Frequently Asked Questions
How many PDF files can I merge at once?↓
There is no hard limit. You can merge as many PDFs as your browser memory supports. Most users merge 2-20 files without issues.
Can I reorder pages before merging?↓
Yes. Drag and drop files to change the merge order. The final PDF will contain pages in the order you arranged the files.
Is merging PDFs free and private?↓
Yes. Merging uses pdf-lib running in your browser. Files never leave your device. No signup required and no limits on file size or document count.
Can I merge password-protected PDFs?↓
Password-protected PDFs need to be unlocked before merging. Remove the password protection first then merge the unlocked files.
