About this tool
Does this resize my video?
No. It calculates dimensions only. Use a video editor or encoder to resize or crop the actual file.
Why round to even pixels?
Even dimensions are commonly accepted by video encoders and chroma-subsampled formats. Your destination may specify a different size.
Will the result crop my image?
No. It fits the chosen ratio inside the maximum box and may leave unused space. Cropping is a separate editing decision.
