What size should an Instagram photo be?

For feed posts, Instagram recommends 1080 × 1350 px for portrait (4:5 ratio), 1080 × 1080 px for square (1:1 ratio), and 1080 × 566 px for landscape (1.91:1 ratio). Stories and Reels use 1080 × 1920 px (9:16 ratio).

What is the Instagram portrait aspect ratio?

Instagram portrait posts use a 4:5 aspect ratio with recommended dimensions of 1080 × 1350 pixels. This vertical orientation occupies the maximum visible screen real estate on mobile feeds.

What is the Instagram square aspect ratio?

Instagram square posts use a 1:1 aspect ratio with standard dimensions of 1080 × 1080 pixels.

What is the Instagram landscape aspect ratio?

Instagram landscape posts use a 1.91:1 aspect ratio with standard dimensions of 1080 × 566 pixels.

Can I resize an image without stretching it?

Yes. Our tool uses smart cropping and framing. In 'Fill' mode, the image fills the crop area proportionally. In 'Fit' mode, the entire photo is preserved with a blurred ambient backdrop.

Can I crop my photo for Instagram?

Yes. The interactive viewport lets you pan, drag, and zoom (100% to 300%) with rule-of-thirds composition guidelines.

Can I resize a landscape photo to portrait?

Yes. Selecting Portrait mode (4:5) allows you to crop the focal center or select 'Fit' mode to place the landscape photo over a matching ambient background.

Can I resize an image to 1080 pixels?

Yes. All our Instagram presets are calibrated to 1080 pixels in width to match Instagram's high-definition upload resolution.

Can I adjust the image quality?

Yes. You can adjust the JPG quality slider from 1% to 100% (default 90%) to balance crisp clarity and optimized file size.

Can I reduce the image file size?

Yes. You can enter an optional Target File Size (KB) limit, and our iterative compression engine will optimize JPEG quantization to match it.

Can I use the tool on mobile?

Yes. The resizer is fully responsive and supports touch drag and zoom on Android, iPhone, and iPad.

Does the tool upload my images to a server?

No. All cropping, resampling, and encoding take place 100% locally inside your web browser using HTML5 Canvas. Your photos never leave your device.
