How it works

Three steps, no learning curve

01

Find your format

Pick the network and placement — feed, story, Reel, cover or profile.

02

Use the exact dimensions

Export at the listed size so nothing is cropped or softened on upload.

03

Let the product size it

In Social Media Digital Marketer, one asset is resized per channel automatically, with safe zones respected.

Tips

Get more out of it

  • Design vertical first — 4:5 and 9:16 take up more screen than square or landscape.
  • Keep text and logos inside the safe zone so stickers and UI never cover them.
  • Upload at the exact dimensions; letting the platform resize is where quality quietly disappears.
