Why Use a Private PDF Viewer?
Many online viewers send your file to Google or Adobe servers for rendering. LovelyPDF renders entirely client-side using the open-source PDF.js library — the same engine that powers Firefox's built-in PDF viewer. Sensitive documents like legal contracts, medical reports, and financial statements stay completely private.
Frequently Asked Questions
Can I view password-protected PDFs?
Yes. You will be prompted for the password. It is used locally to unlock the document and never sent anywhere.
Is there a file size limit?
No server-side limit. Very large PDFs may be slow to load depending on your device. Pages render lazily as you scroll.
Can I print from the viewer?
Yes. Use your browser print function (Ctrl+P) while the PDF is open.
