Frequently asked questions

Is there a limit to how many or how large the PDFs can be?
There is no hard limit. Since everything runs in your device's memory, very large files or many pages at once may take longer depending on your device.
Can I merge only some of the pages?
Use Extract Pages or Delete Pages first to keep only what you need, then merge. You can pass files straight through with the chain feature.
