Questions About Merge PDFs
Do I need to upload my sensitive PDFs to an online server to merge them?
No! Most free online web tools upload your confidential documents to unknown cloud servers. ScanOrbit processes the entire PDF merge locally in your phone’s memory.
Is there a limit on how many PDFs I can combine?
There are no artificial limits. You can combine as many pages and documents as your device storage and memory permit.
Can I reorder individual pages within the merged document?
Yes. Use our Organize PDF tool (`pdf-organize`) to reorder, rotate, or delete specific pages within any merged file.
