What is Resize images for Facebook?
TL;DR: Shrink44 resizes images to Facebook's ideal dimensions (1200×630 link posts and 1080×1080 square posts) in your browser, so your uploads stay sharp and correctly framed.
Facebook downscales and crops images that don't match its preferred sizes. Pre-sizing to the recommended 1200×630 link posts and 1080×1080 square posts keeps your images crisp and framed how you intend.
Shrink44 lets you enter exact dimensions or pick from built-in presets, with contain / cover / stretch fit modes — all locally, no uploads.
