Merge reports, notes, or chapters into one PDF. Every page is copied in the file order you choose, without adding a watermark. Your files stay on your device: checking, merging, and creating the download all happen in your browser, without uploads or remote storage.
How to combine PDF files

- Drag files into order, or use Move up and Move down. Remove any files you do not need.
- Select Merge PDFs. When your document is ready, select Download PDF to save it.
A few things to know
Will my PDFs be uploaded?
No. PDF data never leaves your device. This tool has no upload endpoint and does not store your files remotely. Resetting the tool releases its local file references and download link.
Is merging PDFs free?
Yes. No account, subscription, or added watermark is required.
Can I merge protected or signed PDFs?
Encrypted PDFs, interactive forms, and portfolios are rejected. Export an unlocked, flattened copy using a trusted PDF application first. Merging creates a new document and cannot preserve digital signatures, bookmarks, or document-level attachments. Keep your originals.
Why might a PDF fail?
A file may be damaged, incomplete, or too complex for the browser. Export a fresh copy or try smaller groups. This tool copies pages; it does not repair PDFs, sanitize their contents, or certify PDF/A compliance.
