Merge PDF FAQ
How do I combine PDF files into one?
Add all the PDFs, use the arrow buttons to put them in order, then merge and download one PDF. The list order becomes the page order.
Is there a limit on how many PDFs I can merge?
There is no fixed limit. Very large files depend on your device’s memory, so on a phone it is best to merge a few files at a time.
Can I merge password-protected PDFs?
No. The owner needs to remove the password first, then the file can be merged.
My merged PDF is too large for the form. What now?
Run the merged file through Compress PDF to reduce its size.
Is the Merge PDF free?
Yes. The Merge PDF is completely free with no sign-up, no daily limit and no watermark.
Is it safe to use the Merge PDF with private files?
Yes. The Merge PDF runs entirely inside your web browser, so your files and text are never uploaded to any server.
Does the Merge PDF work on mobile?
Yes. It works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows and Mac.
