When a link is pasted into Facebook, LinkedIn, Slack, WhatsApp or X, the card that appears pulls its picture from the page's Open Graph tag, and the size those platforms agree on is 1200 by 630 pixels, a ratio of 1.91:1. Smaller images get upscaled or shown as a tiny thumbnail beside the title; images of a different shape get cropped from the middle, which is how a headline loses its first and last letters.
This page sets 1200 by 630 as the output with the exact-size option on, so the file you download is precisely what the platforms ask for. That exactness has a side effect worth knowing: because proportions are not preserved, an image that is not already close to 1.91:1 will be stretched to fit. A screenshot or a tall portrait photo will look wrong. Crop to a wide shape first, or design the graphic at that ratio in the first place, and this step becomes a pure pixel-count fix.
The image is resized on your device and never uploaded. Keep any text and logos in the central area, since some apps still trim the edges of the preview on small screens, and keep the file reasonably light; a JPG of 200 to 300 KB is plenty at these dimensions.

Frequently asked questions
- What is an Open Graph image?
- It's the preview image social platforms pull from a webpage when someone shares its link. 1200×630 is the size that displays cleanly across them.
- Why is my link preview cropped?
- Usually because the image isn't 1.91:1. Resizing to 1200×630 matches that ratio so nothing important gets cut off.
- Why 1200 by 630 and not 1200 by 628?
- Both sizes are in circulation because the ratio is roughly 1.91:1 and different platforms rounded it differently. The two-pixel difference is invisible; 1200 by 630 is the figure Facebook's documentation uses, so it is the safer choice.
- Will the new image show up immediately when I share the link?
- Not always. Platforms cache the preview from the first share, so after changing the image you may need their debugging tool, such as Facebook's Sharing Debugger or LinkedIn's Post Inspector, to refresh it.
