Combine multiple PDFs into a single file.
Join several PDF files into one document without changing the page content, useful when separate files need to become one submission or archive.
Best for: Combining statements, application documents, invoices, chapters or scanned sections into a single ordered PDF.
Merging copies pages from each source PDF into a new PDF. The important decision is page order: the tool cannot know whether “document 2” belongs before or after “document 1.”
Loads each selected PDF with pdf-lib, copies all pages in file order into a new PDF, and downloads the combined document. No page content is interpreted or rewritten beyond the PDF library save step.
Use specialist software for encrypted, digitally signed or malformed PDFs that cannot be loaded safely in-browser.
This section describes the implementation shipped with My Tools HQ. Verify important outputs before relying on them.

Page content is copied into a new PDF rather than intentionally rasterized, so ordinary pages should retain their source quality.
Yes. A single PDF can contain pages with different dimensions, though the visual result may look inconsistent.
Usually merge first, check the document, then compress the final file if you need to hit a size limit.
A repeatable checklist for combining statements, applications and scanned documents without missing or duplicating pages.
