Frequently asked questions
- Yes — drag the file cards into any order, and open a file to reorder its individual pages before merging.
- No fixed limit. Merging happens in your browser, so the practical ceiling is your available RAM — typically several hundred megabytes of PDFs.
- Never. Merge PDF runs 100% locally; the files are never transmitted to any server.
