UAIP Yet Another PDF Editor for WordPress

A free WordPress plugin that embeds PDFs with a modern, accessible viewer and lets you and your visitors annotate, fill in and sign PDFs right in the browser.

• Viewer: continuous scroll, search, clickable links, text selection, thumbnails and bookmarks, jump to page, download, print, full screen, lazy loading, keyboard and screen-reader support. All free, no premium version.
• Flipbook: the same PDF as a book with turning pages (StPageFlip), two-page spreads or single pages on phones, cover page, right-to-left books, lightbox from a cover, thumbnail strip. [yape_flipbook id="123"] or the PDF Flipbook block.
• Editor (in progress): annotate, fill forms, sign, page tools and redaction, powered by PDFium compiled to WebAssembly and loaded only when someone opens it.

Build

Requirements: Node 22.13+ (or 24) and pnpm. The engine also needs Rust with the wasm32-unknown-unknown target.

pnpm install
pnpm build        # viewer + block + pdf.js assets into plugin/build/
pnpm zip          # dist/uaip-yet-another-pdf-editor.zip, ready for WordPress

Local WordPress

pnpm build
cd dev && docker compose up -d && sh setup.sh

The site runs at http://localhost:8095 on WordPress 7.1.3 (user admin, password generated into the git-ignored dev/.data/admin-password.txt) and mounts plugin/ as an active plugin. setup.sh generates a sample PDF and a "Viewer test" page. To test other plugins alongside, mount them in a git-ignored dev/docker-compose.override.yml.

Checks before a release: pnpm check (TypeScript), php -l on PHP 7.4, and Plugin Check (docker compose run --rm cli wp plugin check uaip-yet-another-pdf-editor).
