Frequently Asked Questions
Everything you need to know about our browser-first architecture, privacy guarantees, and tool capabilities.
Are my uploaded PDF files and confidential documents safe?
Yes. Unlike traditional cloud converters, WeLovePDF operates on a browser-first zero-upload architecture. Core tools (Merge, Split, Compress, Rotate, Protect, etc.) run in-memory inside your local web browser sandbox using WebAssembly. Your files never touch external servers or third-party cloud storage.
Is WeLovePDF really 100% free with no limits?
Yes, completely free. There are no subscription tiers, no page limits, no daily file count caps, and no forced account registrations or credit cards required.
Does WeLovePDF work offline without an internet connection?
Yes. Once the web application is loaded in your browser tab, all client-side WebAssembly tools function entirely offline. You can disconnect your internet or enable airplane mode and continue processing files.
What is the maximum file size supported?
We support documents up to 200MB per processing session for browser-side utilities. Because files are processed directly in your device RAM, performance depends on your local device memory.
How does the Protect PDF encryption work?
Protect PDF locks your document using standard AES-128 / RC4 encryption supported by PDF-lib. The password is applied locally in your browser memory and is never transmitted over the internet.
How does the Redact PDF tool work?
The Redact PDF tool applies a visual black overlay over specified rectangular areas. For legal proceedings, court submissions, or classified information where underlying vector streams must be permanently stripped, use certified professional redaction software.
How does WeLovePDF differ from iLovePDF or Smallpdf?
Traditional converters upload your files to remote cloud servers for processing, which introduces data exposure risks for sensitive contracts and medical records. WeLovePDF processes files client-side in your own browser, guaranteeing absolute data custody.
Which devices and web browsers are supported?
WeLovePDF is fully compatible with modern browsers supporting WebAssembly: Google Chrome, Apple Safari (desktop & iOS), Mozilla Firefox, Microsoft Edge, and mobile browsers on Android and iPhone.
Do you train AI models or log content from my files?
No. We never log, store, index, sell, or train AI models on user document content. Temporary memory buffers are automatically wiped when you close or refresh your browser tab.
Who develops and maintains WeLovePDF?
WeLovePDF was created and is actively maintained by Nilesh Verma, an independent full-stack developer based in Bettiah, Bihar, India, dedicated to building private browser-first utilities.
