As answered by people managing ImageOptim and 70aitools.
70aitools's answer:
All 59 tools run directly in your browser — files never leave your device. No signup, no watermarks, no usage limits, and everything is free. One site covers images, PDFs, documents, text, code and everyday calculations, so you don't have to jump between separate single-purpose sites.
70aitools's answer:
Most competing tools upload your files to a server, require an account, or cap free usage. 70aitools processes files client-side (faster and more private), is completely free with no signup, and bundles 59 tools in one place.

70aitools's answer:
Everyday users and professionals who occasionally need quick file tasks — compressing images, converting or merging PDFs, cleaning up text or code — and want it done instantly without installing software or creating an account.
