Frequently Asked Questions
Is it safe to edit PDFs online?
Yes! Our PDF editor processes files entirely in your browser. Your documents never leave your device or get uploaded to any server, ensuring complete privacy and security.
Can I edit scanned PDFs?
Scanned PDFs are essentially images. While you can add annotations, highlights, and signatures on top of them, editing the underlying text requires OCR (Optical Character Recognition) technology, which is best handled by specialized OCR tools first.
What file size limits apply?
There are no hard file size limits. The only constraint is your device's memory. Most PDFs under 100MB edit smoothly on modern computers and smartphones.
Can I edit PDFs on mobile?
Absolutely! Our PDF editor is fully responsive and works on all devices including smartphones and tablets. The touch interface supports pinch-to-zoom for easy editing on smaller screens.
