FAQ

Q. How many files can I merge?

There's no fixed limit. You can merge as many as your browser's memory allows.

Q. Can I change the order later?

After adding your files, you can rearrange them freely with the arrows until you click the merge button.

Q. Can I merge only some of the pages?

Files are merged whole. To keep only the pages you need, merge first, then delete or pick pages in Organize PDF pages.

Q. Can I merge password-protected PDFs?

Not while they're locked. Merging locked files leaves blank or broken pages, so if a locked file is included, we won't merge and will let you know. Unlock it first with Remove PDF password, then add it again. If you know the password, it only takes a moment.
