How to merge PDFs online privately
Combine two or more PDF files into a single document without uploading them to a server. DropToSolve runs pdf-lib in your browser, so contracts, IDs, and invoices stay on your device.
How to use it
- Drop or select the PDF files you want to combine.
- Reorder with Up / Down if the sequence matters.
- Click Merge and download the combined PDF.
When it helps
Useful when you need one attachment for email, a complete application pack, or a single archive of scanned pages.
FAQ
- Is there a file size or page limit?
- Only what your device memory can handle. Very large PDFs may be slow on phones; desktop browsers usually handle bigger batches.
- Are my files uploaded?
- No. Processing happens locally in your browser. We never receive your documents.
- Can I merge password-protected PDFs?
- We try to open many encrypted PDFs without asking for a password. If merge fails or pages look incomplete, unlock the PDF in another app first, then try again.
- Does merge change the original files?
- No. You download a new file. Your originals stay unchanged on disk.
- Does it work on mobile?
- Yes in modern mobile browsers, though large merges are more comfortable on a computer.
