Frequently Asked Questions
What is the best Instagram post size?
The optimal Instagram post size is 1080×1350 pixels (4:5 aspect ratio). This portrait format maximizes screen space in the Instagram feed and provides better engagement.
Can I use square images for Instagram posts?
Yes, Instagram supports 1080×1080 square images. However, 1080×1350 (4:5 vertical) takes up more feed space and typically gets better visibility.
Does resizing reduce Instagram image quality?
Our AI resizer maintains maximum quality during the resize process. Instagram may compress images on upload, but starting with the correct 1080×1350 size minimizes quality loss.
Can I batch resize multiple Instagram posts?
Yes! Upload multiple images at once and our AI will resize all of them to 1080×1350 simultaneously, perfect for planning your Instagram grid.
What file formats work for Instagram posts?
Instagram supports JPG, PNG, and WebP formats. Our resizer accepts all three and outputs high-quality images ready to post.
