Frequently asked questions
Quick answers about merging PDFs with ConvertKit Lite.
Are my PDFs uploaded to a server?
No. Merging runs in your browser, so your files are not uploaded anywhere.
How do I change the order of the files?
Drag any file in the list up or down. The numbers update, and the PDFs are merged in that order.
How many files can I merge?
There is no limit on our side. Very large or very many files may be slow or run out of memory on some devices.
What is compatibility mode?
If a PDF has damaged internal data and can't be merged normally, the tool redraws its pages and rebuilds the document instead. The result still merges, but pages become images, so text may no longer be selectable and the file can be larger.
Does it work with password-protected PDFs?
Many encrypted PDFs will not merge correctly. Remove the password in your PDF viewer first, then try again.
