I'm doing pixel art with grid tool, but when i save with pdf, i still see the grid. How i delete the grid?
It's not "the grid" - it is anti-aliasing between shapes - anti-aliasing is showing a pixel/half-a-pixel of the blue background.
If saving for web, use Art-Optimized anti-aliasing in the
Save for Web dialog window.
In many cases, simply adding a solid, single fill behind all the artwork will force AI to anti-alias to a correct color. In this case, I'd place a yellow fill behind the triangle shape to force AI to anti-alias to yellow rather than blue.
(Just a common issue with AI anti-aliasing -- nothing you're causing or doing wrong.)
As Scott has mentioned before me, this is the product of how Illustrator displays its anti-aliasing between shapes.
If you save your art as a pixel-based image file (JPEG, for example), you should find that the lines will disappear.
If you need the file as a PDF however, and you still see the lines when opening with a PDF reader, then there's only one way I can advise you to get rid of the lines.
- Select one of the squares
- Use the select similar command (you can find it in the top bar as this icon , or if you can't see it, you can also go to the top menu: Select > Same > Fill Color)
- From the pathfinder menu, select unite
This will combine all the squares of the color you selected into one shape, and so most of the annoying lines will disappear.
Repeat the same process with the rest of the colors, and you should have a nice clean shape.
