Frequently Asked Questions
Are files uploaded?
No. Merging happens in your browser; PDFs never leave your device.
How is order set?
Files follow the order shown. Use the up/down buttons in the list to reorder.
How many files can I merge?
Recommended up to ~20 files; large batches depend on device memory.
Do signatures/forms stay?
Basic content stays; advanced features (signatures, interactive forms) may not survive merging.
Mixed page sizes?
Pages keep their original sizes; merged PDF can contain mixed page dimensions.
Output version?
Default is PDF 1.7. Choose PDF 1.4 if you need older compatibility.
Limitations?
Very large PDFs or many files can be memory-heavy; merge in smaller sets if needed.
Watermarks?
No watermarks are added.
Privacy?
Fully offline; nothing is sent to a server.
