Local PDF Tools – Powered by WebAssembly

For something like this, how do we know that the files are not sent to a server? Am I just trusting the web app? Is there any way to be sure other than having and reading the source?

You can load the website and then disable the network, either by turning off the connection in your OS or via File -> Work Offline in Firefox.

I just did this and it worked.

Good tip. Though it would be nice to be able to disable network activity per tab.

Open dev tool and monitor network?

For someone who knows that these tools exists, yes this is a way.

For an ordinary user, the only 'easy' way a user can verify the claimed behaviour is to literally go offline.

Browsers do not currently have badge to verify that the app is not sending any data. I'm thinking how we were brought to trust the padlock icon browsers display for TLS supporting sites.

Something like that would be great, seeing that you can do more and more with wasm locally it would be really useful

Disconnect from the network and try it? Or disconnect from the network always when using this?
