Resize an image to 1080×1080 pixels

To resize an image to 1080×1080 px, enter 1080 × 1080 px and pick crop to fill so the 1:1 frame is not stretched: a 4:3 phone photo loses 25% of its area (a centred 3024×3024 crop). The result has 1.17 megapixels; as a JPEG, a detailed outdoor photo is about 395 KB at the panel's default quality 85 (300 KB at quality 75).

What 1080×1080 means in pixels

1080×1080 is a square, 1080 pixels on each side, 1,166,400 pixels in total (1.17 megapixels). Its sides reduce to 1:1 (1 as a decimal), so any picture cropped to 1:1 scales to it without distortion.

A 12 MP phone photo has 10 times as many pixels, so reaching 1080×1080 is a clean reduction with no invented detail. Shown 1:1 it fills 1080×1080 CSS px on a standard screen and 540×540 CSS px on a 2× (Retina-class) screen; at 72 DPI the same pixels span 15×15 inches.

Decoded for editing it occupies 4.45 MB of memory (4 bytes per pixel); uncompressed 24-bit RGB would be 3.34 MB, which is why the downloadable JPEG, PNG or WebP is far smaller.

Getting 1080×1080 from a phone, camera or screenshot

Filling 1080×1080 from a 12 MP phone photo (4032×3024, 4:3) loses the least (25%); a vertical phone video frame (1080×1920, 9:16) loses the most (43.8%). "Fit inside" keeps the whole picture instead and the file comes out at the size in the last column; "Pad with colour" adds bars to reach the full 1080×1080. From the phone photo PixelFit takes the 3024×3024 crop through 1512×1512 before the last step to 1080×1080, so each pass blends neighbouring pixels instead of skipping them.

How many KB is a 1080×1080 image?

Estimated from encodes of real sample images measured with sharp 0.35.5 / libvips 8.18.7 on 31 October 2026, interpolated to 1,166,400 pixels. The outdoor photo at 1080×1080 is about 300 KB at quality 75 and a scanned page about 156 KB; your file will differ with detail and noise.

How to resize a picture to 1080×1080

  1. Add the picture

    Drop, paste or pick the photo in the PixelFit panel at the top of this page; it is decoded in your browser and never uploaded.

  2. Set the size

    Enter 1080 as the width and 1080 as the height in pixels (the panel is already set to 1080×1080).

  3. Choose how it fits

    Choose crop to fill to keep the 1:1 frame without stretching (a phone photo loses 25%, left and right cut). Fit inside keeps the whole picture as a 1080×810 file instead; Pad with colour puts that on a full 1080×1080 canvas.

  4. Pick the format and download

    Choose JPG or WebP; without a KB limit PixelFit saves JPG at quality 85, about 395 KB for a detailed outdoor photo. Add a KB limit if the upload has one or the file should be smaller, then download the 1080x1080 file.

Frequently asked questions

How do I resize an image to 1080x1080?

Open the image in the PixelFit panel on this page, set 1080 × 1080 px, choose crop to fill so nothing is stretched and download. From a 12 MP phone photo that crops 25% (left and right cut) and scales the rest by 0.357×.

What aspect ratio is 1080x1080?

1080x1080 has an aspect ratio of 1:1: square, width ÷ height = 1. Sizes with the same ratio include 1024×1024 square, 1000×1000 square and 1200×1200 square.

Is 1080x1080 good for print?

At 300 DPI 1080x1080 prints 3.6×3.6 in (9.1×9.1 cm). At 150 DPI it stretches to 7.2×7.2 in.

How big is a 1080x1080 JPEG file?

For a detailed outdoor photo about 300 KB at quality 75 (226 KB at 60, 480 KB at 90, 395 KB at the panel's default quality 85); a head-and-shoulders portrait is about 112 KB at quality 75, estimated from measured encodes. A flat graphic is smaller, a noisy low-light photo larger.

How does 1080x1080 look on a high-density screen?

On a 2× screen 1080x1080 is sharp when shown at 540×540 CSS px; shown larger, the browser enlarges it. A slot of 1080×1080 CSS px on a 2× screen needs a 2160×2160 file.
