How to resize a photo for Instagram

  1. Add your photos. Drop JPG, PNG, WebP or iPhone HEIC photos into the box, paste one with Ctrl+V, or browse. Up to 30 at once.
  2. Pick the Instagram format. Square, Portrait 4:5, Grid 3:4, Story or Reel 9:16, Landscape, Profile picture - or Carousel to split a panorama.
  3. Choose crop or fit. Crop fills the frame - drag the photo and zoom to frame it. Blur fit and Colour fit keep the whole photo with no cropping.
  4. Download. Check the real file size and press Download. Three or more files come as one ZIP.

These are the recommended sizes as of 2026. Instagram changes them now and then, so the tool is updated when it does.

Posting the same photo to Facebook, X or Pinterest too? The Social Media Image Resizer makes every size in one go.

Seamless panorama carousels

A carousel of 2 to 10 slides lets one wide photo scroll sideways like a panorama.

The tool scales your photo to the full width of all slides and cuts it at exact pixel boundaries, so the edges of neighbouring slides match. Drag up or down to choose which band of the photo is used.

  • Pick 4:5 slides for the tallest look in the feed.
  • Upload in order - files are named slide-01, slide-02 and so on.
  • Need more width? A soft result means the photo is smaller than the slides - sharpen it first with the Image Upscaler.

Tips for sharper Instagram photos

  • Upload exactly 1080 px wide. Bigger files are shrunk by Instagram anyway, often less carefully.
  • Use Blur fit for group photos so nobody at the edge gets cut off.
  • Check the grid. Grid preview shows what the 3:4 profile tiles hide, so faces and text stay visible.
  • Protect your work with a small logo from the Watermark Maker.

Frequently Asked Questions

For the feed, 1080 x 1350 (4:5 portrait) takes up the most screen space. Square posts are 1080 x 1080, the newer 3:4 grid shape is 1080 x 1440 and landscape posts are 1080 x 566.

Stories and Reels use 1080 x 1920 (9:16).

Choose a fit mode instead of Crop. Blur fit places the whole photo on a soft blurred copy of itself, Colour fit places it on white, black or any colour you pick.

Add a border for a clean gallery frame.

Choose Carousel, pick the slide shape (1:1, 4:5 or 3:4) and the number of slides from 2 to 10. The tool cuts your wide photo into slides that line up perfectly, so it scrolls as one seamless picture.

Post the slides in order - the file names are numbered for you.

The profile grid shows posts as 3:4 tiles, so square and landscape posts lose their sides there and 4:5 posts lose a thin strip.

Turn on Grid preview to see exactly what the grid will hide before you post.

Yes. Instagram re-compresses every upload and shrinks anything wider than 1080 pixels.

Uploading exactly 1080 pixels wide as a high quality JPG gives Instagram the least to change, which keeps photos sharper. The real file size is shown before you download.

Yes. HEIC photos are converted in your browser, and you can add up to 30 photos at once. Each photo keeps its own crop position and zoom.

More than two files download together as one ZIP. For other formats, see HEIC to JPG.

No. Resizing happens entirely in your browser, so your photos never leave your device. There is no watermark and no sign-up.
