Limits and behavior
Page content is copied. Document-level bookmarks, signatures and interactive form structure are not merged. Local processing. Maximum 10 MB per file, 25 MB total and 100 PDF pages. Encrypted PDFs require the separate known-password decryption tool. Digitally signed input may lose signature validity after any modification; preserve your original. Unsupported or malformed files produce an error. Cancellation stops active PDF renders and discards stale results; a synchronous library step finishes before the browser can handle cancellation.
Merge PDF files into one document
Combine multiple PDF documents into a single file in the order you choose. This online PDF merger helps join reports, scanned pages, attachments and other PDFs without manually recreating the documents.
Does merging PDFs change the page order?
The output follows the file order selected in the tool. Confirm the final page sequence before sharing a combined document.
