Question 1

What is the best image resolution for Instagram posts?

Accepted Answer

The recommended resolution for square feed posts is 1080 × 1080 pixels (1:1 ratio). For portrait posts that take up the most vertical space on mobile phones, use 1080 × 1350 pixels (4:5 ratio). For Stories and Reels, use 1080 × 1920 pixels (9:16 ratio).

Question 2

Why does Instagram make my photos look blurry?

Accepted Answer

If you upload an image larger than 1080 pixels wide or in an unsupported aspect ratio, Instagram's aggressive compression engine automatically shrinks and recompresses it. By resizing and cropping to exact dimensions in Forma beforehand, you retain control over sharpness.

Question 3

Are my photos or images uploaded to remote servers or cloud storage?

Accepted Answer

No. Forma runs 100% locally in your browser using HTML5 Canvas, WebAssembly, and modern Web APIs. Your photos never leave your device, ensuring complete privacy for sensitive personal pictures, unreleased product photos, and confidential documents.
