title: What are the different usecases of PNG vs. GIF vs. JPEG vs. SVG?
body: <p>When should certain image file types be used when building websites or interfaces, etc?</p>
  
  <p>What are their points of strength and weakness?</p>
  
  <p>I know that PNG &amp; GIF are lossless, while JPEG is lossy.<br>
  But what is the main difference between PNG &amp; GIF?<br>
  Why should I prefer one over the other?
  What is SVG and when should I use it?</p>
  
  <p>If you don't care about each and every pixel, should you always use JPEG since it's the "lightest" one?</p>
