Facebook Post Resizer
Portrait posts fill more of the screen as people scroll Facebook on their phones. This page resizes your photo to 1080×1350, the 4:5 shape that stands out in the feed. Everything runs in your browser — nothing is uploaded. Need a smaller file instead? Compress or convert.
Drag the preview to choose which part of the image is kept. The same framing is used for every image in the batch.
Getting the Facebook post right
Facebook accepts many shapes for a photo post, but on a phone the tall 4:5 portrait gets the most room in the feed — the reason so many brands use it.
Tallest feed image
4:5 fills more of a phone screen than square or landscape posts.
Fits phone photos
A 3:4 phone photo only loses a thin strip top and bottom.
Same as Instagram portrait
One 1080×1350 image works for both Facebook and Instagram.
Sharp after compression
1080 px wide matches what Facebook keeps for the feed.
About 230 KB–460 KB as JPG
A typical photo at 1080×1350 saves to roughly 230 KB–460 KB at good quality — well within the upload limit.
You choose the crop
Filling 1080×1350 from a 3:4 phone photo trims about 6% of it. Drag the preview to choose what stays, or tick the fit option to keep everything.

Why portrait wins in the feed
More screen, more attention. Most Facebook browsing happens on phones, where a 4:5 portrait image is noticeably taller than a square or landscape one. That extra height keeps your post on screen for longer as people scroll.
From a phone photo. A normal phone photo is 3:4, very close to 4:5, so only a thin strip is trimmed from the top and bottom. Landscape photos lose much more — for those, a square post may be the better choice.
Several photos? When a post has multiple images Facebook arranges them in a grid and crops them; keeping them all the same size gives the tidiest layout.

Frequently asked questions
What is the best size for a Facebook post image?
1080×1350 pixels (4:5 portrait) takes up the most space in the mobile feed. Square 1080×1080 and landscape 1200×630 also work.
Does Facebook crop 4:5 photos?
No, 4:5 is shown in full in the feed. Taller images (such as 9:16) are cut down in the feed preview, which is why 4:5 is the safe maximum.
Should Facebook posts be square or portrait?
Portrait (4:5) takes more space on phones; square is a safe middle ground that also looks good on computers. Both are much better than very wide images.
Can I use the same image on Instagram?
Yes — 1080×1350 is also Instagram’s portrait size. See the Instagram portrait resizer.
Are my images uploaded?
No. Resizing happens entirely in your browser. Nothing is transmitted or stored, and you can disconnect from the internet after the page loads and it still works.
