape documents, I believe its default behaviour is to group them together under an <svg:g.../>
tag. When modifying paths in a group, Inkscape will automatically add a transform to the group to represent these changes. However, if you open the XML editor and drag your path outside the <svg:g.../>
tag and make it its own <svg:path.../>
tag, Inkscape is free to edit the individual points at will. In the end it did turn out to be a grouping problem even though I was only working with one path! Hope this helps others in similar situations.
Solution 4 - Svg
- Load your SVG in Method Draw http://editor.method.ac (File > Open Image)
- Ungroup your elements (Object > Ungroup elements) you might have to do this more than once.
- Select your path
- Reorient the path (Object > Reorient Paths).
- Save your image (File > Save Image) If it appears in a new window you can right click and "Save Image as..."
Solution 5 - Svg
Open your svg on Inkscape:
- Select the group that contains all those transforms you want to get rid off
- Press CTRL + U (ungroup)
- Press CTRL + G (group again)
This way you will get rid of the transforms applied to the group and they will get transferred to the paths that are contained within this group.
Solution 6 - Svg
For groups regrouping can do the job quickly. Select the group and press Ctrl+Shift+G (degroup) and then Ctrl+G (group).
For some objects who have a similar problem, spirals and stars for an example, the quick way is to press Ctrl+Alt+C (stroke to path) - this however converts the object to a pure path and removes all the extra-attributes, such as sodipodi:cx, sodipodi:revolutions and so on.

SVGO is an excellent open-source command line tool for this and a bunch of other optimisations. There's an equally excellent online web UI for it called SVGOMG
The relevant options in this case are moveGroupAttrsToElems
(SVGOMG: Move group attrs to elements
) to move transform
attributes from groups to path elements, plus convertPathData
(SVGOMG: Round/rewrite paths
) to flatten transform
into d
.

Whilst I prefer Inkscape, Affinity Designer (~$40 / Mac) saved me hours of effort when working with Android Vector Drawables.
Open an SVG, File -> Export -> SVG -> More -> Flatten transforms worked great.
Solution 9 - Svg
In my experience, if you're using Inkscape, it suffices to move the path element slightly (e.g. with cursor keys), and Inkscape will delete the transform attribute and adjust the path data accordingly. (Annoying if you actually want to keep the transform attribute.)
So, you could simply select the path (make sure it's the path and not the surrounding group), hit the right and the left cursor key, and you're done.
Solution 10 - Svg
It should be mentioned that there is the "Optimized" mode in preferences:
Inkscape Preferences > Transforms > Store transformation > Optimized
Which is supposed to minimise the occurrence of transform
attributes as much as possible, (but doesn't).
This seems to be on by default anyway.
According to a discussion, one instance where this Optimized mode lacks zeal is when the page is resized. This causes a translate
transform to be applied to the layer <g>
element. It seems that evacuating the children to another layer is the best solution at the moment.
Solution 11 - Svg
Inkscape has the option to clear the transformation data but still leave the value of the object unmodified.
In Inkscape, select the object and 'Path' menu, 'Simplify'. Now, you will have the transformations removed.
Solution 12 - Svg
- Select the elements in question
- Object > Ungroup (repeat until everything is ungrouped; see XML editor for nested nodes)
- Path > Object to Path (converts polygons to paths)
- Object > Transform > Uncheck relative move > Apply
Solution 13 - Svg
In this case just add the translate to the m values for each child so -10.254587 + 10.75 = -0.504587 and -308.96875 + 345.43597 = 36.46722.
Since all the terms in the example are relative (i.e. lower case) that's all. If any were absolute (upper case) e.g. M or C they would have to be adjusted too.
For scale you'd basically multiply all the child values by the scale.
Solution 14 - Svg
To remove the transform attribute from a g
element (group) in Inkscape, you can to move the group to its final place, ungroup it and then regroup all elements. Now a new group has been created, and if you don't move it again, it will not get a transform attribute attached to it.
Solution 15 - Svg
If anyone lands here looking for a solution to do this in Sketch 3, select the layer and then click on Layer->Paths->Flatten.
Solution 16 - Svg
In my case saving as optimized SVG solved the problem. So in Inkscape use:
File -> Save as... -> Optimized SVG.
Solution 17 - Svg
Found it:
- Set your desired page size*
- If your current layer has a transform (check with the XML editor, it's the top group under the SVG element) then create a new layer and move all objects to it
- Ungroup any groups (this may not be needed, YMMV)
- Select all objects and apply a null transform (such as scale by 100% 100%, or arrow right + arrow left) while having Store transformation: Optimized in Preferences / Transforms
- If you had to undo any groups, you can now regroup them
- Save a copy as Optimized SVG and set your desired numeric precision
*: Or at least place the objects where you need them, relative to the top left corner of the page. It's unfortunate that SVG coordinates reference the top left corner, while Inkscape resizes the page relative to the bottom left!

