# Cool Image
```My friend told me he found a really cool image, but I couldn't open it. Can you help me access the image?```
We're given a PDF, but we're told that it's an image. Additionally, if we check the magic number, we can see that it's a png.
```$ xxd cool.pdf | head -n 100000000: 8950 4e47 0d0a 1a0a 0000 000d 4948 4452  .PNG........IHDR```
We can go ahead and just view it by changing the extension.
```$ cp cool.pdf cool.png```
