Answer 1

JPEG is a picture, GIF is an image typically used on the internet (takes up less space than a jpeg), PNG is a newer technology that will take the place of GIF. Don't be too concerned with that stuff. The one most people use at home is JPEG or JPG (either). Some cameras have their own extensions which you have to convert to JPGs to send the picture to other people. Just about all computers can view JPGs. The other picture files you mentioned are more for computer people and you'll know if you need to develop one. There are sites that will help you for free.

Answer 2

Well, I've studied such things but I really can't remember what JPEG, PNG, and GIF stand for, but I can tell you what they for, and how to use them.

These three extensions are used for the Internet because they don't need a massive storage memory like the BMP one..

JPEG (Usually ***.jpg) is used for the images with a lot of variant color degrees, to produce a good quality images. (images of nature, animals, people,....)

GIF is used when you have an empty background, because JPEG doesn't support the empty backgrounds. It's also used for the animated pictures (it's the only one to support animated images such as those which are produced by ImageReady).

PNG supports the empty background, but can't be animated.

I use Photoshop and image ready, all what you have to do is:
Save as and to pick the proper extension, or use Save For Web.

Answer 3

The different kinds of images are pretty similar, but here are the differences that come to mind:
JPEG is sort of like the default image format. Every PC should be able to handle jpegs. They can be in B&W or RGB but can't handle transparency, layers, or vectors. They're always rectangular, and they take up a good amount of memory.

PNG is the most complicated file format, I believe. It can handle transparency, layers, and vectors. They can be in RGB or B&W. They are rectangular, but can appear otherwise if you use transparency around the image. PNG takes up a lot of memory.

GIF is the simplest format, I think. It can be indexed, B&W or RGB and handle transparency, but not very well They can't handle layers or vectors. I personally stay away from GIF but some people like them. I believe they take up less memory, especially when indexed, but are poorer quality images.

To convert, open an image in MS Paint and click "Save as...", then click on the file format dropdown menu (it should be under the bar where the image name is) and select whichever format you'd like the image to be.

Answer 4

You need a program like pgotoshop, photo suite, or any any of a bunch of similar image manipulation programs.

Different files have different sizes and different ideal resolutions.

JPGS are usually used to store raw images, or more often to load on the internet as images. The file small is small. To keep a jpg looking good, take the size down to about six inches at 72 dpi. This generates a small image that still looks good on screen. If you printed it however you would see the pixels.

For printing you want to make sure the resolution is 300 dpi. Save these as TIFs.

PNGs are often used in other formats, such as the texture in 3D art. picts are similar, they are small enough to use in the 3D environment.

PSD and TIF files can have a lot of channels. One for red, one for green, one for blue, then an fourth channel to use for transparency. These two formats can also have layers, but that's a bit complicated for this discussion.

EPS files are for printing typefaces and logos. They are vector graphic, you can make them bigger without any pixels appearing.

You should get yourself a copy of Real World Photoshop. It's a great book for people interested in such things, and has charts of all this kind of information.

Answer 5

A jpeg is usually used for photos and high quality images. GIFs tend to be animated or web quality images. I'm not sure about PNGs... i think it's for 3d imaging.

Oh, and yes, you can convert. Try using Photoshop, if you know how to use it.

Answer 6

I just gonna keep my answer short and sweet.

GIF- Good for screen viewing since its small and compact (compressed), but not printing.

JPEG- Good for screen and printing...BUT jpeg often produce large file since its not compressed.

PNG- Now PNG has both advantage from GIF and JPEG side. Its like the master.


For your photoshop, just open your photo File>Open and then once its open and you want to convert it to wtv format that you wanted, you just go to File>Save As, and then choose format from drop down menu and voila.

Try Google and figure it out yourself.
