Frequently asked questions
How do I merge PDF files?
Drop two or more PDFs onto the merge tool, reorder them if you want, and click Merge. The combined PDF downloads instantly.
Is there a file size limit when merging PDFs?
PaperKit runs in your browser, so the only practical limit is your device memory. Most users merge dozens of PDFs without issues.
Are merged PDFs uploaded to a server?
No. The merge happens 100% in your browser, so your files never leave your device.
