Downloading preserves the original video quality selected. If you choose 4K, you'll get the highest-quality version available for that video, subject to the uploader's licensing and YouTube's encoding.
File sizes depend on duration, bitrate, and codec. Expect roughly 300 MB to several GB for longer clips at 4K; shorter clips will be smaller. You can compare against lower resolutions to see the trade-off between quality and size.
Choosing 4K vs. 1080p or lower resolutions offers better detail but larger file sizes. For devices with smaller screens or limited bandwidth, 1080p may be a better balance between quality and file size. The 4K downloader also presents options to select different codecs (HEVC vs AVC) depending on device compatibility. If you need smaller files with acceptable quality, consider 1080p or 720p options.
