Facebook image compression FAQ
Facebook recommends keeping image files under 4MB. For link preview images, use 1200×630 pixels for optimal display across all device sizes.
Facebook compresses photos automatically. Pre-compressing with ImageSmith at a controlled quality level results in much better final image quality than relying on Facebook's auto-compression.
