One of my favorite online free hash crackers: https://crackstation.net/

Works with UNSALTED hashes ONLY! Just enter up to 10 hashes, a captcha, and hit "Crack Hashes". There is also the option to download their wordlist used for cracking, for FREE! (There is an option for donations) You can even download a program (in PHP and C) which implements the list to crack hashes.
