About this tool
Fit landscape or portrait video within a square of 480, 720 or 1080 pixels, retaining its aspect ratio with even pixel dimensions. Videos are only reduced; a smaller video keeps its size. The result is H.264 MP4 with the first audio track converted to AAC when present. The video engine downloads about 30 MB on first use. Files are processed locally.
How to use Resize Video
- Choose a video under 2 GB.
- Choose the maximum dimensions for the resized video.
- Select Resize video and download the MP4.
Frequently asked questions
Will the video become a square?
No. Both dimensions fit inside the chosen square while the aspect ratio is retained, subject to even-pixel rounding.
Will a smaller video be enlarged?
No. Videos are only reduced to fit the chosen size. A video already smaller than the chosen box keeps its size, subject to even-pixel rounding.
Are all tracks preserved?
The first video and first audio track are converted. Additional audio tracks, subtitles and attachments are omitted.
