Google Docs-style characters sheets created by Mattie Casper and updated by me can be found here. They aren’t quite as nice looking as fillable PDFs but may be easier to use for some online games. Mattie’s original sheets didn’t include a few classes that didn’t exist at the time (Druid, Barbarian, Immolator) and had some older rules/stats/spells in place. These are now current to 2017 DW standards.
