Frequently Asked Questions (FAQs)
Q: Does resizing a video reduce its file size?
A: Yes! Downscaling a video from 4K (2160p) or 1080p to 720p or 480p significantly reduces the number of pixels per frame, resulting in a much smaller file size suitable for messaging and web streaming.
Q: Which video resolution is best for website embedding?
A: 1080p (1920x1080) and 720p (1280x720) are the gold standards for web embedding, offering crisp visual quality while minimizing bandwidth usage and buffering times.
Q: Are my personal video files uploaded to remote servers?
A: No! All video scaling and frame rendering run 100% locally in your web browser memory. Your personal recordings and clips never leave your device.
Q: Can I resize vertical videos (e.g. 9:16 aspect ratio)?
A: Yes! The tool scales vertical phone videos proportionally while maintaining the correct aspect ratio without stretching.
Q: Does OnlineConverter add watermarks to resized videos?
