Resize Image for Instagram — All 2025 Dimensions

Instagram compresses and crops photos that don't match its preferred dimensions — cutting off faces, stretching graphics, or adding unwanted white bars. Resize your image to the exact pixel dimensions Instagram uses before you post, and it will always display perfectly.

How It Works

  1. 1

    Upload your photo

    Drop a JPG or PNG into the tool. Instagram supports both formats, but JPEG gives smaller file sizes for photos.

  2. 2

    Set Instagram dimensions

    Square post: 1080×1080 px. Portrait post: 1080×1350 px. Landscape post: 1080×566 px. Instagram Story/Reel: 1080×1920 px.

  3. 3

    Download and post

    Save the resized image and upload it directly to Instagram. No resizing or cropping will occur on Instagram's end.

Frequently Asked Questions

What is the best image size for an Instagram post?+
The universally safe size is 1080×1080 px (1:1 square). For portrait posts, 1080×1350 px gives maximum screen real estate in the feed. Use 1080×1920 px for Stories and Reels.
Why does Instagram make my photo blurry?+
Instagram re-compresses images that exceed 1MB or are not the correct aspect ratio. Always upload at 1080px width and under 1MB. Our compressor can reduce the file size after resizing.
Does cropping happen automatically when I resize?+
Only if you change the aspect ratio. Use "Lock aspect ratio" when resizing to keep the full image and manually crop afterward if needed using the Crop Image tool.
