Video Crop to Square follows a deterministic conversion flow so results are repeatable and easier to troubleshoot when a file behaves unexpectedly.
Crop a video to a specific aspect ratio, removing unwanted borders or backgrounds.
All uploads are processed on secure, encrypted ConvertCraft servers within isolated containers. Your original video files are never modified — we work on copies. Every uploaded file and processed output is permanently deleted from our servers immediately after processing, with no backups or caching retained.
This tool uses FFmpeg's crop filter to extract a rectangular region from each video frame based on a target aspect ratio and anchor position. The crop filter syntax is crop=width:height:x:y, where x and y are calculated from the selected gravity (center, top, bottom, left, right). The tool computes the largest possible crop rectangle that fits the target ratio within the source dimensions, then positions it according to the anchor. Supported ratios include 16:9, 9:16, 1:1, 4:3, and 4:5 — covering all major social media and broadcast specifications.
Essential for repurposing landscape video for portrait-first platforms — crop 16:9 footage to 9:16 for TikTok, Reels, and YouTube Shorts without adding black bars. Also ideal for creating 1:1 square crops for Instagram feed posts, 4:5 vertical crops for Instagram and Facebook feeds, or removing unwanted edges and backgrounds from screen recordings. Perfect when you need the output to completely fill the target frame without any padding.
