This may have already been answered here somewhere but I can't find a directly relevant thread.
What's the best method for resizing an image to comply with AusPhotography's 1024px long-edge limit AND 250kb filesize?
When I select 1024px as my long-edge, the filesize still comes out to around 350kb. I'm compensating in PS3 by saving to JPEG with a quality of about 8 or 9 (out of maximum 12). But I'm not sure if this is compromising the image or not.
What is the best approach that you take for resizing (reducing) and retaining best quality (and getting under the 250kb limit).
