How do I make a jpeg smaller without background?

Lets say I have a 2mb jpeg and I want to make smaller like under 100kb. When I do so I can't avoid making a background. How do I downsize the file without adding a background. In other words I want the new small file to just have the picture appear in Vegas not the black background.

Do you mean smaller file size but same size image? Open the image in an image editor and save as .jpg, but adjust the quality down. This will get you a higher compression, resulting in a smaller file. Was that what you wanted?

ok so you want a small file with no background. meaning if the background is white you want the white parts transparent. youll need an image editing proggy. erase the white BG and save it as GIF coz i dont think JPG supports transparency.

Or you could create a separate mask or embed an alpha channel in a 32bit TGA file to create the transparent area.

I transfered to make smaller files and its still freezing up. now im going to try to change jpegs to .png files.

scenerio: My church has a tv program and we want to have our 14 booklets presented in one frame. I have moving clouds and when I put about 4 booklet covers on screen it starts to slow down big time. The problem is I want to show 14. I use pan to shrink booklets then use motion for placement. Then everytime when rendering about half way through my computer freezes up....very frustrating. What can this be?
I have tried everything this thread has suggested exept now I'm changing file names.

The problem is fixed!!! It could be one of two things. I changed all jpeg files to bmp. and defragmented my drive. Now no more freezing!!!!!!!!

Randini, just a curious question, but why use both pan/crop and track motion? You can resize and place images in the frame with either function. If you only used one function instead of both it might render faster and easier.

Chien,
Originally I did only use motion but I was told that I should use as less Motion as possible so this is why I used pan to shrienk image then motion to move it.
You might be right though.
However, now my computer does not freeze up....but....LOL....that is when I used a streaming render but unfortunately now it still freezes up when I render to ntsc (window)...Yikes!

PS computer freezes are the worst!!!!!!!!!
