AI Reframe Video
Upload a video and choose your target aspect ratio. AI will detect the main subject and keep it centered while reframing.
AI Reframe Video — resize video online & convert to vertical for free
Our free AI video reframe tool lets you instantly resize video online and change the aspect ratio of any clip — without opening Premiere, After Effects or DaVinci Resolve. Upload a video, pick a target ratio (16:9, 1:1, 9:16 or 4:5), and the AI automatically tracks the main subject — faces, motion and objects — to keep it perfectly centered while it crops.
Whether you need to convert video to vertical for TikTok, square it up for Instagram, or repurpose a horizontal podcast clip into Reels and Shorts, this reframe video tool turns hours of manual editing into seconds of click-and-export workflow.
How AI video reframing works
Behind the scenes, three steps happen automatically on every frame:
- Subject detection — the AI finds faces, people and key objects in each frame.
- Smart tracking — a temporal moving average smooths the crop window so it follows the action without jittering.
- Auto crop & export — your video is re-cropped to the target aspect ratio and exported, ready for any platform.
The result: a clean, centered video that looks like it was shot in that ratio from the start.
