makes it difficult to verify that it runs locally. unobfuscated source is not available. important actions, like open a PDF, save edited PDF, will be stuck or error if you cut the internet after opening the site and only unstuck after you reenable internet. I get it's probably for speed

anyway, if you save the page in Chrome and serve it on a local server, it works even with internet disabled, so there's that.

Thanks for pointing this out. You’re right - some assets are currently loaded at runtime, which can cause actions to hang if the internet is cut mid-session. All PDF processing itself happens locally in the browser, and as you noticed, serving the page locally works fully offline. Improving offline behavior and making this easier to verify is on the roadmap
