Frequently asked questions
How do I merge PDF files?
Select two or more PDF files and use the merge action. Their pages are combined in the order shown by the tool.
Does merging change the contents of my PDFs?
The tool combines pages into a new PDF. It does not edit page text or guarantee preservation of interactive forms, signatures or unusual document features.
Are PDF files uploaded?
No. Merging is performed locally in your browser; the files are not sent to ihatecalc.
