Cobalt is great, it's entirely web based and supports many websites. You can download both audio and video (if available).

It's not a mobile client sadly, but for desktop I've always liked "4k video downloader" (Softonic). It's something you have to download on there, but I copy the youtube link, open the app have it parse the link and then it's downloaded and ready in .mp4 pretty quickly, with .mp3 as an option too for music.
It's a bit convoluted, but I'll usually download albums and tracks on my PC, have it all saved in a music folder then copy it manually to my phone.
If you are willing to follow the self-hosted route metube is a browser based converter and has yt-dlp as backend :) easy to use (once you get everything setup !).
No scam, virus issues, can even download a whole playlist, video...
Don't be a newb. Learn the command line and use yt-dlp.
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 don’t know if newpipe specifically has this issue but I know as of a few months ago freetube can’t download higher than 360p. Seemed to be linked to some update Google pushed.
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.
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.
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/
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

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.
yt-dlp can be used on an iPhone via a-shell (and possibly other shell apps).
