As Heba answered above, https://www.almaany.com/ is really good. However, if you want a traditional dictionary, I highly recommend al-mawrid, which includes Hans Wer's Arabic-English, Lisan al-Arab and much more: https://ejtaal.net/aa/
There's a way to download that and use it offline. It's much better if you need the etymology of certain words and the translation of less common words are more accurate.
