Merge PDF FAQ
Is this Merge PDF tool free?
Yes. You can combine PDF files in your browser and download the merged PDF.
Are my PDF files uploaded?
The merge work is designed to happen in your browser using a client-side PDF library. Avoid using any online tool for highly confidential files unless it is approved for that data.
Can I change the order before merging?
Yes. Use the up and down buttons beside each file to arrange the final PDF order.
Why does a large PDF fail?
Very large or encrypted PDF files can exceed browser memory limits or may not be readable by the client-side PDF library.
