What image sizes does Instagram use?

Square posts: 1080×1080, Portrait posts: 1080×1350, Stories/Reels: 1080×1920, Profile pics: 320×320.

Are my images uploaded to a server?

No. All resizing happens in your browser using the HTML5 Canvas API. Your images never leave your device.

What happens if my image is smaller than the target size?

The tool will upscale to fill the dimensions. For best results, start with images at least as large as your target size.
