Questions & answers

Everything you might need to know before using the tool.

How many PDFs can I merge at once?+

There is no limit on the number of files. You can merge 2, 10, or 50+ PDFs at once. For very large batches (50+ files), processing may take a few extra seconds.

Will the page numbers be continuous after merging?+

The merged PDF will have continuous pages in the order you specified. If you need custom page numbering, add header/footer page numbers after merging using our Add Header/Footer tool.

Is it safe to merge confidential PDFs online?+

Yes. All processing happens in your browser using pdf-lib. Your documents never leave your device and are never uploaded to any server.

Your files are private

All processing runs locally in your browser using JavaScript. Your files are never transmitted to any server, stored, or shared. Close the tab and they're gone.
