Frequently asked questions
Is there a file size limit?
Up to 100 MB per file and 50 files per merge. Very large merges depend on your device memory; if the browser runs out, split the job into smaller batches.
Does merging reduce quality?
No. Pages are copied as-is. Text stays selectable, images keep their resolution, and vector graphics remain sharp.
Can I merge password-protected PDFs?
Not directly. Remove the password in the app that created the PDF (or with the owner's permission) and try again.
Are bookmarks and form fields kept?
Page content, links and annotations are kept. Document-level bookmarks (outlines) and interactive form fields are not carried over to the merged file.
Are my PDFs uploaded?
No. The merge uses the pdf-lib library running in your browser. Nothing is sent to a server.
