FAQ
Are my files uploaded anywhere?
No. The PDF is rendered entirely in your browser using JavaScript. It never leaves your device or touches a server.
Is there a page or file size limit?
No hard limit is enforced. Pages are rendered one at a time as you view them, so even large PDFs stay responsive.
Can I edit or download the PDF from here?
This tool is read-only. For edits, use one of LockerPDF's other tools (like Organize PDF or Add Watermark) and download the result from there.
Does this work on mobile?
Yes. The viewer works in any modern mobile or desktop browser, since all rendering happens locally.
