Hi there. Avogadro is free and can help you ;)

Further alternatives:

• PyMOL, has GUI (whether Schrodinger's or the OpenSource repository)
• MDAnalysis, a python package, you can load the .pdb and save it as .mol2:

MDAnalysis.Universe('file.pdb').atoms.write('file.mol2')

• Antechamber (from AmberTools, can be installed with Conda):

antechamber -i filename.pdb -fi pdb -o filename.mol2 -fo mol2
