Is there a tool to convert SVG line paths from absolute to relative?

Question

Looking for a tool to convert something like

M10 20L0 0 5 5 10 10

from the absolute position to relative, something like:

M10 20l-10 -20 5 5 5 5

Notice the uppercase L for absolute and lowercase l for relative?

Answer 1

1. Open Inkscape and select, File, Inkscape Preferences (or Shift + Ctrl + P )
2. Select SVG output

3. In the path data section untick Allow relative coordinates or select always use absolute coordinates depending on your version of inkscape.

   This will only affect newly created paths, or existing objects for which a rewrite of the path data is triggered. For existing paths

4. Select Edit, then Select All in All Layers'.

5. Use the arrow key to nudge the selection(e.g. one step up and one back down again). This will trigger a rewrite of the path data in 'd' which will follow the changed preferences for absolute path values.

This works for inkscape 0.48

Answer 2

For who's still searching for this tool. There is one made by Lea Verou on codepen that convert paths to relative or absolute.

Example convert this:
