| Ive tried googling one, but does anybody know of a mass .png to .jpeg converter. All i can find are ones that do 1 file at a time, im looking for an exe that i just run and every .png in the folder is automaticly converted to .jpeg and the original overwritten or delted. | |||

| I don't believe any exist... And why would you want one? Unless something is of photorealistic quality or was originally saved as a JPG, PNG is a vastly superior file format... | |||

| My rocket computer is pretty old, actually. But it still doesn't mean mass conversion from PNG to JPG makes sense.
note: nonsensical is a word, but apparently sensical isn't. That sucks |

| The pictures in my layout were originally all going to be PNG’s, but there was some weird bug in IE that causes PNG backgrounds to be darker than they’re supposed to be, so I switched to JPG. In doing so, I discovered that the JPG’s were actually smaller than the PNG’s. However, one of my user bars is significantly smaller than the other, and it isn’t the Ultimate Dragon… (which is a JPG).
Okay, I had my sister resave the original file in Photoshop as a PNG, and it’s actually a couple thousand bytes bigger (although clearer), so now I’m dumbfounded.  |

| If an image has few colors, it'll do better as a gif or png. If it's got lots of colors - for example, it's a photograph - it'll do much better as a jpg. If you've got an image that's not a photo but you want to keep the right colors on IE, use gif, not jpg. In your case, you've got a photo, so jpg is better regardless. | |||

I’ve noticed that, when dealing with still images minipic size, it seems like BMP is better… is there a similar rule with that, or is BMP always better for that size? It’s just that I’ve seen people say that you should never use BMP’s over the internet, but that isn’t what my experience teaches me. |

| bmp is acceptable when it's that small, but realize that png is still going to be smaller almost all the time. | |||

| There should never, ever be an occasion where a gif, jpg, or png file is smaller than a bmp of the same dimensions.
Why? Because a bmp uses no compression at all. It just stores the raw RGB values for each and every pixel in the image. It's possible that at extremely small dimensions, there's enough overhead from the compression algorithms that it compressed files would make the file slightly larger, but it would be extremely insignificant and gif/jpg/png are all more universally compatible than bmp anyway. Also: I don't think a bmp would ever be smaller at 11x11. For the bmp, that's 121 pixels, each with three values from 0-255. A standard gif, on the other hand, would have a small color index and then just ONE value between 0-255 for each of the 121 pixels, specifying which index it is. And that's ignoring any other things gifs do to reduce file size. At small dimensions, pngs tend to be slightly larger than gifs, but as dimensions increase the advantage switches. |

| …Okay… I just saved a blank bitmap and a blank PNG (what does that stand for again?) in Paint (both 11x11), and the bitmap was 450 bytes while the PNG was only 158 bytes. So then I put in one pixel of each color in the palette Paint has… and the bitmap was the same size (this was to be expected), but the PNG was actually smaller (140 bytes)!
I know that in the past I’ve observed bitmaps of that size that were smaller than PNG’s though, I kept looking back and forth at each of them because I couldn’t believe it. |

| PNG = portable network graphic (I think one of either "network" or "graphic" is supposed to be plural, but I don't know which one so they both get to be lonely)
and if you had photoshop, you could do a batch conversion, but I'm guessing you don't have photoshop and can't do a batch conversion. |

Originally posted by m3gaman Irfanview does this, by simply pressing "b" in the main window (for batch). You can have it output to the same folder, delete the originals, even set the compression options and other things, and it doesn't even take that long. It's just if you actually want to download a very small, full featured image viewer, or not.  |

| Why not just... Open it in paint and save it as JPG? That works... |

| It would probably have low picture quality. Besides, he still wanted an easier way to convert a large amount of images at once, instead of one at a time. | |||
