How to use

  1. 1Upload your video by dragging and dropping it into the dropzone or clicking 'Browse Files' (supports MP4, MOV, WebM, MKV, AVI).
  2. 2Select a target dimension: pick a social preset (e.g. TikTok 9:16, YouTube 16:9, Square 1:1), enter custom width & height, or choose a percentage scale.
  3. 3Choose how the video fills the frame: 'Blur fill' (blurred copy behind it), 'Cover' (crop to fill; pick which part stays), 'Fit' (padding bars) or 'Stretch'. The live preview shows the result.
