Klaviyo recommends full-width email images between 600 and 1,000 pixels wide and under 2,000 pixels high, and files of 1 MB or less. Herofab's square 2K output is 2,048 × 2,048 pixels, larger on both sides, so it has to be resized before upload; the JPG download is the lighter file. Klaviyo suggests inserting an image at twice its display size, which is 1,200 pixels for a 600-pixel template; 2K output is wider than that. ### Resize before upload Square 2K output is 2,048 × 2,048 pixels, above the 600 to 1,000 pixels wide and under 2,000 high Klaviyo recommends. ### Lighter as JPG Klaviyo recommends files of 1 MB or less; the JPG download is lighter than the PNG. ### Enough for 2x Twice a 600-pixel template is 1,200 pixels; 2K output is wider than that.
