Optional: type a page range on any PDF card, such as 1-3, 7, to include only those pages.

Frequently asked questions
Are my files uploaded to a server?
No. Merging runs in your browser with JavaScript, so your PDFs never leave your device.
Is there a limit on file size or the number of files?
There is no fixed limit. The practical ceiling is your device's memory; hundreds of pages merge comfortably on a normal laptop.
Can I merge password-protected PDFs?
Yes, if you know the password. Locked files show a password field on their card. The merged file itself has no password; use Protect PDF afterwards if you need one.
Can I add JPG or PNG images?
Yes, along with WebP and HEIC. Each image becomes its own page in the position you place it. JPG and PNG are embedded without recompression; other formats are converted first.
How do I start each document on a new sheet when printing double-sided?
Turn on Pad to even pages. A blank page is added after any file with an odd page count.
Does merging lower the quality or keep bookmarks?
Pages are copied unchanged, so text stays sharp and selectable. Bookmarks (the outline) of the source files are not carried into the merged PDF.
