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.
