Hi @Ayakashi97 I probably forgot to include in my [Guide](https://discuss.elastic.co/t/custom-logo-kibana-7-9-2-guide/250814), that the smaller the base64 image file, the easier it will be for Kibana to process the file you are modifying. I recommend a size no larger than 100px. So first, reduce the original image file to 100px, then convert it to base64 and you will see that the generated code is much smaller. Pay special attention to the portion of code you need to remove from file `kibana/src/core/target/public/core.entry.js`, as if is not done right, it might cause to load a blank page.

And for the command `npx`, just install package `npm` first, as `npx` is part of it 😉

I am also waiting for the official way to customize the interface, so we do not have the need of these hacky solutions 😅

Cheers!
