A native, fast, offline PDF viewer with search and zoom capabilities.
Historically, desktop PDF readers like Adobe Acrobat were massive vectors for malware. Because PDFs can contain interactive JavaScript and complex font definitions, hackers would embed malicious payloads or exploit buffer overflows in the C++ font rendering engine to take over users' computers.
When you view a PDF in our tool (which is powered by the Mozilla PDF.js engine), the document is parsed and rendered entirely within the rigid V8 JavaScript engine of your browser.
This means the PDF parsing engine runs inside the browser's heavily fortified security sandbox.
The PDF engine does not have direct access to your computer's filesystem, memory architecture, or operating system APIs. It is only permitted to draw geometric shapes and pixels onto an HTML5 <canvas> element.
Even if a PDF contains a malicious exploit specifically designed to crash Adobe Acrobat or run a ransomware payload, our sandboxed browser viewer will safely ignore it, rendering it completely harmless.
Why is viewing a PDF in a modern browser generally safer than using legacy desktop software?
