Frequently Asked Questions

Find Quick Answers

Is my PDF file uploaded to a server?

No, this tool works entirely client-side using JavaScript. Your PDF files are processed directly in your browser and never leave your device.

What PDF features are supported?

The viewer supports standard PDF features including text rendering, vector graphics, images, and basic annotations. It uses PDF.js which is the same technology used by Firefox and other modern browsers.

What is the maximum file size I can upload?

There's no specific limit, but very large PDFs may load slowly depending on your device's memory and processing power. For best performance, we recommend PDFs under 50MB.

Can I view password-protected PDFs?

No, this tool cannot open password-protected or encrypted PDF documents. You'll need to remove the password protection first using a different tool.
