I spent hours online to find appropriate tools for YouTube video to FLAC conversion, but only 2 of them allow users to directly download and convert a YouTube video to FLAC. Others don’t support exporting the YouTube videos as FLAC format, most of them just support exporting as MP4, MP3, and WEBM.

Convert2mp3 is an online video converter and it does allow users to convert an online YouTube video to FLAC, however, it doesn’t work at all, no matter which output format you choose for the YouTube, it just allows users to save as MP3.
As you can find in the following screenshot, I input the YouTube URL and choose output as FLAC. After clicking the Convert button, the program just indicated that the MP3 file was ready for download. It doesn’t work out at all.
3. Onlinevideoconverter fails to convert YouTube to FLAC
Onlinevideoconverter is another online free tool claiming to convert YouTube file to FLAC format directly. Yet, in all my tests, it failed to convert my YouTube videos.
As you can see, I follow the on-page instructions to input YouTube URL and choose output as FLAC.
However, no matter how many times I tried or which YouTube URL I input, it just failed to convert the videos. Anyway, you can have a try, maybe the failure is only caused by specific YouTube videos.

FLAC (Free Lossless Audio Codec) and MP3 (MPEG Audio Layer-3) both work as a popular audio format to play music on different devices. But they are different in 4 ways:
So, it is hard to tell if FLAC is better than MP3, it depends on what’s your priority and which device you are using to play the audios.
The short answer is No. When you upload video to YouTube, it will automatically compress the audio, and quality will reduced during the peocess. often they will compress the audio to 192kbps. in other words, lossy. If you convert the lossy YouTube audio to FLAC, the audio quality will not be improved. and converting to FLAC is not worthy, it will just get a larger size file with the same lossy quality.
As for the highest YouTube audio quality, AAC is the default audio format for streaming services like YouTube. The best quality will come it you save the video as AAC.
