Copy the YouTube URL: Head to YouTube, open your video, and copy the link from the address bar.
Paste into the Converter: Open your chosen tool (like YTMP4 or OnlineVideoConverter) and paste the link.

YouTube to MP4 HD and 4K: What You Need to Know

Not all YouTube videos are available in HD or 4K—it depends on what the uploader provided. To check:

Open the YouTube video and click the “Settings” gear.
Select “Quality” to see the highest resolution available.
Use a tool like 4K Video Downloader to match that quality when converting.

If a video maxes out at 1080p, even the best YouTube to MP4 converter can’t magically upscale it to 4K.

Personal use (e.g., tutorials, public domain content).
Videos you’ve created or have permission to download.
