Is there a free service which covers the same features as Adobe acrobat?

acrobat does a ton of stuff. there are lots of tools that do some of the things it can do, but I don't you're going to find something that's a complete replacement for free

I can do all of this offline for free already with Acrobat or Preview.app on macOS.

Why?

"uses WebAssembly" - forgive me but what? How do I know my PDF isn't going to Russia? or China? I mean, I could wireshark it but I'd like to know more about what's in the webassembly. PDF's are sensitive to some organizations. As already stated, some orgs even block online pdf tools for obvious reasons.

I'm interested in this but I would be even more so if there was source so I can audit. Since it's running locally in my browser anyway.

Is WebAssembly less trustworthy than minified/obfuscated JavaScript?

WebAssembly has no implicit access to browser APIs so I wouldn't think so.

You can check the network tab. WebAssembly doesn't have magic powers like ActiveX or something like that.

So most common online pdf tools like smallpdf.com and ilovepdf.com are blocked on office networks for obvious reasons. Can we save this page as .html file on a local folder and run it from browser -- never triggering the firewall / websense blockers etc?
