Frequently Asked Questions

What is the best size for Instagram?▾

Square: 1080×1080px. Portrait (more feed space): 1080×1350px. Stories and Reels: 1080×1920px.

What do Cover / Contain / Stretch do?▾

Cover fills the frame and may crop slightly. Contain fits the full image with letterboxing. Stretch forces the image to fill the frame exactly, which may distort it.

Are my images uploaded to a server?▾

No. Everything runs locally in your browser. Your images never leave your device.

Is this tool free?▾

Yes — 100% free, no signup, no watermarks, no limits.
