Generally, SVG files produced by vector editors contain a lot of unused elements and attributes that just blow up their size without providing better visible quality.
SVG Cleaner could help you to clean up your SVG files from unnecessary data. It has a lot of options for cleanup and optimization, works in batch mode, provides threaded processing on the multicore processors and basically does two things:
- removing elements and attributes that don't contribute to the final rendering;
- making those elements and attributes in use more compact.
Images cleaned by SVG Cleaner are typically 10-60 percent smaller than the original ones.
