    react-pdf-highlighter is a React library that provides annotation experience for PDF documents on web. It is built on top of PDF.js by Mozilla. Text and rectangular highlights are supported. Highlight data format is independent of the viewport, making it suitable for saving on the server.

    Prior art

    react-pdf and react-pdfjs only provide React wrappers for PDF.js and do not have built-in annotation functionality.

    pdfjs-annotate does not provide text highlights out of the box.

    PDF.js provides only viewer:

    PDF.js is mainly written for reading PDF files, not editing them. Because of that we don't yet support adding any kind of annotations. We do however support rendering a number of annotation types for viewing.

    Wasn't this named react-pdf-annotator at some point?

    Yes, but people from asked me to rename, since they have a trademark for PDF Annotator.

    I'm trying the demo with my PDF and it is not loading!
