Video Size Converter

This tool computes target video frame sizes from given input dimensions and aspect ratios, designed for video editors, motion graphics artists, social media managers, and content producers. It helps prepare assets for platforms with strict dimension requirements, reduces trial-and-error resizing, and clarifies whether resizing will introduce letterboxing or cropping.
Conceptually, you provide input_width_px, input_height_px, and either a target_width_px/target_height_px or a desired aspect ratio. The tool offers 'fit' (preserve AR with padding if needed) and 'fill' (crop to fill) methods. It then outputs final_width_px, final_height_px, and flags for cropping or padding, plus optional preset recommendations.
Unique value comes from handling common edge cases: non-integer results are rounded, and the tool warns about upscaling beyond intended quality. It supports multiple aspect targets (16:9, 4:3, 9:16) and maintains consistent units in pixels. It avoids encoding changes, focusing purely on frame sizing and delivery readiness.
Use cases include preparing YouTube or Instagram videos, adapting cinematic footage for social clips, or exporting batch assets for editors. Users gain speed, consistency, and fewer errors when delivering to diverse platforms.
