Yes! All resizing happens locally in your browser. Your videos never leave your device or get uploaded to any server.
We support MP4, WebM, MOV, and MKV formats. The resized video will maintain the same format as the original.
Upscaling (making larger) may reduce perceived quality. Downscaling (making smaller) typically maintains good quality while reducing file size.
When enabled, changing width automatically adjusts height (and vice versa) to keep the video's proportions intact, preventing distortion.
