Every platform crops for you if you do not crop first

Upload a 16:9 photo to Instagram's feed and it is cropped to 4:5. Upload a 4:5 image as a LinkedIn banner and it is cropped to 4:1. The platform picks the centre, which is almost never where your subject is. Cropping deliberately, before upload, is the only way to control what survives.

The ratios worth memorising: 1:1 for profile images everywhere; 4:5 for the tallest image Instagram will show in-feed; 16:9 for YouTube thumbnails, presentation slides and most video; 1.91:1 for the Open Graph preview that appears when your page is shared on Facebook, LinkedIn or Slack.

That last one is the most consequential and least known. Get the Open Graph ratio wrong and every share of your page shows a badly cropped preview, which measurably depresses click-through.

Frequently asked questions

What aspect ratio should I use for a social media post?
1:1 for profile pictures, 4:5 for the tallest in-feed Instagram post, 16:9 for video thumbnails and slides, and 1.91:1 for the link preview image that appears when a page is shared.
Does cropping reduce image quality?
No. Cropping discards pixels outside the selection and keeps the rest untouched. The output is saved as PNG, which is lossless.
Can I crop to an exact pixel size?
Crop to the correct ratio here, then use Resize Image to hit an exact pixel dimension. Doing it in that order avoids distorting the image.
Why does the crop box snap when I pick a ratio?
Because the height is calculated from the width to maintain the ratio. Drag horizontally to size the box; the height follows.
Is the cropped area really removed?
Yes. The output image contains only the selected pixels. Unlike some PDF crops, nothing is merely hidden.
