Which photos and logos can I select?

This tool accepts image files your browser can decode. The file never leaves your device, so there is no upload limit — the only ceiling is what your browser can hold in memory.

What pixel sizes does the tool create?

It creates 1080×1080 for Instagram square, 1080×1920 for Stories, 1200×675 for X, and 1200×630 for Facebook.

Will the full background photo remain visible?

Not always. The photo fills the selected canvas, so edges are cropped when its aspect ratio differs from the platform size.
