Need to have possibility to save .JPEG 300 DPI 50"x50" not more than 100mb
I am trying to save 300 dpi 50"x50" picture for Printify/Etsy
and it’s saves it in more than 100mb. But Printify MB size must not be more than 100Mb.
Help, please.
A 15000x15000 pixel jpeg can easily be under 100MB if you take the quality slider down a little in the export options when saving (you have to select jpeg as the format to see the quality slider).
Your image has no dpi because it is fully digital. It will only get a pixel density in “dots per inch” if you print it. Before printing it only has dots - well: pixels. But not “per inch”. 
Depending on the file format that you save as, the bigger the file size is for your image.
I would recommend saving as a JPEG and turning the quality slider until you get under the file size you need. Similar to what @alanhusband-677420 said.
