YouTube Downloader: Save Video and Audio

YTMP3 is a free YouTube downloader that runs in your browser, with nothing to install. Paste a video link and save it as MP3 audio or MP4 video, then keep the copy for offline use. This page explains the choice behind each format and how to tell whether a download really finished.

Download a YouTube video

Paste the YouTube link, or search by keyword if you have not found the video yet.
Decide between MP3 audio and MP4 video.
Follow the offered download and let the browser finish the transfer.
Check the downloads list, then open the finished file on your device.

Features

Audio or video, pick once

Choosing the format before you start saves a second pass. Music, podcasts and talks usually need only sound, while lessons and clips depend on what is shown. A focused audio file is lighter to store and move, and it plays in almost every player, which matters when space or bandwidth is limited. See YouTube to MP3 for the audio-only route.

Download safely

Stay on trusted pages and ignore unexpected pop-ups or files offered by other sites. Keep your browser and operating system updated so that saved items can be scanned before you open them, and treat any unfamiliar download as a risk rather than a shortcut. The habits that protect you elsewhere apply here too.

Confirm the transfer finished

A completed conversion is not the same as a completed transfer, so check the browser downloads list rather than assuming the file is ready. On phones the saved item may appear under Downloads or in a file manager instead of a media app. If a copy seems missing, look for the finished file before starting the same download again, and see the YouTube to MP4 Converter when the picture has to stay.

Frequently asked questions

Is this YouTube downloader free?

Yes. YTMP3 is free, needs no account and works on desktop and mobile browsers.

MP3 or MP4, which should I choose?

Choose MP3 for music and MP4 when the image matters. Both come from the same link.

Does it work on iPhone and Android?

Yes. As a web tool it runs in the mobile browser, and the file is saved to your device's downloads.

The transfer itself takes seconds; what matters afterwards is knowing where the file went and that it opened correctly. Keeping your browser and system up to date helps ensure that anything you save is scanned before you use it. Files you no longer need are best deleted, both for space and for tidiness.
