Aspect Ratio Converter

Reshape a video for Reels, Shorts, TikTok, feeds or YouTube, with blurred edges, black bars or a crop. Free, no sign-up, and nothing is uploaded.

How to use it

  1. Choose a video.
  2. Pick the shape you need.
  3. Choose how to handle the leftover space: blurred background, black bars or a crop.
  4. Press Aspect Ratio Converter and download the result.

It runs on your device, so big files take longer on slower computers and phones. Nothing is uploaded or stored.

Got a long video? Let Renafy find the clips.

Upload a stream or podcast and get captioned clips ready to post, in the shape you pick. Plans from $13 a month, cancel anytime.
