How it works
Drop your files, reorder them by drag and drop, click Merge: the combined PDF downloads immediately. Unlike typical online services, nothing is uploaded to a server — the merge is computed by your browser, which makes it suitable for contracts, payslips and medical records.
FAQ
Is there a size or file-count limit?
Since everything is processed in your browser, the limit is your device's memory. We warn above 100 MB per file or 500 pages in total, thresholds beyond which a modest device may struggle; you can carry on past the warning, and cancel at any time.
Are bookmarks and forms preserved?
Pages, their content and rotation are preserved exactly. Bookmarks from the source documents are not merged in this version.
Can I merge password-protected PDFs?
Only if they open without a password. An encrypted PDF is detected and refused with a clear message rather than mishandled: unlock it in your PDF reader first.
