About this Tool

Instagram Post Resizer

The Instagram Post Resizer is a free online tool that helps you resize images for Instagram posts quickly and easily. Upload your photo, choose the format you need, and create an image optimized for sharing on Instagram.

Whether you need a square, portrait, or landscape image, this tool makes it easier to prepare your photos for Instagram without complicated image-editing software.

Quick Tip: Choose the image format that best matches your content. Portrait images can occupy more vertical space in the Instagram feed, while square and landscape formats can be useful for different types of content.

Instagram Post Sizes

Instagram supports several image orientations for feed posts. Common dimensions include:

  • Square: 1080 × 1080 pixels
  • Portrait: 1080 × 1350 pixels
  • Landscape: 1080 × 566 pixels

Using an appropriate aspect ratio helps your image fit the Instagram feed correctly and reduces the need for unwanted cropping.

How to Resize an Image for Instagram

  2. Select the desired Instagram post format.
  3. Choose square, portrait, or landscape dimensions.
  4. Adjust the image position if necessary.
  5. Preview the resized image.
  6. Download your optimized image.

Why Resize Images for Instagram?

Photos taken with phones and cameras can have many different dimensions and aspect ratios. Resizing an image before uploading can help you control how the photo appears in your Instagram feed.

  • Prepare photos for Instagram feed posts.
  • Reduce unwanted cropping.
  • Choose the correct image orientation.
  • Create consistent-looking social media content.
  • Prepare images quickly without professional software.
  • Optimize images for common Instagram dimensions.

Square Instagram Posts

Square images use a 1:1 aspect ratio and have traditionally been one of the most recognizable Instagram post formats. A common working size is 1080 × 1080 pixels.

Portrait Instagram Posts

Portrait posts use a taller aspect ratio and can take up more vertical space while users scroll through their feeds. A common size is 1080 × 1350 pixels.

Landscape Instagram Posts

Landscape images are wider than they are tall. A commonly used size is 1080 × 566 pixels. This format can work well for panoramic photographs, landscapes, and wide designs.

Resize vs. Crop

Resizing changes the dimensions of an image, while cropping removes parts of the image to achieve a particular aspect ratio. Depending on the original photo, preparing an image for Instagram may require resizing, cropping, or both.

Best Practice: Keep important faces, text, logos, and other key elements away from the edges of the image so they are less likely to be affected by cropping.
