About Priya LifePDF
A free, fully browser-based PDF toolkit built specifically for pharmaceutical, biotech, and life science professionals in Ireland and the EU. 132+ specialist tools. Zero file uploads. Zero subscriptions.
Who We Are
Priya Life Science is an Irish pharmaceutical services and consulting company operating from Dublin, Ireland. Our team works daily alongside QA managers, regulatory affairs specialists, validation engineers, and batch record coordinators across the Irish and EU pharmaceutical and medical device industries.
We provide pharmaceutical consulting, documentation services, GMP training, and regulatory support to companies operating under HPRA (Health Products Regulatory Authority Ireland), EMA, FDA, and EU GMP Annex 1 frameworks.
Priya LifePDF was developed internally by the Priya Life Science technical team — not as a commercial product, but as a community tool for the life science sector, offered permanently free of charge.
Why We Built Priya LifePDF
In our day-to-day pharmaceutical consulting work, our team constantly processes controlled documents — Standard Operating Procedures, Batch Manufacturing Records, Validation Protocols, HPRA regulatory submissions, audit reports, and Quality Management System documentation.
Every time we needed to apply a GMP status stamp (APPROVED, DRAFT, CONTROLLED COPY, SUPERSEDED), compress a validation package, or merge a batch dossier, the available tools required uploading confidential documents to a third-party server — an unacceptable risk under GDPR and EU GMP data integrity requirements.
We searched for a browser-based, privacy-first alternative built for life science workflows. Nothing adequate existed. So we built it ourselves.
Priya LifePDF runs entirely within your browser using WebAssembly (WASM) technology — the same approach used in secure banking and military-grade software. Your PDF files are loaded into your browser's local memory, processed at native speed, and never transmitted to any server. Not even our own.
We made the tool completely free because we believe that compliance tools should be accessible to every QA professional, small CMO, CRO, or independent consultant — not just companies that can afford enterprise software licences.
There is no premium tier, no subscription, no hidden fee. The full platform — all 132+ tools — is permanently free, with no account required.

How It Works — The Technology
Priya LifePDF is a fully static web application. There is no backend server processing your documents. Every tool runs inside your browser tab using a combination of modern browser APIs.
WebAssembly (WASM)
PDF transformations are compiled from native C++ and Rust libraries (LibreOffice, MuPDF, QPDF) into WASM binaries that run at near-native CPU speed inside your browser. No server. No cloud.
Web Workers
Heavy processing runs on a background thread so your browser tab never freezes. You can interact with the page while large PDFs are being processed in parallel.
PDF.js + pdf-lib
Industry-standard open source PDF rendering and manipulation libraries used by Firefox, Adobe, and thousands of enterprise applications worldwide.
Next.js Static Export
The entire site is exported as static HTML/CSS/JS and hosted on a standard web server. No Node.js server, no API routes, no dynamic backend to be breached.
Browser Sandbox
All file data lives in your browser tab's isolated memory sandbox. When you close the tab, all data is erased. Nothing persists to disk or cloud storage.
Service Worker Cache
WASM binaries are cached locally after first load. Subsequent visits load instantly and all tools function even without an internet connection.
