Frequently Asked Questions
Common questions about merging PDF files online.
Are my PDFs uploaded to a server?
No. All merging happens entirely in your browser using pdf-lib. Your files never leave your device and no data is sent to any server.
Can I reorder the PDFs before merging?
Yes. After uploading, you can drag and drop the files into any order. The merged PDF will follow exactly the sequence you set.
Will text and links in my PDFs still work after merging?
Yes. Text, clickable links, images, and page layout are preserved from each source PDF. The merged output is a standard PDF compatible with all viewers.
Is there a limit on how many PDFs I can merge?
There is no artificial limit. You can merge as many PDFs as your device's memory allows. Large files on lower-memory devices may be slow, but there is no paywall or cap enforced by this tool.
