Merge PDF files online.
Combine two or more PDFs into one clean document in the order you select.
Combine multiple PDFs into one document
Use the SizeFix PDF merger when separate pages, forms, reports or scanned documents need to be submitted as one file. Select the PDFs in the order you want them to appear and download one combined document.
The merge happens in the browser, which keeps the workflow simple and avoids sending your files to a SizeFix processing server.
Merge PDF FAQs
Can I merge more than two PDFs?
Yes. Select two or more PDF files and SizeFix combines them in the order selected.
Will the page quality change?
The merge tool copies pages into a new PDF rather than rasterising them, so page content is preserved.