I was able to get rid of a matrix(...)
transform (due to mirroring) by combining the path with a rectangle and then removing the nodes of the rectangle. The translate(...)
part stayed though.
Solution 19 - Svg
This works if you are using Inkscape:
- Select everything and ungroup
- Save as "Optimised Svg (*.svg)"
In all cases I have tried, this has remove any transform attributes. Not sure if it works for more complex SVG.

I tried the solution posted here, namely to remove the group tags in the SVG-file and reopen it in Inkscape (0.48.3.1 in my case). Alas, after I translated the paths again using the select and transform mode (F1) and saved it, the group tags reappeared! Inkscape saves all transformations applied to the path in a surrounding group element. Unless you use the path-node selection tool (F2), hit ctrl+a and move the nodes of the path to their right place. After I had done this instead and saved afterwards Inkscape didn't add the group tags, because this translation applied directly to the path model. Hope this helps.

Ive been having this issue for years. The solution is clearly to be able to dynamically play with transforms in the browser, if its not going to be "fixed" in inkscape.
A user Mc at Inkscape forums gave me this solution.
The solution builds the current transform between an SVG element and its SVG root element, and then returns a full set of BBox information based on the total of the transforms.
It would also be possible to easily change which element the calculations are relative to, should you want to do in browser work between two parts of the same SVG file.
Finally I can actually have a panning SVG viewport.

In my case the groups are actually caused by layers. Deleting all layers in the document removed the group and transform (possibly combined with ungrouping objects and regrouping them etc as in https://stackoverflow.com/questions/13329125/removing-transforms-in-svg-files#answer-35490189 (answer-35490189 from @Charlie above))
Solution 23 - Svg
My specific problem was with symbols that were defined outside the page, thus requiring a transformation to be shown on the page.
To move the symbols to the page without requiring a transformation, I had to go through these steps in Inkscape:
- Open the Symbols window (Shift+Ctrl+Y)
- Remove the symbol from the document library. (There's a button for that in the window.)
- Now the graphic shows up in the document, outside the page boundary.
- Ungroup the graphic. (This is a vital step!)
- Move the graphic inside the page boundary.
- Add the graphic back to the symbol library.

This seems random, but nothing else I tried worked, so here you go random other person. Some of my paths had a sort of margin around them that could only be seen when selecting them (). I think this was created when I pasted a layer from another inkscape file and rotated it 90 deg. This made a pattern fill on the shapes have a different transform (lines spaced further apart). It also made align objects not work as expected. Using the Apply Transform mentioned by @Piotr_cz fixed the transform problem, but the strange margin remained. I accidentally got rid of it by changing the Blur on Stroke to any value and changing it back to zero.

Somehow I had no luck with any of the approaches. If there is <defs>
section in your svg and usages like this:
<g transform="matrix( *** ) "><use xlink:href="#***"/></g>
you may have to delete all usages and take everything out from defs section. Then, you can use inkscape to place it all in the correct way and then apply transforms using the mentioned plugin. Hope it helps someone.

Inkscape 1.0 on Kubuntu 20.04
Although this thread is rather old, I'd like to post my experience/solution. I came across this problem when trying to create a template for FreeCAD's TechDrawing workbench. These templates must not contain any transforms.
In my case I had to add a company logo from an external .svg file (entirely made with Inkscape). That logo contains graphic as well as text elements. When copying that logo into the template, transforms were created, that caused the template not to work correctly in FreeCAD.
-
First, this solution suggested on www.freecadweb.org/... does not work for me. That's why I searched the web and found this discussion.
-
Second, none of the solutions suggested above did work for me, but they put me on the right track. Charlie's answer came close, but Object > Transform > Uncheck relative move > Apply did show no difference.
What worked for me was:
- As mentioned by others, ungroup everything.
- Convert text objects to path - that seemed to be essential in my case!
- Delete all existing transforms in the xml-Editor and observe what happens with the related objects. In my case, the corresponding elements changed their position.
- Correct these changes manually but do not group anything.
- Save as normal svg (normal = no optimisation or other special settings were used)
Works fine when I use that template in FreeCAD.
One strange detail: Although my solution connotes that text elements were the problem in my case, it cannot be that easy. In fact, the base document (the one into which I copied the logo) contains a lot of text elements, and I did not convert any of them. So it could be the combination of "external source" and text elements. I merely post this detail as a hint to others, who might have related problems.
