About Video Resolution Changer

Resize videos to any resolution from 360p to 4K, with custom dimensions and multiple scaling modes.

How to use Video Resolution Changer

  1. 1Upload a video file.
  2. 2Select a target resolution preset (360p, 480p, 720p, 1080p, 4K) or enter custom dimensions.
  3. 3Choose the scale mode: Fit (letterbox with black bars), Fill (crop to fill), or Stretch.
  4. 4Select the output format.
  5. 5Click Convert and download the resized video.

Tips

  • Downscaling to 720p is often enough for social media and significantly reduces file size.
  • Use Fit mode to preserve the original aspect ratio — Fill mode crops the edges to fill the frame.
  • Upscaling (e.g., 720p to 4K) increases file size but does not add real detail — avoid it unless required.
  • Stretch mode distorts the image to fill the exact dimensions — use it only when aspect ratio does not matter.
