Why the right size matters
Instagram fits every photo to its own sizes. If you resize first, you choose the crop, not Instagram.
Instagram crops what doesn't fit
A photo that is not one of Instagram's shapes gets cropped when you post it, and the crop can cut off a face, a product or a line of text. A photo much bigger than Instagram needs gets compressed hard, which is why some posts look soft or blotchy. Resize to the exact size first, and you keep control of the framing and the sharpness.
Which size to pick
For feed posts, portrait 4:5 (1080 × 1350) is usually best, because it fills the most of the screen as people scroll. Tall portrait 3:4 (1080 × 1440) matches the 3:4 tiles on your profile grid exactly. Square 1:1 is the safe choice for a mix of photos. Landscape 1.91:1 suits wide scenes, but it is the smallest in the feed. Stories and Reels fill the screen at 9:16. A profile picture shows as a small circle, so keep the subject in the middle. To see how posts look side by side, try the Instagram feed planner.
Tips for sharp photos
Start from the largest copy of the photo you have. Keep the width at 1080 pixels so Instagram doesn't have to stretch it. Download photos as JPG, which gives smaller files that upload faster, and graphics with text or sharp edges as PNG. In a Story, keep text and stickers away from the top and bottom, where Instagram puts your name and the reply bar. When the photo is ready, post it, or schedule it with Posttyy's Instagram scheduler so it goes out when your followers are online.
Questions, answered
How do I resize a photo for Instagram?
Drop your photo into the resizer and pick the Instagram size you need. Drag the crop box to frame the shot, then download. The photo comes out at the exact size Instagram shows, so nothing gets cropped or squashed when you post it.
What size should an Instagram post be?
A portrait post is 1080 × 1350 pixels (4:5). A square post is 1080 × 1080 (1:1). A landscape post is 1080 × 566 (1.91:1). Portrait takes up the most space in the feed, so most brands use it.
What size are Instagram Stories and Reels?
Stories and Reels are full screen: 1080 × 1920 pixels (9:16). Keep text and faces away from the top and bottom edges, where Instagram shows your name and the reply bar.
What size is an Instagram profile picture?
Instagram keeps profile pictures at 320 × 320 pixels and shows them as a circle. The resizer draws that circle inside the crop box, so you can see what will be cut off.
Why are my posts 3:4 on my profile grid?
Instagram's profile grid shows every post as a 3:4 rectangle, cut from the centre. In the feed, the post still shows at its full shape. Instagram also takes 3:4 photos at 1080 × 1440, which fill a grid tile exactly.
Does resizing make my photo worse?
No, not if you start from a sharp photo. It usually makes the post look better, because Instagram compresses an oversized photo much harder. The resizer never stretches a photo: if your crop is smaller than the size you picked, it downloads at its real size and tells you so.
Should I download a JPG or a PNG?
Use JPG for photos. The files are smaller, upload faster and look the same in the feed. Use PNG for graphics, screenshots and anything with text or sharp edges, where JPG can leave blurry marks.
Is the Instagram photo resizer free?
Yes. It is free, with no account, no watermark and no limit on downloads.
Are my photos uploaded?
No. The resizer works in your browser, so your photo never leaves your computer. That also makes it fast: there is no upload to wait for.
