Convert tiff to jpg

[alex_lu]

Hello everyone,

I would like to transform tiff images to jpg format. My client has given a copy of javascript they have done. It basically only does -resize and change the file extension name to jpg. The problem I've got is file size of the transform images. The file size of them are around 500 - 700k, which is too large. If I use photoshop, they come out around 20k. I've been trying -resample, -scale, -quality 50, and -depth 8. None of this seem to reduce the file size.

Could anyone help, please? Many thanks in advance
