Keeping proportions
Set only a width or only a height and the other is worked out for you, so nothing is distorted. Set both and pick letterboxing to keep the shape with padding around it, or turn letterboxing off to stretch the picture into the box.
Sizes worth knowing
- 1200 px wide: a full-width image in a blog post or article.
- 1080 × 1080: a square social post.
- 1200 × 630: the link preview image most platforms crop to.
- Under 500 KB: a reasonable ceiling for anything on a page people load on mobile data.
Common questions
Will enlarging a small image sharpen it?
No. Scaling up spreads the pixels you have over a larger area. It cannot add detail that was never captured.
Why do I end up with white bars?
Letterboxing is on and your target shape does not match the source. Turn it off to stretch, or set only one dimension.
