I have downloaded a 1.01 GB .zip file, which, contained thousands of BMPs. When I extracted these images using UltimateZip, I opened the images using Paint Shop Pro 7 and saved them as JPEGs. I then continued to the same for each folder within the archive and found I have basically 'compressed' up to 30-50 times. After this was done to every image I then recompiled the folders and archived it to .zip format, the result was that it finished to about 100MB.
Why do people insist that BMPs are that much better than JPEGs, when there visible quality differences are almost hardly visible? Large files on the eMule network have a larger chance of becoming corrupted.
I reviewed the differences of the file I downloaded and could not genuinely tell the differences between the JPEG and the BMP.
Anyone encountered the same situation?

The big difference i notice (apart from the size) between JPEG and BMP is that jpeg doesnt handle some colours very well at all red been the one you will notice the most(it turns it into somet weird pixlated brown sometimes) i do think bmp is still much better i wouldnt download a comic in jpeg format.

Yeh, jpeg is simpler and bmp is just the ultimate uncompressed format. You should use irfanview - it's an imageviewer and a batch converter = much easier than separate converting. Bmp is usually the formate used for separate rasterized layers in adobe ps which makes the psds so goddamn big. I hate bitmaps though.

I've noticed only in one picture that I downloaded within this .zip file a very slight difference. I viewed all pictures using IrfanView, IE and PSP. But after a few tries I never bothered because I was happy with the image quality after conversion.Originally Posted by .:sp00ky:.
But I didn't think it was considering how much longer I had to wait for the damn thing to download! lol
Nor would I. So much better to use JPEGs for a wider usage when BMPs are restricted, and I don't fancy burning to DVDs until I have a new DVD burner :p

... sorry but PNG is really better. It's larger filesize, but better quality and MUCH smaller than BMP.
i typically use jpeg for photos...and png for everything else. (it's especially good for screenshots)

Interesting point about PNGs. When I did my conversions the only real difference was when I tried converting BMPs to GIFs.

PNG-24 is superior to JPG imho, and PNG-8 gives GIF a run for its money. PNGCRUSH gets the best size out of the photo, too.

bmp is better, but jpeg wins due to size
Bmp by far is the best quality, but i still don't like it. PNG is best, then JPEG. <--In my opinion of course because you can have good quality transparency.

bmp's are lossless, jpg's are lossy.
It's like a 320k mp3... sounds great, but still not quite as good as the original.
The difference in this notorious screenshot is quite noticeable, especially the lettering.

You have no chance to survive make your time.
Because BMPs are lossless. PNG is the next best thing tho, since it preserves transparency.
I'll bite.
A gigabyte of what kind of pictures?
