Frequently Asked Questions
What is the ideal image size for Instagram?
Instagram recommends 1080×1080 for square posts, 1080×1350 for portrait, and 1080×566 for landscape. Upload at the highest quality to avoid compression artifacts.
Does resizing change the aspect ratio?
No. When you enter a target width, the height is automatically calculated to preserve the original aspect ratio. This prevents stretching or squishing your image.
Is my image uploaded to a server?
No. All resizing is done using the HTML Canvas API directly in your browser. Your images never leave your device and are never stored on any server.
