MIT license is generous. Good for you, and thanks!

The underlying PDFium is Apache 2.0 though, and it looks to me that the present project doesn’t currently comply with https://www.apache.org/licenses/LICENSE-2.0#redistribution for that dependency.

Good point, you’re right that PDFium is Apache 2.0. I’ve updated the project to comply with the redistribution requirements in this PR: https://github.com/embedpdf/embed-pdf-viewer/pull/80/files. Thanks for flagging it!

Thanks! I wanted to make it as easy as possible for people to use, tweak, and build on top of it, so MIT felt like the right choice.
