Step-by-step guide to resize image for instagram:
Determine your Instagram image type
Feed post (square): 1080×1080px. Feed post (portrait, best for engagement): 1080×1350px. Feed post (landscape): 1080×566px. Stories and Reels: 1080×1920px. Profile picture: 320×320px.
Upload your image to FixTools
Open the Image Resizer and upload the image you want to prepare for Instagram.
Enter Instagram dimensions
Type in the width and height for your chosen Instagram format. For example, enter 1080 × 1350 for a portrait feed post.
Crop if needed
If the aspect ratio of your original image is different from the Instagram format, use the Image Cropper first to crop to the correct ratio, then resize.
Download and upload to Instagram
Download your resized image and upload it directly to Instagram. Your image will match the platform's native resolution.
