google chrome - Why do my svg look so bad? -


my svg looks bad in google chrome , firefox too, svg borders have poor quality:

meanwhile, in illustrator svg looks awesome:

i have saved .svg file configuration:

what happened?

if svg has lot of horizontal and/or vertical lines, can improve appearance aligning coordinates pixel grid. i'll give example:

effects of pixel alignment in svgs

here 3 svg images made of rounded rectangles. (the source code these images pasted below.)

  • in (a), rectangle coordinates aren't aligned pixel grid @ all. result, of lines clear , sharp while others fuzzy , bit darker.

  • in (b), rectangle coordinates snapped integer values, giving them uniform appearance. however, fuzzy now, because antialiasing spreads each line across width of 2 pixels.

  • in (c), coordinates snapped integer values and given additional offset of 0.5 pixels in x , y directions. should able see definite improvement here.

if you're working in illustrator, try viewing artwork @ 100% in "pixel preview" mode.

i recommend not using stroke widths smaller 1 pixel. if want simulate thinner lines, try reducing opacity instead.
