.JPEG VS .BMP

[lordroba]

hey

I have this friend and we are arguing over what has better quality, a Jpeg or Bmp picture. I'm saying that it's .bmp because it retains the color information of every pixel, but he insists that it's jpeg becuase all internet pictures are in .jpeg format becuase they have more 'detail'.

This friend of mine also claims that jpeg images have more definition because, I quote "if u look at a jpg pixel, it fades into the pixels next to it". Which is saying that the color changes as you move along the pixel. I don't know how that would work...

Anyways I just want to settle the score. What's higher quality, jpeg or bmp regardless of file size and assuming that you have the same source picture.

bmp is less lossy, but they both suck

and a pixel has 1 damn color. you can't have a gradient in a pixel (can't fade from one color to another)

PNG FOR LIFE!!!

Uhm, what? Unless you're forcing downsampling, a BMP is lossless.

A PNG, for that matter, is a compressed BMP.

Your friend is a moron. Kill him.

Internet pictures are often in .jpeg format because a) people got used to it and b) they are SMALLER than bitmaps. It's not about quality or detail so much as storage space and bandwidth, which... well, used to be important.

Sarah said it best, your friend is a moron.

JPGs are used in html because of the efficiency of downloading a JPG vs downloading a BMP in a dialup scenario. Hence why a lot of people use GIFs and JPGs. That, and GIFs provide motion pictures too. It's not a matter of quality at the time, it was more of a matter based on compression.

[Keeper of Hellfire]

BMP is simply a senseless waste of space and bandwidth. Any other lossless format with 24 bit color depth is much better. And it is a common misconception that JPEG is always lossy. If compressed with quantizer 1, JPEG is lossless too.

let me sneak into the conversation here u.u

what about TARGA images?

[Zarxrax]

TARGA is another bitmap file format, similar to .BMP.
