High-quality resizing

Fast, simple, and made for your device

This wide 851 × 315 canvas matches the classic Facebook cover photo shape. Keep important subjects near the center because different devices can crop cover photos differently. The tool automatically center-crops to the required aspect ratio and resizes to exactly 851 × 315 pixels. Review the thumbnail before downloading, especially when the original has a very different shape.
