How to Resize an Image for Instagram in 3 Easy Steps

Follow these three simple steps to resize an image for Instagram. No software installation required. Free and secure.

    Select one JPG, JPEG, PNG, WebP, AVIF, or BMP image from your device, or drag and drop it into the browser.

    Choose an Instagram Preset

How Does the Instagram Image Resizer Work?

The CompressFly Instagram image resizer creates an image at the exact dimensions of the selected 3:4 portrait, 4:5 portrait, square, landscape, Story or Reel, or profile preset. Crop to Fill covers the target canvas and lets you reposition or zoom the source. Fit Entire Image keeps the complete source visible and fills unused canvas space with the selected background color.

The Story or Reel preset shows a suggested safe-area guide, and the profile preset shows a circular display guide. These guides are not included in the downloaded JPG or PNG. Resizing and export are completed directly in your browser.

What "in your browser" means

  • No Instagram image is uploaded to a server
  • Resizing, cropping, and export are processed locally on your device
  • The finished JPG or PNG is downloaded directly from your browser

Instagram Image Resizer FAQ

How do I resize an image for Instagram?

Resize an image in three steps: 1. Add one supported image. 2. Choose an Instagram placement preset and adjust the crop or fit. 3. Select JPG or PNG and download the image at the displayed dimensions.

Which Instagram image sizes are included?

The tool includes 1080 × 1440 and 1080 × 1350 portrait posts, a 1080 × 1080 square post, a 1080 × 566 landscape post, a 1080 × 1920 Story or Reel image, and a 1080 × 1080 profile picture.

Should I use 3:4 or 4:5 for an Instagram portrait?

Choose 3:4 when you want the 1080 × 1440 portrait preset. Choose 4:5 for the widely used 1080 × 1350 portrait shape. The correct choice depends on the placement and framing you need.

Will the Instagram profile download be circular?

No. The profile preset exports a square JPG or PNG. The circular overlay is only a display guide.

Is the Story or Reel safe-area guide included in the image?

No. It appears only in the editor to help position important content and is not part of the downloaded file.

Are my Instagram images uploaded to a server?

No. Resizing and export run locally in your browser, so the image is not uploaded to a server.
