Why are my files always huge? I have a picture right here under 640 in every dimension that's almost 500kb.

What format are you saving them in?

If you're using Photoshop, try using the "Save for Web" function and see if that helps.

I am using Photoshop.

What difference does save for web make the the picture quality?

Edit: it seems like it just changes it into a gif.

It will save them as Jpegs to. You just have to select that option in the save for web dialog window.

I see that now, haha. Ty.

Is this the only way to make a file smaller without sacrificing quality? Because it's still about 250kb.

No. But just use the slider in that window to give you the best possible quality at that size.

LOL - I also use to battle with this image size and quality thing - first challenge entry I cropped the original until I got to the correct file size - needless to say the result was grainy, out of focus and not very good.
It was suppose to

but resulted in

You can find this under the learn menu. Then just click tutorials. Lots of useful stuff there.

You can also use the "Optimize to file size" option to tell PS what size you want and it will automatically select the best settings to get that size.

rex: thanks, but that doesn't really say anything new.

thegrandwazoo: does that mean there's snother way, otehr than save for web?

There is another way heartbreaker .. use a different programme ... guess what similar if not same result. Any time you compress on saving you lose some quality .. but at least it is the right size (bits wise) and the right size (pixel wise).

edit to add: once you compress file size your picture may need a sharpen .. at least once.

If that tutorial doesn't work for you then you are missing something in it.

You can always do what I do....I edit the photo in PS and then save it as a "10" quality and then re-open it in GIMP which allows for much smaller increments of compression when re-saving it. I simply adjust it until it hits 150kb....usually it's around a 92 or so on a scale of 100.

This isn't the easiest way...but it's what I do, and often I find it produces a little better quality of photo, but maybe that's just me being wierd, lol.

Anywho....just a thought.
