Use this tool to upscale or downscale video dimensions while keeping control of file size and compatibility for playback, editing, or social sharing.

Downscale to 720p or 1080p to shrink file size with minimal quality loss.
Use 4K output only when the source quality supports it.
Upscaling helps compatibility and screen fit, but it cannot recreate fine detail missing in the source.
Pair resolution changes with bitrate tuning for better quality-to-size results.

These tools improve and reformat the video data you already have, but they cannot invent missing real detail that was never captured in the original file.
Frame-rate changes (for example 30fps to 60fps) can make motion smoother, but on low-motion scenes the output may still look very similar.
Final results depend on source quality, scene motion, and playback screen size, so short test clips are the best way to pick perfect settings.
