Video Size Converter

This tool enables precise resizing of video assets to Instagram presets, addressing the need for consistent aspect ratios across reels, stories, and feed posts. It accepts a source video and a target IG format, then outputs a ready-to-upload MP4 file that matches the selected dimensions. Conceptually, the process involves mapping Instagram presets to standard resolutions, selecting a crop strategy, and re-encoding the video with appropriate bitrate and codec settings. It is designed for social media managers, creators, and teams who require repeatable, platform-aligned outputs without manual frame-by-frame edits. The system emphasizes deterministic results: the output resolution, crop behavior, and encoding parameters are clearly defined and repeatable across multiple videos. Unique value lies in combining preset-based resizing with optional overrides (resolution, bitrate, frame rate) while maintaining quality and compliance with IG's framing guidelines. Core features include preset mappings for reels (9:16), stories (9:16), and feed (1:1 or 4:5), fit vs crop options, and sensible defaults for encoding. Use cases range from repurposing long-form content into IG-friendly clips, producing batch-ready assets for campaigns, to converting client deliverables for social delivery. Outputs provide metadata such as final resolution, duration, and estimated file size to aid planning and upload scheduling.
