react-pdf-highlighter


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.

  2. npm install

Prior art


[react-pdf](https://github.com/wojtekmaj/react-pdf) and
[react-pdfjs](https://github.com/erikras/react-pdfjs) only provide React
wrappers for PDF.js and do not have built-in annotation functionality.

[pdfjs-annotate](https://github.com/instructure/pdf-annotate.js/) does not
provide text highlights out of the box.

PDF.js provides only viewer:

FAQ


Can I get a new PDF with the highlights embedded into the document?

Take a look at https://pdf-lib.js.org.

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

Yes, but people from https://www.pdfannotator.com/ 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!
