How it works – fit inside a box
- Upload a video (MP4, MOV, WebM, etc.).
- Set the maximum width and height of the target box (or use a preset).
- The video is scaled so it fits entirely inside the box while keeping its original aspect ratio.
- Optionally adjust quality/FPS in the Settings panel.
- Click “Resize & Download” – the video is re-encoded at the new size.
Privacy: All processing is local. Your video never leaves your device.
