What Zaya is
Zaya is a free, open-source PDF reader delivered as a self-hosted or web progressive web app. It displays documents with realistic 3D page turns, while also offering single- or double-page views and a CSS fallback for WebGL displays. PDFs can come from a URL, a local file, or a deployment’s configured default. Full-text search highlights matches, and browser-based Arabic or English OCR can recognize scanned pages without uploading the recognized text. Readers get selectable text, thumbnails, outlines, bookmarks, local notes, quotes, page-range printing, and more than 50 themes. The interface supports English, Arabic, and right-to-left reading. Its media player handles YouTube videos, playlists, and local audio. Zaya can work offline after one visit and open stored PDFs without a connection. Quotes and preferences can be exported to JSON, imported elsewhere, or shared through setting-aware links. Remote PDFs require CORS enabled on their server.
