Facebook sizes in 2026
Upload 1640 x 624. Desktop shows 851 x 315, phones show a taller crop from the centre, about 640 x 360.
See it before you post
The preview shows your photo inside a mock of Facebook for desktop, mobile, including the areas that get covered or cropped, so you can fix the framing before you upload.
Tip
Keep text and faces in the centre so they survive both the desktop and phone crops.
Resize a whole batch
Drop many photos at once. Each one keeps its own crop position, and you can download them all as a ZIP. Everything runs in your browser, so nothing is uploaded.
