PNG vs. WEBP: What's the Difference?

You know how you can save your drawings on the computer? Well, there are different ways to save them. Today let's learn about two types - PNG and WEBP. They're like different boxes you can put your pictures in!

What is PNG?

PNG is like a special art folder that keeps your drawings looking perfect. It's great because:

  • Your pictures stay super clear, just like when you first drew them
  • You can make parts see-through (like when you draw a ghost!) But there's one thing - these picture files can be kinda big, like a heavy backpack full of books.

What is WEBP?

WEBP is the new kid in town! Google made it to help pictures load faster on the internet. It's cool because:

  • It squishes pictures down to a smaller size (like a magic shrinking machine!)
  • They still look pretty good, just maybe not quite as perfect as PNG
  • Some really old computers might not know how to open them though

Which should you use?

If you're making:

  • A school project with logos or drawings → Use PNG
  • Pictures for a website → WEBP might be better

Fun fact: Did you know WEBP pictures can be up to 30% smaller than PNGs? That means websites load much faster!
