4:5: Video Reframer

Reformat any video for Instagram in seconds. 4:5, 1:1, or 9:16. Batch multiple clips at once. Runs entirely on your phone. No account, no upload.

Reformat any video for Instagram carousels without losing a single frame.

4:5 takes whatever you shot, portrait, landscape, square, or vertical phone video, and fits it inside the aspect ratio you need on a canvas of your choice. Your full shot stays in frame. No cropping, no lost footage, no annoying color issues and editing.

WHAT IT DOES • Fits your video inside a 4:5, 1:1, or 9:16 canvas with no cropping • Exports at 1080p or 4K • Lets you pick white or black as the background color • Handles multiple clips in one batch • Preserves HDR source material where supported • Saves directly to your Photo Library

WHAT IT DOESN'T DO • No account. Nothing to sign up for. • No uploads. Everything happens on your device. • No analytics. No tracking. No ads. • No subscription. The app is free.

Built for creators who shoot horizontally but post vertically, who want their whole frame in the shot, and who don't feel like rethinking their feed every time a platform changes the default ratio.
