About Resize Video
Resize video files to any resolution –entirely in your browser. Choose from common presets (1080p, 720p, 480p, 360p) or enter custom dimensions. Lock the aspect ratio to prevent distortion. This tool is essential for preparing videos for specific platforms, reducing file size by downscaling, or standardizing video dimensions across a project. Uses FFmpeg for local processing –your videos never leave your device.
Frequently Asked Questions
What resolution should I use?
1080p (1920x1080) for full HD, 720p (1280x720) for web sharing, 480p (854x480) for mobile-first situations.
Will upscaling improve quality?
No. Upscaling a 480p video to 1080p increases the file size but does not add detail. Only downscale for best results.
Does aspect ratio lock work?
Yes. When locked, changing width automatically adjusts height proportionally to prevent stretching.
