An Instagram feed crop is a small, kind decision. Lock the square or the taller portrait, keep the subject inside that frame, and download a photo that already matches the post you have in mind. The square preset is 1:1, labeled for an Instagram post. The portrait preset is 4:5, labeled for an Instagram portrait. Both live on the same crop as freeform, 16:9, and a Facebook frame at 1.91:1. This page stays with the two feed shapes. You open a JPG, PNG, or WebP, click the preset, and drag until the face, the dish, or the product sits where the post should hold it. While you drag, the page shows the selection size in pixels. That readout is useful even when the ratio is locked, because it tells you how much of the original you are keeping. A large camera file gives you room to scale the 1:1 box generously. A small screenshot may already be tight. Look at the corners. Hats, hands, and captions are the details people notice after the post is live. JPEG and WebP export at quality 0.92. A PNG export stays a PNG. The format follows the file you opened, and the session stays on your device. Download, then upload that picture in the Instagram app. The crop prepares the still. It does not publish it. If you are choosing between the two feed presets, use the square when the image should match a grid of other squares, and use 4:5 when this one post should occupy more of the phone screen. Either way, the subject should be a decision you made with the box, not a guess you leave to the app.

Two feed presets, placed by hand

1:1 and 4:5 are the Instagram shapes on this crop. Lock one, move it, and the pixel readout confirms how large the kept region is. The other presets remain on the tool for different jobs, and a feed post is clearest when you start from the feed shape itself.

How it works

  1. 1

    Open a JPG, PNG, or WebP

    The crop runs in the browser. A phone photo that is still HEIC should be converted to one of those three types first.

  2. 2

    Lock 1:1 or 4:5

    Choose the square for a grid tile or the portrait for a taller feed post. Drag the frame until the subject is comfortable inside it.

  3. 3

    Read the pixels and save

    The selection size is printed in pixels. JPEG and WebP download at quality 0.92. Then upload that file in the app.

Use cases

A grid tile

Lock 1:1, keep the subject centered, and save a square you can drop among the other square posts.

A taller single photo

Lock 4:5 so the post uses more vertical space, with the face or product fully inside the frame.

A second pass after a surprise crop

If the app trimmed something you needed, return to the original, place the preset again, and export a more generous window.

Problems we solve

A landscape forced into a tall post

4:5 will drop the sides. Slide the window so the subject, not the empty background, is what remains.

Important detail on the edge

Leave a margin inside the preset. The pixel readout helps you see that the box still has room around the subject.

Uploading the uncropped original

The app will choose a center if you skip this step. Place the 1:1 or 4:5 box yourself and upload the result.

Trust, speed & privacy

Feed ratios that are actually on the page

The square preset is 1:1 and the portrait preset is 4:5. You can see which one is active before you download.

Framed locally

The photo stays on your device while you drag. JPEG and WebP export at quality 0.92.
