Resize an image for Facebook square post: 1080 × 1080 px
Drop a photo and get it at exactly 1080 × 1080 pixels, the Facebook square post size (1:1 ratio). The image is scaled to fill the frame and centre-cropped, so nothing is stretched. Performs well on mobile where the feed is narrow.
How to use the Facebook square post resizer
- Add one or more photos (JPG, PNG, WebP or iPhone HEIC).
- The size is preset to 1080 × 1080; adjust only if Facebook changes its spec.
- Click Resize. The photo is scaled to cover the frame and cropped from the centre.
- Download and upload to Facebook.
Facebook square post size in 2026
The recommended Facebook square post image is 1080 × 1080 px, an aspect ratio of 1:1. Performs well on mobile where the feed is narrow. Facebook compresses images heavily. Uploading at its stated sizes, as JPG under 1 MB, produces less visible compression than larger files, because the platform then skips a resize pass. Cover photos are cropped differently on desktop and mobile, so keep the subject in the centre.
How this tool fits your photo
Most photos are 4:3 or 3:2, not 1:1. Rather than stretching, this tool scales the photo until it covers the 1080 × 1080 frame and then crops equally from the edges that overflow. For a portrait photo going into a landscape slot, that means the top and bottom are trimmed; for a landscape photo going into a portrait slot, the sides. If the subject is off-centre, crop it roughly first in your phone's editor, then use this tool for the exact pixels. Images smaller than 1080 × 1080 are enlarged, which softens them slightly; start from the largest original you have.
Format and file size
JPG for photos, PNG for graphics with text (less compression on text edges). 15 MB per image (JPG); under 1 MB recommended. Output here keeps your input format (JPG stays JPG at quality 90, PNG stays PNG). If the result is over the platform's limit, run it through the image compressor with a target size.
