React PDF Kit is a drop-in React component for products that need to show PDFs properly: text selection, form filling, thumbnails and a UI that follows the host app's styling. It renders text, canvas and AcroForm layers rather than flattened images, which is what makes search, highlighting and accessibility work inside the document.

More than 20 features out of the box, including virtual scroll, lazy loading, search with highlighting, print, download, page and thumbnail navigation, and full screen.
An annotation plugin adds highlights, strikethrough, underline, freehand draw, text and comment threads, shapes, stamps and images on top of the viewer.
Perpetual licence with one year of free updates and support, a 50% renewal discount, 14-day money back, Developer and Organization tiers, and per-domain or wildcard activation.

Pricing is quoted in US dollars through Stripe, and licenses cover unlimited websites. The Black Friday promotion takes 50% off either tier.
