About Instagram Story Resizer — Free Online Tool

Instagram Story Resizer redraws a still image on the 1080 × 1920 vertical frame the code uses for full-screen Stories and Reels covers.

Only the frame changes: the picture is scaled once and drawn onto the taller canvas, cropped to cover it or fitted inside it with the bands above and below filled — by default with a blurred, darkened blow-up of the picture itself, which is what stops a landscape photo sitting in empty white on a full-screen story. It takes still pictures only — the file is decoded as an image, so a video is rejected rather than reframed, and a Reel itself still has to be exported from wherever it was edited.

Everything happens in the page you have open: the image is read into a canvas in your browser and the download comes straight back out of that canvas. No copy of it reaches a server.

Turning a landscape holiday photo into a Story that fills the screen, making a cover frame from a still you already have, and reshaping a square graphic so it is not left floating in the middle of a phone screen.
