# HEIC to 1080 × 1080 > Resize HEIC to 1080x1080 squares for Instagram posts and marketplace thumbnails. Centre-crops to fill the square without stretching. Free and in-browser. URL: https://ihateheic.com/resize-heic-to-1080x1080 Updated: 2026-10-04 Turn iPhone photos into perfect 1080 × 1080 squares for Instagram grids and shop thumbnails. Every photo is centre-cropped to fill the square, so nothing gets squashed. This tool runs entirely in the browser: photos are decoded and encoded on the visitor’s device and are never uploaded. It is free, needs no sign-up and works offline after the first visit. ## How to use it 1. Drop your HEIC photos above. Portrait and landscape both work. 2. Each photo is scaled and **centre-cropped** to exactly **1080 × 1080** pixels. 3. Download the squares, or save them to Photos on iPhone, and post. ## The square that never goes out of style Instagram made 1080 × 1080 famous, and it stuck. The square shows up all over the place: - **Instagram feed posts** and grid previews - **Marketplace and shop thumbnails**, where a grid of equal tiles looks professional - **Profile pictures and podcast covers** that are displayed square - **Catalogue sheets** and printed contact sheets Your iPhone shoots 4:3 by default, so every photo needs trimming to become square. ## Fill vs fit, in plain English There are two ways to get a rectangle into a square box. - **Fit** shrinks the photo until all of it fits, then leaves empty bars at the sides or top and bottom. You keep the whole photo but get a letterbox. - **Fill** shrinks the photo until it *covers* the box, then trims what spills over. No bars, a little lost at the edges. This page uses **fill with a centre crop**. That's what social apps expect: a clean, edge-to-edge square. | Your photo | What gets trimmed | | --- | --- | | Portrait (3:4) | Top and bottom | | Landscape (4:3) | Left and right | | Already square | Nothing, just resized | ## When the centre isn't the point Centre-cropping is right for most photos, but not for a friend standing at the edge of the frame. For those, open [Crop HEIC](https://ihateheic.com/crop-heic), pick the 1:1 preset, and drag the box onto your subject. Then bring the result back here to resize it to exactly 1080 px. Fixing a photo that's lying on its side? Do that first with [Rotate HEIC](https://ihateheic.com/rotate-heic), otherwise the crop happens on the wrong axis. ## Shop thumbnails in one batch Drop a whole folder of product photos and you get a matching set of squares, all the same size, ready for a listing grid. Quality is set to 90, which keeps product detail sharp while files stay small. If your marketplace has a size cap, chain this with [compress to 500 KB](https://ihateheic.com/compress-heic-to-500kb). ## Straight from your phone On iPhone, choose photos from your library, let them process, then tap **Save** to put the squares back in Photos, ready for the Instagram app. It all happens in Safari, with nothing uploaded on the way. ## FAQ ### What size is an Instagram square post? 1080 × 1080 pixels is the standard size for a square post. Upload at exactly that size and the app has less reason to resize or recompress your photo further. ### Will my photo be stretched to make it square? No. We scale the photo until it covers the square, then trim the edges that stick out. Proportions are never distorted. ### Which part of the photo is kept? The centre. For a portrait photo the top and bottom are trimmed; for a landscape photo, the sides. If your subject is off-centre, use Crop HEIC with the 1:1 preset to choose the framing yourself. ### Can I make square images for a shop or marketplace? Yes. Square thumbnails make a product grid look tidy. Drop all your product photos in and download them as one ZIP. ### My photo is smaller than 1080 pixels. What happens? Resizing can't add detail that isn't there. For the sharpest squares, start from a photo at least 1080 pixels on its short side, which every iPhone photo is. ### Should I choose JPG or PNG? JPG for photos. It's much smaller and every social app accepts it. PNG makes sense only for graphics with text or flat colour.
