What aspect ratio is 1080 × 1350?

It is 4:5, or 0.8 when written as width divided by height. For many years it was the tallest ratio Instagram’s feed allowed.

Can I resize several slides for a carousel?

Process them one after another: drop a slide, download it, then drop the next. Every output has identical dimensions, which carousels require.

Is the output a JPG or a PNG?

It follows your input. A PNG graphic stays PNG so text edges remain sharp; a JPG photo stays JPG. HEIC photos are saved as JPG.

Resize Image to 1080x1350 Pixels (4:5)

1080 × 1350 pixels is the classic 4:5 portrait format for social feeds. It takes up more of the screen than a square while still being shown uncropped in Instagram and Facebook timelines, which is why designers build carousels and announcement graphics at this size.

Add a picture and this page returns it at exactly 1080 × 1350, filling the frame and trimming the edges evenly.

Before and after

An open blank notebook with glasses, a pen and a cup of coffee on a grey concrete surface — The dashed frame on the left marks the part that fits the new shape. It was scaled to exactly 1080 × 1350 px, and the top and bottom outside the frame were trimmed.

Confirm the framing in the preview and download.

What gets trimmed

A 4:5 frame is a little squatter than a phone’s native 3:4 photo, so a vertical phone shot loses about three percent from the top and three percent from the bottom. A square image loses a tenth from each side. Landscape photos lose far more, about 40 percent of the width for a 4:3 shot and over half for 16:9; for those, consider posting in a wider format instead.

Designing for the 4:5 frame

When preparing graphics with text, keep titles and logos inside the central 1080 × 1080 area. Grid thumbnails and link previews often show only the middle of a post, and anything near the top or bottom edge can be hidden. Exporting at exactly 1080 pixels wide also avoids a second round of scaling by the platform, which keeps fine lettering crisp.
