Why resize video with Tools Root
Different platforms enforce different resolution expectations — a mobile app might want 720p to save bandwidth, an archival copy might target the original 4K, and a specific ad placement might require exact custom dimensions. Resizing gets your video to whatever the destination requires.
Presets for speed, custom dimensions for precision
Standard resolution presets cover the common cases quickly, while fully custom width and height inputs handle specific requirements a preset wouldn't match.
Common use cases
Downscaling a 4K video to 1080p for faster uploading, resizing a video to match a specific platform's recommended dimensions, preparing a smaller-resolution version for mobile viewing, or standardizing a batch of videos from different sources to one consistent resolution.
