PDF Merge
Combine multiple PDFs into a single file — reorder, then download.

Frequently asked questions
How many PDFs can I merge?
There is no hard limit. Browser memory is the bound; in practice 20-50 typical PDFs work fine on a modern laptop.
Will form fields, links, and bookmarks survive?
Form fields and links survive at the page level. Outline bookmarks from individual PDFs are not preserved in the merged file because pdf-lib treats them as document-level.
Are the files uploaded anywhere?
No. Merging happens entirely in your browser via pdf-lib.
Can I merge only specific pages?
Not yet. This tool merges every page from every input PDF in order. For page-level selection, use the PDF Optimizer first to drop unwanted pages, then merge.
