FAQ

What size should an Instagram post be?

1080×1080 pixels (a 1:1 square) is Instagram's ideal post size. Stories and Reels are 1080×1920 (9:16). This tool exports both exactly.

Will resizing lower the quality?

No noticeable loss — we export high-quality JPEG at the exact size, which actually looks better than letting Instagram re-compress an oversized upload.

Is my photo uploaded?

Never. Everything happens in your browser — your photo stays on your device.
