how to download from YouTube
- Copy the YouTube link. Tap Share under the video or Short and choose Copy link, or copy the URL straight from your browser address bar.
- Paste it into FastSaver. Drop the link into the box on fastsaver.io — YouTube is detected automatically. On mobile, the paste-from-clipboard button saves you a step.
- Pick a quality or flip to MP3. Choose a resolution from the quality picker — typically 720p, 1080p, or 4K, depending on what the source offers. Want just the sound? Switch on the audio-only toggle for an MP3.
- Press download. The file saves with a proper filename. On iPhone it lands in the Files app; on Android and desktop it goes to your Downloads folder.

YouTube hosts everything from full-length tutorials to fifteen-second Shorts, and FastSaver handles both. Paste any public video or Shorts link and you get a quality picker showing exactly what the source offers — usually 720p, 1080p, and sometimes 4K — so you can balance file size against sharpness before you commit. If you only need the sound, the audio-only toggle skips the video entirely and hands you an MP3 with a clean filename. Our step-by-step guides cover the details: see how to download YouTube videos and how to convert YouTube to MP3.
Shorts work exactly the same way as regular videos — copy the share link, paste, download. Since Shorts are vertical and often watched on phones, it helps that FastSaver runs entirely in your mobile browser with no app to install; the walkthrough in how to download YouTube Shorts shows the whole flow on iPhone and Android. Note that private videos, live streams, and playlists are not supported — FastSaver works with one public video link at a time.
A quick word on doing this right: download for personal, offline use — your own uploads, openly licensed videos, or content you have permission to save — and respect creators and YouTube's terms of service. If you also save clips from other platforms, FastSaver covers TikTok, Instagram, Facebook, X, and Pinterest with the same paste-and-download flow.
YouTube downloader — frequently asked
What resolutions can I download?
Whatever the source offers — typically 720p, 1080p, and up to 4K when available.
Can I download YouTube as MP3?
Yes. Switch on audio-only and you’ll get an MP3 instead of a video file.
Do YouTube Shorts work?
Yes — Shorts links are supported the same way as regular videos.
Is this legal?
FastSaver is for downloading content you own or are permitted to save, for personal use. Respect creators’ rights and YouTube’s terms.
Can I download an entire YouTube playlist or channel at once?
No — FastSaver works with one video link at a time and does not support playlists, channels, or batch downloads. To save several videos, paste each link separately and download them one by one.
Where do YouTube downloads go on my iPhone or Android phone?
On iPhone and iPad, downloads land in the Files app — Safari shows a download arrow when the file is ready, and you can move a video to Photos via the Share sheet. On Android, files go to your Downloads folder.
Does FastSaver add a watermark or logo to downloaded YouTube videos?
No. FastSaver never adds watermark overlays, logos, or branding to your files. The video downloads as the source provides it, saved with a proper filename.
Can I download a YouTube live stream while it is still live?
No — live streams are not supported. FastSaver also cannot access private or removed videos. It works with regular public videos and Shorts.
