How to shrink an image without losing quality
Kapwing's image shrinker lets you resize photos without affecting image quality. Create a new project in the Kapwing studio, then click to upload your image. Click "Resize Project" in the righthand toolbar, then choose from presets for everything from YouTube thumbnails (16:9) to LinkedIn or Instagram squares (1:1).
