FAQ
Is it safe to merge PDF files here?
Yes. Merging runs entirely in your browser with JavaScript. Your files are never sent to a server, so nothing is stored anywhere.
Can I merge more than two PDFs?
Yes. Add as many files as you need, put them in the desired order, then merge them all into one document.
Does merging reduce quality?
No. Pages are copied exactly as they are, so text, images and formatting stay identical to the original files.
