Questions and practical tips

Will the pages be resized?

This merge operation preserves original page dimensions, so a combined PDF can contain pages of different sizes.

Should I retain the original PDFs?

Yes. Keep the source documents and check page order, page count and any interactive features in the combined result before sharing it.

Processing and file safety

This tool processes files in your browser. Loading the page, libraries or AI models can still require network connections. Keep a copy of your original files and check the downloaded result before deleting them. Large files may require more memory and processing time than your device can provide.
