Do you see the difference? There isn't any quality wise.
Also bitmaps load from the bottom up. :buddy:[/QUOTE]
I see a difference, look at the red no box on the jpg one, it seems engraved.
Audiophiles pissed me off, but now videophiles? Fuck

Yeah, I was taught this at work experience for web design on how to balance quality with loading times. :rolleye: He mentions that JPG can be changed anyways.

Still a lot more decent than mspaint's compression method.

[QUOTE=HubmaN;16241852]Actually, I don't think BMP's better in terms of compatibility.[/QUOTE]
When I talked about .BMP's compatibility I didn't mean like web browsers. If you have a web browser that doesn't support .PNG, .BMP, and .JPG and you're [I]not[/I] on a mobile phone you need to get with the picture.
But it's better for other reasons. I wasn't really sure about it so I copied that little bit from wikipedia. [I]Just that bit.[/I] The rest I typed up and it took ages.
[QUOTE=GiacJr;16236317]this is an example of a .png. the bad quality is due to it being from justin.tv.

There is a small difference, as another guy said, see the red "No".
Also not to mention the PNG being half the size of the JPG :rolleyes:
Also about all the fancy features of PNG, if a person planned to use those things, they probably already know the formats.

By the way that's a PNG. I just saved the JPG field as a .PNG so that it would get obvious compression, then edited it back into the PNG and saved as another PNG. It was all a little joke.
And I didn't use Paint. I think I used heavier compression than Paint uses.
I once saved a 6400x6400 BMP image. It was 120 mb. I converted it to png and it was 1.2 mb. HOW AWESOME IS THAT

PNG? JPG? Screw them all!
The best image format is .TXT, objectively.

[QUOTE=Uberslug;16233178]Not all JPGs have compression. If you just save them in photoshop at high quality there's no visible compression.[/QUOTE]
Wrong there is still compression it's just not noticable.
Notice how on max settings the compression isn't very good, but as soon as you go to 8 or "high quality" suddenly the filesize drops dramatically.
Also JPG is not lossless compression, it's lossy (you have it set to "Yes" under lossless)
PNG is not lossy, it is lossless.
BMP doesn't use compression at all, it's the raw pixel data.
However BMP isn't used for... well anything these days, most people who produce graphics will save their files as a .tiff format, which is also uncompressed but far better in terms of read speed and it supports stuff like transparency.
You should have compaired it against GIF in that case.
PNG's though are the best to use for most things on the internet, unless you really want to save on bandwidth or have a very large picture to show online (JPG can handle larger file sizes better than PNG can, unless the PNG file is full of solid areas of color).
The way PNG works is it reads the image in horizontal rows. So for instance, if the top row of pixels in an image is nothing but the same blue color, the only data that gets saved would be something like "row 1: blue", which allows for a high level of compression without loosing information
However if using a picture, and there's about a thousand different pixels for row one it will get saved so it reads the image in a way such as "row 1: blue, red, green, etc x1000...".
It still gets compressed fairly well using this method but not nearly as well as JPG, but with JPG you will loose quality.
Already knew it, but it made me thinking something.
I use .png for everything. :smug:

Yeah man, let's save a 1000x1000 pixel art map as a .bmp,
5mb minimum.

Actually it would be around 3MB - 1 million pixels*3byte/pixel=~3MB :eng101:
It looks like some people here don't understand what the word "uncompressed" means, including the OP. Reducing the file size in any way, with or without loss of quality is compression. Png IS compressed, while its compression is lossless, jpeg is compressed with lossy compression and BMP is uncompressed.

[quote=OP].PNG files are compressed. But in a different way from .JPG files. They utilize lossless compression, meaning that they do not reduce quality, but still reduce file size. .JPG files also use lossless compression, but in addition, they use lossy compression.
In general, .PNG files are larger than .JPGs, with better quality.[/quote]
wat
Why does .bmp even exist?
[QUOTE=mixshifter;16250078]Why does .bmp even exist?[/QUOTE]
For compatibility and programming reasons. If you look in your Windows folder, all the images are BMPs.
[QUOTE=Elecbullet;16250132]For compatibility reasons. If you look in your Windows folder, all the images are BMPs.[/QUOTE]
It's also extremely basic with just X, Y coordinates and color.
Oh.
Very well then. BMP shouldn't be the default save option in Paint, I always accidentally save avatars and stuff as .bmp and not realize it until later.
Tiff is for the extreme hardcore guys such as myself.
I have a Tiff picture of one of my childhood drawings, the scanner made it around 12000x16000 or some crazy shit, no compression and ultra high quality, only 2.5GB. But I can't even open the picture without Windows locking up for 2 minutes.
Relatively good guide. But you split it into too many sections without really having to.

It's for printing with excellent quality with an actually good photo printer, not the shit you buy for your home. When you need to have a uncompressed image with a small as possible size.
But JPEG at MAX will usually do justice unless you really need it to be P-E-R-F-E-C-T.
[QUOTE=decemberists;16236062]no .tga is for sprites[/QUOTE]
It's different. TGA is probably the norm, but a lot of retro games uses BMP. If I remember right then Icytower uses BMP.
I gave you a rainbow cause I like rainbows and I think you'd make a pretty rainbow.
[QUOTE=smurfy;16241909]But what about animated PNGs? That's the big thing now.[/QUOTE]
It's like GIF, just with a lot of colours instead of a limit of 256. (Unless you use 8-bit PNG then it's basically the same thing, but better.) Thus it also becomes bigger in terms of size.
[QUOTE=BrainDeath;16242668]I see a difference, look at the red no box on the jpg one, it seems engraved.[/QUOTE]
OP obviously saved in HIGH and not MAX with his JPEG.
[QUOTE=KorJax;16243096]Notice how on max settings the compression isn't very good, but as soon as you go to 8 or "high quality" suddenly the filesize drops dramatically.[/QUOTE]
Indeed. You can see the compression if you adjust the levels of the image (and hold in alt when draggin the triangle along the graph), but visually there is no compression.
[QUOTE=IDTL;16232753]My favorite is .png.
Lossless, transparency, and can do animations. (.apng)

[QUOTE=Elecbullet;16250050]wat[/QUOTE]
Except JPG isn't lossless, it's [B]only [/B]lossy. Lossy = the compression involves loosing quality to get the result. Lossless = no image/color information is discarded during compression, at the cost of a higher file size.
i always use png
I use PNG no matter what because I don't give a fuck.
lol at that thread. Bumpworthy.
.jpg is fucking worthless. I use it for nothing because I always see the artifacts and I fucking rage.
I'll take the slightly larger file size (which is barely fucking larger) for a way better image quality.
All my work is done in PNG. Even my avatar is in shiny PNG.
Don't forget, Photoshop also has the ability to customize the colour pallets used in these formats. You can strip down some bytes by not using certain colours.
