YouTube 4K Video Downloader
Download YouTube videos in true 4K (2160p) Ultra HD for free — full-bitrate video with audio merged server-side into a single MP4 or WebM.
YouTube stores 4K video and audio as separate streams — which is why many downloaders silently cap out at 720p (the highest quality YouTube ships pre-combined). Puliqo fetches both streams and merges them server-side with FFmpeg, so 2160p arrives as one proper file.
After you fetch a link, every resolution the video actually offers is listed with its file size — pick 4K (2160p) if the uploader provided it, or any step down to save space.
