Instagram Photo Resizer

Instagram feed posts work best at 1080 pixels wide. Square posts use 1080x1080 (1:1), portrait posts use 1080x1350 (4:5), and landscape posts use 1080x566 (1.91:1). Uploading at these exact dimensions prevents Instagram from applying additional compression that can degrade quality.

Instagram stories and reels use a 9:16 vertical aspect ratio at 1080x1920 pixels. Keep important content away from the top 250 pixels and bottom 450 pixels, where UI elements like your username, captions, and action buttons overlap the image.

Instagram profile pictures display at 110x110 pixels on desktop and smaller on mobile, but you should upload at 320x320 or higher for crisp rendering. The image is cropped to a circle, so keep your face or logo centered and away from the edges.

Yes. Instagram applies its own compression to all uploads. You can minimize quality loss by uploading at the exact recommended dimensions (1080px wide for feed) and using JPG at quality 85-90. Avoid uploading images larger than necessary, as Instagram will downscale and recompress them.

Use JPG for photographs, as it produces smaller files with good quality and Instagram handles it well. Use PNG only for graphics with text, logos, or transparency, since PNG files can be much larger and Instagram may convert them. This tool lets you choose your output format before downloading.

Use the Crop Image tool first to set the correct aspect ratio (1:1 for square, 4:5 for portrait, 9:16 for stories), then return to this resizer to set the exact pixel dimensions. Cropping before resizing ensures you control what stays in the frame rather than letting Instagram auto-crop.

Resizing down to Instagram dimensions from a larger original generally preserves or improves perceived sharpness because the pixels become denser. Always resize from a higher-resolution original rather than upscaling a small image, as upscaling always introduces blur and artifacts.
