Does not appear to be open-source, but was built from at least 90% open-source software.

And if you happen to have wasm or web workers disabled, you get an unhelpful "Processing 0/0 files…" message that just hangs forever.

Fair points.

It's built mostly on OSS and I’ll publish the remaining code with a proper license on GitHub this week.

The "0/0 files" thing ... that's something I hadn't ever even considered!

I'll replace the spinner with a plain message and a non-WASM note.

Thank you for your input!

Awesome. Thank you!
