Resampling image help please!

[NTC Ann]

The Art Assoc. this year is using Zapp instead of Juried Art Services.
They require min. 1400 pixels (mine is 1400 x 1400) but less than 5 mb.

No matter what I do, to get less than 5 mb = 1320 x 1320 OR if 1400x1400 = 5.61 mb.

I've tried changing in Photoshop, tried their Pixlr.com/editor

I've tried lowering resolution, lowering quality... but when I open the image after, is still 5.61 mb

No matter what I do, I can not get to their minimum 1400x1400 and less than 5 mb.
1400x1400 pixels always ends up 5.61 mg. And they actually want 1920 pixels at the longest side (so 1920x1920 ends up like 7.91 mb.

Can anyone help please?

Hi,

What file type are you saving your image as?

[NTC Ann]

Jpeg

Increase jpeg compression. If that doesn't help, your file probably has excessive metadata. Using Export or Save For Web will strip that out (remember to check Embed Color Profile).
