Resize an older 820×312 cover
Create an exact 820×312 image for a legacy Facebook cover template or an archived design system that still specifies this canvas. The page remains available so existing assets do not need to change dimensions unexpectedly.
For new Page covers, use the 851×315 variant. Facebook currently lists 851×315 as its fast-loading cover-photo size.
Legacy template behavior
The resizer fills the frame with a centered cover crop. A source with a different ratio loses content from its longer dimension instead of being stretched.
Facebook can apply another crop after upload. Keep important text and logos near the center even when the artwork matches the older pixel dimensions.
Preserve archived batches
Process several old campaign files together and export the results as a ZIP. The resize step preserves source format but does not reproduce Facebook’s final device-specific display crop.
