Does the order of files matter?
Yes. The final PDF uses the same order shown in the grid. Move a contract cover page, invoice or appendix before clicking Merge PDFs if it should appear earlier in the document.

Merge PDF
Add at least two PDF files, arrange them in the queue and export one merged document.
Merge contracts, invoices and PDF chapters into one file
Use Merge PDF when several documents need to travel as one clean file: scanned pages of a contract, monthly invoices for accounting, signed attachments, reports from different teams or chapters of a larger document. Instead of sending a folder of separate PDFs, you can combine them into one document in the exact order you choose.
The file cards show previews of the first page, so it is easier to spot the right order before exporting. Drag the cards to reorder them, add more PDFs if something is missing, and then create one merged file that is simpler to email, upload to a portal, archive or forward for approval.
How to merge PDF files
- 1Add two or more PDFsClick Choose files or drag PDF documents into the upload area. You can add scans, invoices, contracts, reports or other PDF files in one queue.
- 2Set the file orderDrag the PDF cards in the grid until the order matches the final document. The merged PDF follows this queue from first file to last file.
- 3Create the combined PDFClick Merge PDFs and download a single file that contains all selected documents in the chosen order.
Private merging without uploading files
The PDFs are combined inside your browser. ClickPDF does not upload contracts, invoices or internal documents to a server for merging. Keep the tab open until the final file is downloaded, because the temporary result exists only in the current browser session.
Merge PDF questions
Can I merge PDFs from different sources?
Yes. You can combine scans, exported invoices, reports, forms and other PDF files as long as the browser can read them as valid PDFs.
Is there a limit to how many PDFs I can combine?
There is no fixed server-side limit because processing happens locally. Very large files or long queues depend on your device memory and browser performance.
Will merging change the page quality?
No intentional quality reduction is applied. Pages are copied into one document, so scans and text should keep their original appearance unless the source file is damaged or unsupported.
