Automatically resize and crop your images for Instagram's recommended dimensions. Choose from feed posts, stories, reels, and profile picture formats.
An Instagram optimizer automatically resizes and crops your images to the exact dimensions recommended by Instagram for posts, stories, reels, and profile pictures. Getting the right dimensions ensures your content looks sharp and professional without unwanted cropping by the platform. Our browser-based tool uses the Canvas API to precisely resize images to Instagram's specifications including square posts (1080x1080), portrait posts (1080x1350), and stories (1080x1920). All processing happens locally in your browser, so your photos stay private and never leave your device.
The recommended size for feed posts is 1080×1350 pixels (portrait, 4:5 ratio). This takes up the most screen space in the feed.
Instagram primarily uses JPEG format. Our tool outputs optimized JPEG at 85% quality, which is the sweet spot between quality and file size.
Yes! After selecting a format and uploading an image, you'll see a preview of how the image will be cropped.
Reels use the same dimensions as Stories: 1080×1920 pixels (9:16 ratio). Select the 'Story / Reel' format.
