I'm currently embedding PDFs using a simple iframe.<p>I can't use the Adobe PDF Embed API due to the legal requirements around our customer documents.<p>I'm looking into what the best options are regarding embedding a PDF with the ability to annotate and add highlighting and such (specifically highlighting excerpts we extract from the document).<p>I've looked into PDF.js, but it seems like it might be difficult to maintain. Apryse seems too enterprise focused for a startup. Foxit or PSPDFKit potentially?<p>Would love any recommendations or advice!
