Features
This online YouTube video downloader saves a public video as a real MP4 file you can keep: the response contains a permanent download link plus video metadata, not a temporary redirect.
A Real MP4 File, Not A Redirect
Many downloaders hand back a short-lived CDN link that dies outside your browser. This YouTube video downloader saves the actual file and returns a permanent URL you can open from any device, at any time.
Quality Selection
Pick the resolution that fits the job before downloading. The downloader lists what the source video makes available and keeps the highest quality you choose — never a re-compressed surprise.
Every Public Link Shape
Watch pages, youtu.be short links, Shorts URLs, and embeds all resolve. Only private, deleted, and age-restricted videos fail, and the downloader tells you instead of retrying blindly.
Permanent Download Links
The download URL points to a fully saved file, so you can copy it to another device, hand it to a media server, or keep it in notes — it does not expire after you close the tab.
Video Metadata Included
Every download returns the video title, duration, thumbnail, and file size alongside the link — enough to confirm you grabbed the right file before you move it anywhere.
Free With An Account
The tool runs on your AgentBody account, which is free to create and includes starter credit. Each download draws a small, fixed amount from your balance — the price is shown on the pricing page.
How to use
Download a YouTube video online in three steps.
Copy The Video Link
Open the video on YouTube and copy its URL from the address bar, or tap Share → Copy Link in the app. Watch pages, Shorts, and youtu.be links all work.
Sign In With A Free Account
Open the downloader and sign in with a free AgentBody account. The account ties downloads to your usage and unlocks the same endpoint via API.
Paste The Link
Paste the YouTube URL into the input field. The downloader validates the link before starting, so malformed URLs are rejected immediately.
Choose The Quality
Review the available resolutions and pick one. Higher resolutions mean larger files; the downloader shows what the source offers so you can choose deliberately.
Run The Download
Start the download and wait for the file to be saved. Short clips finish in seconds; longer videos take proportionally longer because the file is fully stored, not just linked.
Save The MP4
Open the returned download link to save the MP4 to your device. The link is permanent, so you can also copy it to another machine or hand it to a media server.
Frequently asked questions
Is this YouTube video downloader free to use?
The downloader runs on your AgentBody account, which is free to create and includes starter credit. Each download draws a small, fixed amount from your balance — the exact price is shown on the pricing page, and failed downloads are not billed.
What quality can I download YouTube videos in?
The downloader offers the resolutions the source video makes available and keeps the quality you pick without re-compression. The maximum depends on how the video was uploaded — not every video has every resolution.
Do I need to install software to download YouTube videos?
No. The downloader runs entirely in your browser on desktop and mobile. Paste the link, pick a quality, and open the download link — no app, extension, or YouTube login required.
Can I download age-restricted or private videos?
No. The downloader accesses public videos only. Private, deleted, age-restricted, and region-blocked videos cannot be fetched by any third-party tool without the owner's permission.
Why does the download link not expire?
The MP4 file is fully downloaded and stored, and the response points at that saved file rather than a temporary YouTube CDN address. The link works from any device and any network, later.
Is it legal to download YouTube videos?
Download only content you own, have permission to save, or have another lawful basis to download — such as your own uploads or Creative Commons material. Respect copyright law and YouTube's terms of service.
