Frequently Asked Questions

What platforms are supported?

We support all major platforms: Instagram (post, story, portrait), Facebook (post, cover), Twitter/X (post, header), LinkedIn (post, cover), and YouTube (thumbnail, banner).

What's the difference between fit modes?

Cover fills the entire frame (may crop), contain fits the whole image (may add borders), and stretch distorts the image to fill.

Are my images uploaded anywhere?

No, all image processing happens locally in your browser. Your images never leave your device.
