Frequently Asked Questions
Can I change the order of the PDFs I'm merging?
Yes. After uploading, drag and drop the files into any order — the merged PDF's page order follows your arrangement.
How many PDF files can I merge at once?
You can merge up to 30 PDF files at once. The total size is limited by your browser's available memory.
Does merging reduce quality?
No. Merging doesn't re-render page content — the original text, image, and vector quality is preserved exactly.
Can I merge password-protected PDFs?
You'll need to remove the password first with the Remove PDF Password tool before adding it to the merge.
