How to Resize Images for Different Uses

Different platforms need different image sizes. Instagram prefers 1080x1080, YouTube thumbnails work best at 1280x720, and Twitter headers at 1500x500.

Always maintain aspect ratio to avoid stretched images. When reducing size, images stay sharp. When enlarging, expect some softening of fine details.
