Social platforms use different image placements, and each placement can crop or scale artwork differently. Before exporting, check the current requirements of the platform and the placement you intend to use. These tools offer common pixel canvases, not a guarantee that a platform will never change its specifications.
Choose the placement first
A square feed image, a vertical story and a wide video thumbnail have different shapes. Starting with the correct aspect ratio reduces unexpected cropping.
Fit versus crop
Contain fitting keeps the whole image visible but may leave empty canvas space. Cover fitting fills the canvas but crops some edges. Choose based on whether the entire subject or a full-bleed layout matters more.
Check text and safe areas
Keep important words, logos and faces away from edges where controls or crops may overlap. Preview the result at mobile size.
Use the Social Media Image Resizer, Story Resizer or Thumbnail Maker to build a common canvas size.
