Frequently Asked Questions

How does PDF merging work?

Merging happens entirely in your browser using pdf-lib. Your files are never uploaded to any server.

Can I reorder the pages before merging?

Yes — drag the file rows to reorder them. Pages from each file are included in the order the files appear in the list.

Is there a limit on file size or number of PDFs?

There is no enforced limit, but very large files (50 MB+) may take longer. Browser memory limits apply.

Will formatting and fonts be preserved?

Yes. The merger copies pages as-is, preserving all fonts, images, and layout exactly as they appear in the originals.
