PDF Unlimerge

PDF Unlimerge is a free, browser-based toolkit: merge, split, compress, sign, redact, and convert PDFs with no account needed. It also does things no other PDF site does - free WCAG/ADA accessibility remediation, a forensic tamper-detection tool (PDF Diego), a real-time air quality and hazard checker (Are You Safe?), and Color Sweeper, a live 1v1 video game that pairs you with a random stranger to break the ice. One site, way more range than the name suggests.
