Video Resolution Changer

What is Video Resolution Changer?

Video Resolution Changer lets you downscale or upscale your video to common resolutions like 480p, 720p, 1080p, or 4K. Useful for reducing file size before sharing, meeting platform upload limits, or standardizing footage. All processing is private and runs locally via ffmpeg.wasm.

How to use

1. Upload your video file (MP4, WebM, or MOV).
2. Select a target resolution from presets (360p, 480p, 720p, 1080p, 1440p, 4K) or enter a custom width and height.
3. Click Resize and download the resized video.

Result

Your phone recorded a 4K video that's 2 GB. Select 1080p to shrink it to a manageable size for email while keeping sharp detail.
