When you need to combine PDFs
Invoices scanned page by page, a report split across multiple exports, or a contract you need to assemble from separate sections — merging PDFs is a common daily task. This tool handles it entirely in the browser so sensitive documents never touch an external server.
Frequently asked questions
There is no hard limit. However, very large PDFs (hundreds of pages each) may take a few seconds to process since everything runs in your browser without any server acceleration.
The tool attempts to open password-protected PDFs but currently does not support entering passwords. Remove the password protection first using Adobe Acrobat or another tool, then merge.
No. Everything runs locally in your browser using pdf-lib. Your documents never leave your device.
Page content, text, images, and vector graphics are preserved. Bookmarks (outlines) and interactive form fields may not be carried over in all cases, as they require special handling in the merge process.
