Specs: Windows 7, don't know
I've heard that pics in 'raster' format can be resized and still keep their details. So I'd like to know how, or if there is a program, that can convert jpg files into a raster format? I'm trying to do something for my dad:) Thanks in advance...

Apparently the term 'raster' comprises just about every picture format:

Here's some info about picture file compression:

For what you're trying to do you might want to convert the jpg to bmp. I think that's still the most common format to edit pictures. You can google jpg2bmp to find downloads for converters.

What software do you have for resizing?

maybe I could send you or someone the pic and you could resize and send back? It's an image of a decal ... my dad loves putting together model airplanes etc, and wants a specific image/decal for one of his models ... I have a pic of it but don't know how to replicate it in such a tiny way ...

You might want to experiment with Paint since it's already on your computer. You can do some resizing with it. It's best to have more than one copy of the original as often after editing a person will save it but not as a separate file so they end up copying over the original with the edited one.

But is it true that an image in 'raster' format can be resized either huge or tiny and still keep its detail? And if so, how can I take a jpg and change it into raster, then resize it?

As far as I know, from my link in # 1, 'raster' is a generic term for most (all?) digital formats so there is no 'changing' to raster format. But I'm kind of new to that concept so if you can provide links to a different explanation I'd be interested.

If you blow up a jpg enough you'll get a screen full of blocks as each pixel is stretched. When you enlarge a picture you're not putting any new information into it but yet you're making it larger. The resolution is going to suffer. I guess there is software that allows you to increase the pixels/DPI but what it adds is just an educated guess and it won't be as good as if the original picture was taken at that resolution. There's a discussion of that here:

http://photo.stackexchange.com/ques...

with a link to something called 'perfect resize'.

I still recommend you convert the jpg to bmp and edit it with Paint. Reducing an image doesn't involve nearly as many problems as expanding it so you may be able to do what you want with Paint.
