What is Video Resizer?
Video Resizer scales video dimensions to standard web resolutions (1080p Full HD, 720p HD, 480p SD) or custom pixel dimensions. It allows you to reduce video resolution to shrink file weight or fit specific display containers.
Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.

- Maintains aspect ratio lock to prevent video stretching or distortion
- Hardware-accelerated canvas resampling for smooth video playback
