Frequently Asked Questions
What is the standard Instagram post size in pixels?
The standard square Instagram post size is 1080 × 1080 pixels (1:1 aspect ratio). Instagram also supports vertical portrait posts at 1080 × 1350 pixels (4:5 ratio) and landscape posts at 1080 × 566 pixels (1.91:1 ratio).
How do I resize an image to 1080×1080 pixels online for free?
Upload your image in the tool above. The dimensions are pre-set to 1080 × 1080 pixels. Use the Crop tab if you want to frame a rectangular photo into a 1:1 square first, or click Resize Image to export your 1080 × 1080 px photo immediately.
Can I use a 1080×1080 px square image for WhatsApp DP and profile pictures?
Yes. Because WhatsApp DP, Instagram profile photos, LinkedIn profile pictures, and Facebook profile avatars all use a 1:1 square frame, a crisp 1080 × 1080 pixel image works across all of them without distortion.
How do I avoid Instagram compressing my photo and making it blurry?
Instagram automatically re-compresses images wider than 1080 pixels. Resizing your photo to exactly 1080 pixels wide in high-quality JPG format before uploading prevents aggressive platform downscaling.
Can I batch-resize multiple carousel images to 1080×1080 px?
Yes. Upload up to 10 carousel slides at once and resize all of them to uniform 1080 × 1080 pixel dimensions in one click.
Is my photo uploaded to any server?
No. All resizing and cropping happen directly in your browser on your phone or computer. Your images never leave your device.
