Zoom in and observe the blurry lines | With a higher resolution, it takes much more zooming for the lines to blur | PNG does not "blur" details. After zooming enough, you start to see the pixels. For line drawings and high contrast images, PNG is better than JPG | SVG does not show any pixelation at any zooming level, which makes it the most appropriate format for line drawings. (Depending on the browser you use, you might see some pixelation due to how the browser renders the image) |
