Free Instagram post resizer

Resize a photo to the sizes Instagram uses for feed posts and for Stories and Reels, right in your browser. Load a photo, choose a format, decide whether the photo should fill the frame or fit inside it, position it and download the result.

Instagram image sizes

  • Square: 1080 x 1080 pixels (1:1).
  • Portrait: 1080 x 1350 pixels (4:5), which takes up the most room in the feed.
  • Landscape: 1080 x 566 pixels (1.91:1).
  • Story / Reel: 1080 x 1920 pixels (9:16).

How to resize a photo for Instagram

  1. Load a JPG, PNG or WebP image.
  2. Choose the format: Square, Portrait, Landscape or Story / Reel.
  3. Pick a fit mode. Fill and crop covers the whole frame and trims the edges; drag the photo and use the zoom slider to choose what stays in view. Fit and pad keeps the whole photo and fills the extra space with a colour you choose.
  4. Choose JPEG for a smaller file or PNG for lossless quality, then export the image.

Frequently asked questions

Yes. It is free to use and needs no sign-up.

No. The resizing happens in your browser, so your photo is not uploaded to a server.

Portrait (1080 x 1350) uses the most space in the feed, square (1080 x 1080) is the classic choice, and landscape (1080 x 566) suits wide photos. Pick the one that shows your photo best.

Fill and crop fills the whole frame and cuts off whatever sticks out, and you can drag and zoom to choose what stays. Fit and pad keeps the whole photo and fills the leftover space with a colour you pick.

Choose Story / Reel, which is 1080 x 1920 pixels (9:16). To add text to a Reel cover, use the Reel Cover Maker.

A photo that is smaller than the size you choose has to be enlarged, which can look soft. For the sharpest result, start with a photo that is at least as big as the size you pick.
