My picture is 1536 pixels W and 2048 pixels H, how do I convert it to be between 3MB (3000KB) and 10 MB (100000 KB)?

Thank you very much in advance. I have Gimp.

What file type?


I would divide the target file size by the current file size (say, 8MB/15MB). The result to that equation is the percentage by which I'd shrink the image. (In this instance, .53 or 53% of its original size.)

Is this for print? If it is, the ppi shouldn't be lower than 180, and unless you are printing professionally, you don't need anything over 300 unless you are planning to enlarge it. Those would just be extra pixels. But if it's for online use, you can lower the the resolution to 72. The final format also makes a difference. What extension are you using? I don't use GIMP, but in Photoshop you can lower the output quality in the 'save as' dialogue box (or 'save for web' optimizer), and I would guess that GIMP has something similar? So, basically, lower your image size or resolution to get a smaller file size.
