Copy the link to one video
Open the individual YouTube video that you own or have permission to download and use its Share control to copy the link. A youtube.com/watch?v= address or a youtu.be short link identifies one standard video. A channel, playlist or live page does not identify a supported finished file. Paste the copied URL into the downloader form above and select Analyze link.
Choose a format your phone can use
Wait for the actual video choices before tapping Download. MP4 is usually the simpler choice for broad phone compatibility when it appears; WebM playback depends on the device and app you use. The listed resolution and size come from the analyzed upload, so do not assume every phone or video will have the same 1080p or 4K option. Large files may exceed this service's 512 MB processing limit.
Save and find the completed file
Keep the browser tab open while the file is prepared, then use its temporary download link. On iPhone or iPad, check the browser's downloads list and the Files app location configured for downloads. On Android, check the browser's download list or your device's Downloads location. Browser settings can change those destinations; saving the file does not automatically place it in the Photos gallery.
Only download content you own or have permission to use. No login, paywall, DRM, or private-access bypass is offered.
Questions about this topic
Do I need an app?
No. Use the downloader in a current mobile browser; the browser handles the saved file.
Why is the file missing from Photos?
A browser download is normally saved to its configured files location. Find it in browser downloads or your device's file manager, then import it into another app if needed.
Can I download a private video on my phone?
No. The public extractor cannot use your YouTube sign-in or bypass private, age, region or purchase restrictions.
