How it works

  1. Choose a video file
  2. Select the target resolution height
  3. Re-encode locally and download the resized MP4

Use cases

  • Shrink 4K footage to 1080p for sharing
  • Prepare clips for platforms with resolution limits
  • Reduce playback problems on older devices

Supported formats

Input: MP4, WebM, MOV

Output: MP4

Limitations

  • Downscaling always re-encodes, so a small quality loss is expected; upscaling is not supported.
  • Safari cannot encode VP9 or AV1, so H.264 output is used where available.
  • Files up to 250 MB are supported; larger videos may exceed your device memory.

Privacy

Processing happens locally in your browser. Your file is not uploaded to iAgent7 Tools or a third-party API.

File names, file contents, and results are not sent to analytics or error logs.
