Hi jeejee!
The BMP (Bit Mapped Picture) is an image file which hasn't compression so this file is of good quality but weighs much because it keeps all color information.
The JPG or JPEG (Joint Photographic Experts Group) is the most common format used and it has compression. Its quality and size depends on the degree of compression that you give to the image when you save it.
Finally, the most important feature of the PNG (Portable Network Graphic) is keep the alpha channel of the image so that the image save its transparency something that the others formats isn't.
.
Regards! :cool:
I hope that I have been able to help you

Rocky, Brilliant description of the file formats, but they are the most popular formats, any graphics current program can handle and also
lets save them in a different format.

BMP = Bitmap File (Uncompressed file, create by coloring the pixel)
JPEG = Joint Photography Expert Group (Compressed file, ZigZag compression applied, single layer, low size, web supported)
PNG = Portable Network Graphics (Non Compressed, multilayer, web supported)

PNG is a for web, and good for print design, when you want some Flyers to work on a Photoshop, you have a PNG transparenty logo

The Giff is too transparency if you go Save for Web&Devices in a Photoshop too, it can be, if you work some in a transparent layer and saving as Giff

The explanations are very good and better with adding the GIF format, the next question will be, what is the most efficient and compatible?

GIF = Graphical Interface Format ;)

What is the most efficient and compatible?
File Type Efficiency Compatibility
BMP 100% 30%
JPEG 80% 100%
PNG 98% 100%
GIF 70% 98%

Find your values, it depends on your need and the Next Question will be?
Which file types will be use in future and which files are just a relics?

Please remember ... vector file format is your most important file format for clients even if they can not themselves open the file. Vector file is the file they ALWAYS need to keep and or put away for future needs. You can size vector files from very tiny to very large with NO loss of quality.

Another thing to remember when designers submit their final source files after winning a contest, always make sure your last and final download has the vector file with no background. When the client can not open or work an AI file or eps file, they can still open the file in raster programs but .... if your final file has a background then that background color opens along with the logo and the end result is the client does not have a transparent file to work with. Same goes when you have several color version in same vector file, the ch goes to open the vector file with many versions, when it is opened in raster program you do not just have the one logo you have ALL of the color versions. This makes the files not usable to the client.

Yes, Sharie are right, but here opens another great discussion, since each program that works with vectors has its own file format, will be *. ai because it dominates the market or the *. EPS is more oldie or to position itself as more compatible *.PDF without forget how to get involved with the print

AGT it doesn't matter if EPS is oldie it is still a vector format and all logos are required to be created as vector format no matter if it is AI or EPS, pdf is fine as long as the file being saved as pdf is an original completely editable vector file

Is there any reason not to give the CH both an AI and a EPS file?
