Large videos can run out of memory on phones.
Changing the picture uses your browser's own video encoders. Recent Chrome and Edge can write H.264, VP9 and AV1; Firefox and older Safari lack some encoders, so the tools offer only what your browser can produce and say so when something is missing.

How to use Resize video
Choose a video or drop it on the page.
Pick 1080p, 720p or 480p, a shape (Square 1:1, Portrait 9:16 or Landscape 16:9), or Custom to type a width and height.
For a shape or custom size, choose Fit, Fill and crop or Stretch for when the shape differs.
Select Resize video, then download the result.
Questions
Pick Portrait 9:16 (1080 by 1920 pixels) or Square 1:1 (1080 by 1080). Fit keeps the whole picture and adds bars, and Fill and crop fills the frame and cuts off the edges.
For 1080p, 720p and 480p, yes. For a shape or a custom size, it depends on the fit mode: Fit and Fill and crop keep the proportions of the picture, and Stretch changes them.
No. Everything runs in your browser on your own device, and the video is never uploaded.
