I just released www.cloudformz.com, It's an advanced formbuilder (Dutch) and the whole theme is that it's a cloud service.
So,how surprising, I use a cloud background (1920 x 1080). My question is, how can I get the filesize smaller, but the same quality.
I am aware of the quality slider when exporting for web, but that decreases the quality sow much that you see artifacts.
Thanks in advance.
Internet users expecting to use "cloud" services would normally be fairly well connected to the Internet, no?
Your background image, http://www.cloudformz.com/img/bg.jpg, is only 64 kbytes. That's already almost inconsequentially small for an image that size... It's a fairly highly compressed JPEG with no color profile info or metadata in it. I don't think you're going to get it much smaller than that without seeing quality loss.
However, one thing to try, with a large graphic containing open spaces and pure, solid colors, would be to save as a PNG, which can be very efficient for such files. However, any noise or gradients in the image at all will cause a big increase in size.
