Resize Image for Instagram

Get any photo into the right Instagram size in seconds: portrait and square posts, Stories and Reels. Drag to choose the crop, or fit the whole photo on a blurred background so nothing gets cut off.

Instagram tips

  • Portrait 4:5 gets the most screen space in the feed; use it for your strongest images.
  • Your profile grid now shows posts as taller previews, so keep the subject near the centre of portrait posts.
  • For carousels, every slide uses the first slide’s shape, so resize them all to the same size.

Instagram image sizes (October 2026)

These are each platform’s recommended upload sizes, last checked in October 2026. Platforms accept other sizes too, but then crop or scale your image themselves.

Crop or fit?

  • Crop to fill fills the whole frame and cuts off what does not fit. Drag the preview (or use the arrow keys) to choose what stays, and zoom in to frame tighter.
  • Fit whole image keeps the entire photo and fills the gaps with a blurred copy of it or a solid colour. Use it for group photos, screenshots, artwork and anything with text near the edges.

Tick several sizes to download them all at once as a ZIP, for example a square post, a portrait post and a Story from the same photo.

Getting sharp results

  • Start from the largest version of the photo. Enlarging a small image always looks soft; the tool warns you when that happens.
  • Upload at exactly the recommended size, so the platform does not resize it again.
  • Use JPG for photos and PNG for graphics with text. If a platform has a file size limit, use the image compressor afterwards.

Common mistakes

  • Letting the platform crop for you

    Upload a photo in the wrong shape and the app picks the crop, often cutting off heads or text. Crop it yourself first.

  • Text too close to the edges

    Covers and Stories are cropped differently on phones and computers, and app buttons sit over the edges. Keep text and faces near the centre.

  • Resizing an already small image

    A 400-pixel image enlarged to 1080 looks blurry. Find the original photo instead.

Frequently asked questions

What is the best image size for Instagram posts?

1080 × 1350 pixels (4:5 portrait). It takes up the most space in the feed. Square 1080 × 1080 and landscape 1080 × 566 also work, but show smaller.

How do I post a photo on Instagram without cropping?

Choose "Fit whole image". The full photo is placed on a 4:5 or 9:16 canvas with a blurred copy of itself, or a solid colour, filling the gaps, so Instagram has nothing to crop.

What size is an Instagram Story or Reel?

1080 × 1920 pixels (9:16). Keep text and faces away from the top and bottom 250 pixels or so, where the profile name and reply bar sit.

Why does Instagram make my photos blurry?

Instagram scales uploads to 1080 pixels wide and recompresses them. Uploading exactly 1080 pixels wide, in sRGB, avoids an extra resize on their side.

Are my photos uploaded?

No. Resizing runs entirely in your browser. Your photos never leave your device.
