Questions
How do page ranges work?
Leave the box empty to take the whole file. Otherwise type page numbers and ranges separated by commas, for example 1-3, 7, 10-12. Pages are taken in the order you write them, so 3,1 puts page 3 before page 1. The box turns red if a number falls outside the file.
Are my PDFs uploaded?
No. Merging happens in this page with pdf-lib compiled to JavaScript. Your files are read into memory, combined, and handed back as a download. Nothing is transmitted, which is the point for contracts, statements and medical records.
Is there a limit on file size or page count?
There is no artificial cap, unlike most free sites which stop at 20 or 50 pages. The practical limit is your device memory, since the whole job runs locally. Very large merges are slower on a phone than on a laptop.
Why will my file not open?
Password-protected PDFs cannot be read until they are unlocked, and a small number of damaged files cannot be parsed at all. The row will show the error rather than failing silently, and you can remove it and merge the rest.
Are bookmarks, forms and links preserved?
Page content, images and text are copied faithfully. Interactive extras such as form fields, bookmarks and annotations are not always carried across, because they belong to the document rather than to a page. If you need a form to keep working, merge with care and check the result.
