Security & Privacy Guarantee

Frequently Asked Questions

Q: Does merging PDFs preserve existing digital signatures?
A: No. Reorganizing PDF pages alters the underlying file structure and hash, invalidating existing digital signatures.
Q: Are my PDF files uploaded during splitting or merging?
A: No. PDF parsing, page rendering, and generation execute entirely in browser memory; files stays on your device.
