I wrote on FB they told me to come here lol. I make t-shirts and the size needs to be 4500 x 5400 px 300 dpi and less then 20 MB. I have never had a problem till I tried something new and now the size is right and the file size is way to big. I thought it would be the right size as long as the dimension were correct live and learn. This seems so simple but it is way to big of a file. Is there a way to keep this size and make the file part smaller. In this picture I was just messing around and used the stuff from pixabay and like what it looked like. 1 horse line drawing 3 watercolor png files oh the horse is png also. The file come out to be little over 38 MB. Hope someone can help thank you ahead of time:) 

 

I tried to upload a file (picture) but it is to big LOL. 38 MB

Does the file format have to be PNG? That’s fine for the line drawing, but with the colour variations in a watercolour you won’t be able to get the file down sufficiently unless you go for a lossy format such as JPEG.

Yes it is PNG I had to forget what I was doing , but I did manage to do something else similar. Thank you so much for your help new to this and learning so much. Thank you again:)
