How to use Merge PDF
- Select two or more PDFs.
- Use Up and Down beside each file to set the order.
- Choose Merge PDFs, then download the combined document.
What happens to your file?
All pages from the first file come first, followed by the next file in the list. Remove an unwanted file before running the merge. You can add more PDFs by selecting files again.
Before you start
Combined output is limited to 500 pages. Interactive forms are rejected to avoid losing field values. Bookmarks and document-level features may not carry over.
Use an unsigned copy of important documents. Editing a PDF can invalidate digital signatures. Files are kept only in this tab while you work; Reset clears the selection and generated downloads. On smaller devices, use fewer or smaller files.
Are my files uploaded?
No. Processing uses this browser. The tool does not send your file contents to Cordell Digital or a conversion service.
Why did my file fail?
Check its type and size, then try a smaller, valid file. PDFs must not be password protected. Image inputs must have at most 24 million pixels. Your device also needs enough free memory for processing.
