Video Resize Tool

This tool resizes videos online by adjusting dimensions while preserving important content. Users provide a source video, a target width and/or height or an aspect ratio, choose an output format, and run the process to obtain a resized file. Conceptually, it computes target dimensions, applies aspect-ratio constraints, and chooses between cropping or adding letterbox padding before re-encoding. The service supports multiple common formats and codecs, enabling quick delivery of assets suitable for websites, social feeds, and presentations. Beneficiaries include videographers, marketing teams, educators, and freelance editors who must meet platform-specific size requirements with minimal workflow disruption. The tool’s value lies in loss-aware resizing, clear dimension controls, and predictable outputs without requiring desktop software. Core features include: dimension calculation from width/height and aspect ratio, optional crop-to-fit vs letterboxing, selectable output format (MP4/WebM), and standard codecs for broad compatibility. It also returns actual dimensions and file size estimates to verify results. Typical use cases involve resizing a 16:9 video to square for Instagram, or adapting a 4:3 clip for widescreen platforms, ensuring consistent delivery across channels.
