Wait, the optimization does not leave the browser. There isn’t any need for a web server.

If this can be used as an offline PWA, it doesn’t even need to be ‘self-hosted’, except for keeping it up to date.

Edited: removed reference to “device”, to avoid confusion.

While I appreciate the sentiment, I do think that despite being well-intentioned this could just contribute to today’s digital illiteracy. It also downplays the app’s privacy, I almost dismissed it as a cloud service the moment I saw that.

Perhaps you could use “open” and “save”, which is widely understood and probably more appropriate.

That said, the app is a great initiative, and I’ll certainly give it a look once I get in front of a computer, and probably recommend it to students.

I’m confused, isn’t this running locally? Why are you using the words “upload” and “download”?
