- Click Merge PDFs and your combined file downloads right away.
Frequently asked questions
Are my PDFs uploaded to a server?
No. Merging happens entirely in your web browser, so your files never leave your device. That makes it safe for tax forms, contracts and other private documents.
Is there a file size or page limit?
There's no fixed limit. Because everything runs on your device, very large files (hundreds of MB) depend on your computer's memory and may be slow on phones.
How do I change the order?
Use the up and down arrows next to each file. The merged PDF follows the list from top to bottom.
Can I merge password-protected PDFs?
Not yet. Remove the password first (for example by opening it and using Print to PDF), then merge.
Will the merged PDF keep quality and links?
Yes. Pages are copied as they are, without recompressing, so text stays sharp and searchable. Bookmarks and form fields from the original files may not carry over.
