- Recommended
- Full-width images between 600 and 1,000 pixels wide and less than 2,000 pixels high; images narrower than the full width of the email can be smaller than 600 pixels
- Template width
- The default width of every email template is 600 pixels; Klaviyo automatically scales images down to the template width with the aspect ratio preserved
- File size
- Maximum 10 MB per image; 1 MB or smaller is recommended because larger images can load slowly
- Formats
- JPEG, PNG and GIF; a WebP file can be uploaded and converted to PNG, except animated WebP; PSD or SVG files must be converted to a supported type first
- Animated GIFs
- Animated GIFs work in emails as long as they are less than 5 MB; automatic image compression isn't supported for GIFs
- Resolution
- 72 dpi is best practice across the web
- Image quality
- For crisper rendering, insert an image at 2x the desired size and reduce it in the template, for example 600 pixels wide displayed at 300 pixels
- Crop
- Images in image, split and table blocks can be cropped to a circle, a square or a rectangle with a custom width and height; the full image is preserved
- Dark mode
- One option is to use image files that include background colours rather than a transparent background, filling the space completely, for example 600 pixels wide for full-width images
What Klaviyo asks for, covered.
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.
