What's the best file type to use for images when you convert them from .Psd to something Scratch can use? I've had problems with JPGs when the project is uploaded and want to know what the best kind is to use.

Doesn't .bmp have less compression and quality loss? The only problem I've had with those is that the colors change slightly.

I think.

.bmp and .png are the same except .bmp is larger and .png supports transparency.

Here's my opinion:
GIF's are huge files compared to the others, so only use them if you want animated pictures.
PNGs are rather good quality for their size, so they are my pick.
JPEGs can have lots of compression, but lose quality in the process.
I personally wouldn't use any other types of images (excluding vector images) on the web just because not all browsers will support them

Scratch only sees transparency if it's 1-bit, and it's in GIF format, so GIF get's my vote.

Personally, I like .bmp because I enjoy the discolored, gritty look your pictures obtain when converted to it.

Really, though, I think .png is the way to go.

*ahem*
.PNGs are lossless, meaning that no quality is lost. BMPs have NO compression whatsoever so the file size is MASSIVE. BMPs are also restricted to 16bpp -- no transparency support. PNGs, however, do not have this restriction, and support 32bpp images -- transparency and semi-transparency -- therefore making it the best image format available. Let's compare it to GIF:

GIF PNG
Animation: Animation No animation
Depth: 24bpp 32bpp
File size: Medium Small
Support: 100% IE has some issues

GIF is quite a competitor, but if you're going for quality, go for PNG. big_smile

Yeah, GIF loses too much quality and doesn't display all colors correctly so I'll go with PNG

well, GIFs don't really lose quality, they just have massive filesizes if the image is good quality

No, GIFs only support 256 colours so it does lose quality.

Genesix · 2012-08-01 14:07:56

Also, what color profile should I use? It gets annoying when I import it into Scratch and the colors are completely different.

Ehm ehm! 256 colours would mean 8-bit pictures... that's how many colours pre-millennium computers could support!

GIFs I believe have true colour support in their palette, with only 256 (yes) colours per frame.

Me neither. Maybe some browsers/OSes don't support it.

It's moving now. I was using chrome earlier- now I'm in firefox.
Must be a browser thing,

Yep. I did some research and "GIF intrinsically supports animated images. PNG supports animation only via unofficial extensions."

Furthermore, "Mozilla's unofficial APNG format is a potential solution"
So it makes sense smile
