About PDF
PDF — Portable Document Format. PDF keeps a document looking the same on every device, with fixed pages, fonts and layout. That makes it ideal for sharing and printing, but hard to edit.
FAQ
5Are my files uploaded anywhere?
No. The conversion runs in your browser using your own device’s processor. Your files are never sent to a server, so nobody — including us — can see them. You can even disconnect from the internet after the page loads.
Will I lose quality?
Merging copies the pages exactly as they are, so nothing is re-compressed or lost.
Is there a file size or daily limit?
No limits, and no sign-up. Because nothing is uploaded, we don’t pay for your conversions and have no reason to cap them. Very large files are limited only by your device’s memory.
Can I merge password-protected PDFs?
PDFs that only restrict editing or printing usually merge fine. PDFs that need a password to open must be unlocked first.
Does it work on iPhone and Android?
Yes. It works in any modern browser — Safari, Chrome, Firefox or Edge — on phones, tablets and computers. Older or low-memory phones may be slower with very large files.
