Video Aspect Ratio Converter
Fit a video into a new aspect ratio, with a blurred or solid-color background instead of cropping.
The original audio track is kept as-is.
The first time you use a video or audio tool, a one-time ~30 MB processing engine downloads. Runs entirely on your device after that.

About this tool
Turn a landscape video into a vertical one for Reels or Shorts, or a vertical video into widescreen — without cropping anything out. Pick a target ratio, and a blurred, black or white background fills the empty space around the original frame.
Which aspect ratios are supported?
9:16, 16:9, 1:1, 4:3 and 3:4.
Does it crop my video?
No, the whole original frame is kept and scaled to fit — the new space around it is filled with a blurred copy of the video or a solid color instead.
Is the audio kept?
Yes, the original audio track is carried over unchanged.
Is my video uploaded anywhere?
No, conversion happens entirely on your device. A one-time ~30 MB processing engine downloads the first time you use a video or audio tool.
