FAQ
Q: Is my data uploaded to a server?
A: No. All PDF merging is performed locally in your browser using pdf-lib. Your files never leave your device.
Q: How many files can I merge?
A: There is no hard limit. However, very large or numerous files may be slow to process in the browser.
Q: Does the order of files matter?
A: Yes. The merged PDF follows the order shown in the list. Use the ↑↓ buttons to reorder files before merging.
