Do you know this site:
https://convertio.co/de/jpg-svg/
You can convert there any image file for example in svg. When you have a clean image the svg image concertion turn out very high quality.
I know vektor art can be much more work then a normal drawing so you should definitly chack this out ;)
Thanks I didn't know the webiste and it can be useful in some cases. There's a converter in Illustrator too. But at the moment, when you need a really precise work it's still the best to do it by your own. It takes time but it's the best option in case you need a clean work.
