Thanks in advance!

If I'm correct:

1). Basically it does something (I don't know.) to cut down on the file size of a project. I remember hearing that compressing matched similar values and such, but I'm no expert.

2). It makes the images a bit lower quality, though that's all I know of.

3). If your project is huge, then yes, though make sure that your project doesn't have any shading (via. paint bucket) or else Scratch will give you an error.

I hope that this answers your questions!

It means that Scratch will try to make the file size of your sounds and images smaller.

-How does it affect the sounds and images in my project?

Compression can cause the sound and images in a Scratch project to be of lesser quality. Images can become blurry and sounds can have background noise. Bigger sound files and bigger images are more likely to be compressed than smaller ones.

Most Scratch projects still look and sound okay even after compression. If you're uploading something that relies heavily on graphics (like a project that relies on color sensing, or an art slide show) or sound (like a recording that has background noise already), then you might want the box unchecked. Otherwise, it's okay to leave the box checked.
