How to Merge PDFs
Merge multiple PDF files into one document in a few steps using PDFCustom.
Before you start
Open the Merge PDF tool and gather the files you want to combine into one final document.
You can use PDFCustom in guest mode for quick one-off jobs, or sign in if you want to save your history and settings.
Merge your files
Upload two or more PDF files, reorder them if needed, and review the queue before you process the job.
When the order looks right, start processing and wait for the merged file to appear in the results panel.
Download the result
Download the merged PDF once processing is complete.
