It's saved as .png as default. Just open it up in Preview and go to File > Save As. Then pick JPEG in the format dropdown.fayans said:
Panther saves as PDF, Tiger as PNG.
You shouldn't save screenshots as JPEG anyway.
If you are interested in a 3rd-party solution:

TQ. I suppose I cannot change the default save format then.lexfuzo said:
Why not screenshot in JPEG? Mind to explain?
BTW, if I may ask : is there any simple freeware to reduce the size of screenshots for easy upload?

When I experienced that same inability to upload due to size limitations being exceeded, the reply I received was to use ImageShack (a hosting service). It may be your solution, but it did not work for me. Then again, I am using OS 9.1.
Tinkertool used to be able to change the screenshot format, don't know if it still does, as i haven't used it for a long time 
And as to shouldn't save screenshots as jpeg... umm... i can't think of a reason, unless you need pixel perfect shots, then bmp would be the way to go lol
Lastly, i found a small app to batch resize images on macupdate i think, no idea what it was called, but a search should bring something up without too much trouble

Sure.fayans said:
JPEG and PNG use different algorithms for compression:
JPEG compresses block-wise under loss of information.
PNG compresses lossless, more or less the same way ZIP does.
JPEG is best suited for images with gradients, photographs for example. It is not very good when you have sharp lines on your image.
PNG preserves the sharp edges, but it is not as efficient on gradients as JPEG.
A typical screenshot has lots of straight lines, text (!) and areas of uniform color. Take this site as an example. Therefore PNG gives the better result.
Try it for yourself: Take a screenshot, save it as JPEG and magnify the result. You'll see rectangular feathering around oblique lines that should be crisp. The bigger the compression, the stronger the effect.
You may use JPEG for screenshots, of course, and maybe not even notice a visible difference to PNG, but in theory PNG gives the better result.
The JPEG2000 format aims at combining the advantages of the two others.

There's some discussion on changing the default format here as well:

It ranges from an unconfirmed
to some AppleScript.
