Change video resolution online
Rescale your video to 1080p, 720p, 480p and more — right in the browser, free and without watermarks. The video never uploads to a server.
How it works
- Pick a video — it opens right in your browser, nothing uploads to a server.
- Choose the new resolution. Width is calculated automatically, proportions stay intact.
- Press “Change resolution” and download the result.
Limitations
The video is re-encoded at high quality, so the operation takes time — roughly like compression. Upscaling works but adds no detail: the picture gets bigger, not sharper. Speed depends on your device; very large files are safer to process on a desktop.
