How it works – resize by custom width
- Upload a video (MP4, MOV, WebM, etc.).
- Enter the desired width in pixels (or use a preset).
- Height is calculated automatically so the aspect ratio is preserved.
- 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.
