Instagram Image Resizer

How to resize an image for Instagram

1. Choose, drop or paste a photo. JPG, PNG, WebP and iPhone HEIC photos all work.
2. Pick the Instagram size: a feed post shape, a Story or a Reel cover. Each shows its pixel size and ratio.
3. Decide what happens when the shapes differ. Crop to fill lets you drag the frame to the part you want; Fit whole photo keeps everything and adds a background.
4. Choose JPG, PNG or WebP and the quality, then select Create Instagram image.
5. Compare the original and the result, including the new dimensions and file size, and download.

Choosing the right Instagram size

Feed posts

Feed posts can be square, portrait or landscape. A 4:5 portrait (1080 × 1350) is usually the best pick for photos of people, products and food, because it takes up the most room as people scroll. Use the square preset when a consistent grid matters, and landscape for scenery and group shots. The 3:4 preset matches the taller previews on profile grids, but older apps and some publishing tools may still trim it to 4:5, so check it after posting.

Stories and Reels

Stories and Reels fill the screen with a 9:16 vertical frame of 1080 × 1920. They follow different rules from feed posts: buttons, captions and your profile name are drawn over the picture, and a Reel cover appears in your profile grid as a cropped middle section. Turn on the guide to see which areas to keep clear.

Instagram image size reference

These are the sizes most creators use. Instagram re-compresses every upload and can change how it displays each format, so treat them as reliable starting points rather than fixed rules. Feed images wider than 1080 pixels are scaled down when posted, so there is little benefit in uploading larger files.

Crop or fit: which should you use?

Cropping fills the whole frame with your photo and cuts off whatever falls outside it. It looks cleanest in the feed, and you choose exactly which part stays by dragging the frame, zooming with a pinch or Ctrl + scroll, or using the arrow keys.

Fitting keeps every pixel of the photo and fills the empty space instead. A white or black background gives a gallery look, a blurred copy of the photo looks seamless, and a border adds the same margin on every side. Use it to resize a photo for Instagram without cropping a panorama, a screenshot or a group shot where no one should be cut out. The image is never stretched in either mode.

Tips for sharp results and no surprise cropping

• Start from the original photo, not a screenshot or a copy saved from a messaging app, which are often reduced.
• If the tool says your photo will be enlarged, choose a larger crop area or a higher-resolution original. A blurry-looking upload is usually an enlarged one.
• Keep text and faces away from the edges of Stories and inside the grid area of Reel covers.
• Save as JPG at around 90% quality. If you need a smaller file afterwards, the image compressor shrinks it without changing the dimensions.
• Got an iPhone photo in HEIC format, or a WebP saved from a website? They open here directly, or you can convert them first with HEIC to JPG and WebP to JPG.

Other sizes and formats

For any other dimensions, use the general image resizer, which resizes by pixels or percentage. To crop freely or to ratios such as 16:9 for other sites, use the image cropper. Need a lossless copy for editing or a transparent background? Convert JPG to PNG.
