Resize Image for Instagram

Instagram supports four main image formats, each with a recommended pixel size. Square posts use 1080x1080 pixels. Portrait posts, which take up more vertical space in the feed, use 1080x1350. Stories and reels fill the entire phone screen at 1080x1920. Landscape posts use 1080x566 for wide, cinematic shots.

When you upload an image that does not match these sizes, Instagram resizes it automatically. This often results in unwanted cropping or compression artifacts. By resizing your image before uploading, you control exactly what appears in the frame and ensure the sharpest possible result.

This tool gives you one-click access to all four Instagram presets. Select the format you want, and the tool sets the correct width and height instantly. Your image is processed entirely in your browser, so it stays private and downloads in seconds.

Portrait format (1080x1350) is the most effective size for feed engagement. It occupies more screen real estate than square or landscape, which means users spend more time looking at your content as they scroll. Photographers, brands, and content creators increasingly prefer this format for single-image posts.

Stories at 1080x1920 fill the entire display with no black bars. This is essential for professional-looking stories that feel immersive. If your source image has a different aspect ratio, consider how cropping will affect the composition before resizing.

Landscape format (1080x566) works well for panoramic shots, group photos, and wide product displays. While it takes up less vertical space in the feed, it creates a cinematic feel that stands out from the typical portrait and square posts. For carousel posts, mixing portrait slides with a landscape cover can create visual variety.
