any good YouTube to MP3 converters on the web?

Trying to convert youtube videos to mp3 files on my phone, the website I had been doing it on is down and all the alternatives are scam sites and virus links. Any alts you know?

Edit: i have an iPhone, I would prefer a browser based converter if possible.

Don't be a newb. Learn the command line and use yt-dlp.
https://ytdlp.online/

Paste link

Select preset

Run

Press "Download" link inside the black box
Try cobalt.tools. It does what you want to do inside a browser tab (although I only used it on desktop so far), but it might work with an IPhone as well. You can convert YouTube links into either mp3, ogg, wave and opus files (with various bitrates), or mp4 or webm video files (with various resulutions). I use it constantly.
- It does. Thank you.
I'm using yt-dlp. Its a command line app, but quite easy to use. It's primary function is downloading entire videos, but it can rip out audio into various formats as well.

Edit: I'm apparently bad at reading, didn't notice you're looking for a phone app. NewPipe has has a video and audio download functions.
- I should mention it’s for an iPhone specifically. I used to use web based converters but they are taken down
  
  You can absolutely use yt-dlp on iPhone though via a-shell.
  
  You can just install it and then type pip install yt-dlp.
  
  We do this.
- Can yt-dlp download adult restrictioned videos?
  
  Yes but you will have to take extra steps to supply a valid cookie from a signed in account: https://github.com/yt-dlp/yt-dlp/issues/11296#issuecomment-2466538349
  
  I'll admit I haven't checked, but I haven't run into any restrictions so far
can recommend YTDLnis, as others have. If web-based is important to you, cobalt dot tools seems great and trustworthy.
- Banger, cobalt works great, thank you so much.
Seal GUI android frontend for yt-dlp and can convert to mp3 https://f-droid.org/packages/com.junkfood.seal/
YTDLnis

Android GUI for yt-dlp, which can download Videos from many websites. You can only dowload audio aswell
self-host a downloader/extractor site for your own use, behind authentication (so it's for you only, not randoms off the internet that 'find' it).
I'm using a browser plugin called DownloadHelper but I haven't checked if the iPhone version of the browser supports the plugin or not

If it wasn't on your phone, I would point to yt-dlp: simply type yt-dlp -F <Youtube URL> to list the available formats, then yt-dsp -f <format ID> <Youtube URL> to download the audio in the format of your choice:

E.g.:

$ yt-dlp -F https://youtu.be/xWUCsE4IM_c

yt-dlp can be used on an iPhone via a-shell (and possibly other shell apps).
interactive mode is nice and basically combines those steps, and i tend to use it for one-off downloads of a single url. that way i get to see what i'm gonna get (filesize, resolution, codec, etc), before i get it.

yt-dlp -f - https://youtu.be/xWUCsE4IM_c

then at the prompt here in your example, i'd input 140 for audio only.

If an app works for you then try out Seal
