How to Resize Images for Instagram
Upload your image
Drag and drop any image onto the upload area or click to browse. The tool accepts JPG, PNG, WebP, and GIF files of any resolution and works entirely in your browser.
Select an Instagram preset
Choose from our preset options: Square Post (1080×1080), Portrait (1080×1350), Story or Reels (1080×1920), or Landscape (1080×566). Each preset matches Instagram's recommended dimensions.
Adjust crop or fit
Fine-tune how your image fits within the selected dimensions. You can crop to fill the frame exactly or contain the image within the boundaries to avoid any cutting.
Download your resized image
Click Resize and your image is processed instantly. The output file maintains the original quality at the correct Instagram dimensions, ready to upload directly to your feed or story.
Instagram Image Size Guide
Instagram displays images at specific aspect ratios depending on where they appear in the app. Using the correct dimensions ensures your photos look their best without unexpected cropping or letterboxing. The square 1:1 format (1080×1080) works for standard feed posts and profile grid thumbnails, while portrait 4:5 (1080×1350) takes up more vertical space in the feed and tends to get better engagement. Stories and Reels use a 9:16 vertical format (1080×1920) that fills the entire screen on mobile devices. Even though Instagram applies its own compression to all uploaded images, starting with the exact recommended resolution minimizes additional quality loss and ensures your content displays exactly as intended. Our Instagram image resizer handles all these formats so you can prepare perfect images for every part of the platform.
