Social platforms often expect specific widths and heights. Uploading an image that is too large or the wrong shape can trigger awkward crops.
Open the image resizer, enter the target width and height, and decide whether to keep the original aspect ratio. Keeping the ratio prevents stretching.
If the platform needs a fixed frame, resize first and then review the composition. Important subjects should stay near the center when possible.
Export a copy for each channel you publish to. A story size and a feed size are rarely interchangeable.
Before posting, open the resized file once more and confirm that text and logos remain legible on a phone screen.
