Free YouTube to MP3 and MP4 converter
CNVMP3 is a free online converter that turns YouTube videos into MP3 audio or MP4 video. MP3 is already selected when the page opens, so most of the time you only paste a link and tap Convert. Before you download anything, you see the video, its length and the real list of qualities it offers. It works the same on an iPhone, an Android phone or a computer, with no app to install and no account to create.
Your link is used only to find the files you asked for. We don't keep it, we don't build a history of what you convert, and nothing is stored on our side. Each quality is a direct download link, so you tap the one you want and the file opens in a new tab, while this page stays right where it is for your next video.
What you can convert
Every link gives you MP3 audio and up to six video qualities. This is the full list, in the order you see it in the converter.

Each MP4 quality shows its file size before you tap it. Not every video has every quality, so you only see the ones your video offers.

Why use CNVMP3
Free, with no account
Every conversion is free. There is nothing to sign up for and no login screen between you and your file.
MP3 ready by default
MP3 is already selected when the page opens, with 320 kbps marked as the best choice. If you want the video instead, MP4 is one tap away.
See the qualities first
After you paste a link, you get the real list of options for that video. MP4 qualities show their file size before you tap them.
Video up to 1080p
Pick anything from Full HD 1080p down to 144p. Lower video qualities usually make smaller files, which helps on mobile data.
Made for your phone
The converter is built for small screens first. It runs in Safari and Chrome, so there is no app to install.
Shorts and YouTube Music links
Paste a Shorts link or a YouTube Music link just like a normal video link. CNVMP3 reads them the same way.

Can I convert YouTube Shorts and YouTube Music links?
Yes. Shorts links and YouTube Music links work like any other video link. Copy the link with the Share button, paste it into the box and pick MP3 or MP4. Shorts get a tall preview, so you can see you have the right one.
Can I convert long videos?
Yes. Long mixes, full albums, podcasts and movie-length uploads all work. Each MP4 quality shows its file size before you tap it, so you can pick a smaller quality when you want to save space or mobile data.
Where is my file saved on an iPhone or iPad?
When the file opens in a new tab, tap the Share button and choose Save to Files, or use the download option if Safari shows one. Saved files go to the Downloads folder in the Files app, where you can open or move them.
Where is my file saved on Android or a computer?
If the file starts playing in a new tab, open the browser menu (⋮) and tap Download. On Android it goes to the Download folder, which you can open from the Files app. On a computer it goes to your Downloads folder unless you chose another place.
Why didn't my download start?
The file opens in a new tab, and some browsers play it there instead of saving it. Use the browser menu to download it. Some apps also open links in their own small browser, so open this page in Chrome or Safari. Private, removed or blocked videos can't be converted.
